2. Barcodes and data matrix codes for letter mail
2.1 General information
2.2 Overview of barcodes and data matrix codes for letter mail
Post CH Ltd uses four types of codes for letter mail:
- (A) Shipping barcode
To identify letters with barcode and for electronic track and trace (acceptance, sorting, delivery).
- (B) Value-added service barcode
To indicate the value-added services requested by the sender (for example electronic cash on delivery, return receipt, electronic return receipt, personal delivery).
- (C) Data matrix code
As an identification feature for PP franked consignments (Letter ID light and Letter ID) and as a control element for consignments with barcode (registered, LID and LCS).
- (D) Delivery instructions
To indicate the delivery instructions required by the sender.
- (E) Return note
To indicate the delivery instructions required by the sender for registered domestic mail (R) in combination with a data matrix code.
Important: Different specifications apply to domestic and international mail in each case. These are therefore described separately in this guide.
2.3 The benefits of using barcodes and data matrix codes
Shipping barcodes
Shipping barcodes are used for
- registered (R)
- A Mail Plus (A+)
- Dispomail (A)
- court documents (GU)
- debt collection documents (BU)
- Electronic cash on delivery (BLN)
- Letter with ID check/contract signing (CT)
- Letter with ID check (ID)
- PRIORITY Plus
- international letter mail containing goods (untracked)
Using shipping barcodes enables
- automated, efficient and cost-effective mail processing
- proof of posting
- a detailed confirmation of receipt
- online tracking of letter mail www.swisspost.ch/track-consignments
- for letters with barcode: legally binding objective evidence including Swiss Post liability
- for Letter mail easy: automatic invoicing using the barcode
Value-added service barcodes
Value-added service barcodes indicate which value-added services have been requested for the product specified on the shipping barcode.
Value-added service barcodes are used for
- domestic mail with a shipping barcode
Value-added service barcodes enable
- automated, efficient and cost-effective mail processing
Data matrix codes
Data matrix codes are used for
- letter mail with the Letter ID light identification feature (static data content)
- letter mail with the Letter ID identification feature (dynamic data content)
- Letter with ID check/contract signing
- Letter with ID check
- election and voting consignments
- business reply label with data matrix code
- Global Response with data matrix code
- Registered (R) with the return note “Retour non recommandé”
Using data matrix codes enables
- automated mail processing
- access to other services
- more scope in terms of the design of your consignments
- instructions to be provided for the desired returns processing from eight options
- information about the sorting status
Delivery instructions
Delivery instructions indicate how mail is to be treated during the delivery process.
Delivery instructions are used for
- domestic mail with barcode (registered mail, court and debt collection documents, Letter with ID check and Letter with ID check/contract signing)
Using delivery instructions allows you to
- have your mail delivered in a flexible manner
Registered (R) with the return note “Retour non recommandé”
With the optically recognizable return note “Retour non recommandé”, you order that your registered letter will be treated as an unregistered letter during the returns process in the event it is undeliverable, acceptance is refusedor it is not collected within the storage period. Consignment tracking is thus no longer possible during the returns process. Taxable returns will be invoiced at CHF 0.60.
Note: The old return notes (Return as A Mail or Return as B Mail) have been replaced by the return note “Return as unregistered” incl. data matrix code.
Registered (R) without return note
If you want registered letters to be returned as registered letters, then there is no need for an optical return note, nor for section 5 in any DmC that may be used.
Returned consignments without a return note are also processed as registered mail (R) and retain both the possibility for consignment tracking and liability claims.
These returns are always physically returned to the optically recognizable, unique sender on the consignment. The DmC is not considered in the returns process.
Return notes are used for
- registered domestic mail (R)
- Letter with ID check
- Letter with ID check/contract signing
Barcode for pallets
The barcode for pallets is used for all bulk mailings delivered on pallets:
- A Mail
- B Mail individual items
- B Mail bulk mailing
- OnTime Mail
- Professional Mail
Using barcodes for pallets allows you to
- query the processing status of an order and accurately plan the downstream processes.
Returns processing with data matrix code
Definition of letter mail returns
- a) Undeliverable consignment: The consignment could not be delivered to the recipient for one of the following reasons: Relocation / the recipient could not be determined / address error / recipient is deceased / company is no longer in business / letter box has not been emptied.
- b) Refused consignment: The consignment was able to be successfully delivered, but the recipient refused to accept it.
- c) Uncollected consignment: The recipient was notified about a registered letter to be collected, but did not collect it within seven calendar days.
Returns management
With a Letter ID or Letter ID light, you can choose from eight different return handling options and provide this as an instruction in the DmC.
These options are described in the “Returns” factsheet www.swisspost.ch/returns.
Return instructions cannot be used in the DmC
The DmC is not considered for registered letters (unless there is the return note “Retour non recommandé”).
The DmC is also not permitted for court documents, electronic cash on delivery, Dispomail, Priority Plus and registered international mail.
Requirements for the consignment preparation and DmC
There are specifications for using a DmC with return instructions. These can be found in the relevant section of this manual and in the “Returns” factsheet.
Other restrictions
In general, only ONE postal DmC is permitted for each consignment. Combinations with IFS franking or WebStamp are therefore not possible.

5.1 Indicating delivery instructions for domestic mail
Note the delivery information on the back
Letter with ID check and letter with ID check/contract signing enable you to identify people and/or to obtain signatures through Swiss Post for contracts ordered by telephone or online.

Please note that consignment tracking and liability claims are no longer possible for consignments with the return note “Retour non recommandé” while they are being returned.
The return note can be integrated into the address, combined with the barcode or affixed as an envelope form. For more information, please refer to the section “Applying barcodes and data matrix codes”.
6. Using barcodes for pallets
6.1 Labelling pallets
Labelling pallets and bulk containers
Pallets and outer containers must be processed in accordance with Swiss Post’s current numbering system. They are first consolidated by pallets/bulk containers for each location (e.g. 8500), for each routing area (e.g. 85) and only when no further consolidation is possible by center (e.g. 8) and finally by pallet with remaining items (1–9).
The following options are possible as shown using B Mail bulk mailing (addresses are white for A Mail, blue for a B Mail single item and green for OnTime Mail).
7. Using data matrix codes for letter mail
7.1 Identification feature
Data matrix codes for letter mail can be read only electronically. The condition for delivering a requested letter mail service with data matrix code is compliance with the guidelines described in this manual and mail that is suitable for machine processing. Swiss Post cannot process data matrix codes on consignments which are open, bulky or more than 2 cm thick.
Data matrix codes used by Logistics Services for processing physical letter mail all start with the numerical sequence “75680” and are labelled as “postal data matrix codes”. Letters with postal data matrix codes that reach Logistics Services’ processing channel are identified and treated as mail items.
With the data matrix codes, you can identify entire orders or individual items, track them during sorting and control them in returns processing. While Letter ID light uses static data matrix codes with uniform population, Letter ID allows each individual mailing to be tracked and managed in the returns channel.
Letter ID
- Uniqueness: each consignment for an order has a data matrix code with an individual consignment number
- Dynamic production and individuality
- Positions in the data matrix code that can be freely used by customers for their own purposes
Letter ID light
- Ambiguity: all consignments for an order have the same data matrix code with the same content
- One-off production and duplication possible
- Returns data are only available in the form of images (automatic data management not possible)
Returns can be digitized, disposed of (simple or qualified) or redirected
Address block function, more scope for design of consignments
If you send letter mail with the identification feature, a square data matrix code is added to the franking zone next to the PP impression (A) or address window (B) (both placements possible).
Important: The data matrix code is not a stamp. It merely marks the letter mail concerned.
How to create the data matrix codes:
- Determine which type of data matrix code is best for your consignment processing. Either the static Letter ID light or the dynamic Letter ID, depending on which benefit you want to take advantage of. For more information on the benefits of Letter ID, visit www.swisspost.ch/letterid
- There are three ways to create the data matrix codes:
- A. Create the data matrix code yourself with the “Create postage paid impressions” online service. You can find more information at www.swisspost.ch/online-services → “Create postage paid impression”.
- B. Create the data matrix code with custom-developed software. You can find information on creating the data structure in the section “Generating data matrix codes”.
- C. Create the data matrix code with the assistance of a service provider. You can find information on creating the data structure in the section “Generating data matrix codes”.
- Affix the data matrix code to the layout of your consignment.
- Quick postal check (obtain the final proof; contacts on page).
Information on Letter ID and Letter ID light:
Additional “Address block” function
The size of the advertising zone on envelopes can be increased. You can also add overprints and colour gradients below the address field or to the right of it without paying a surcharge for special mail items. This enables your mailing items to stand out and makes them more effective. The precondition for this is affixing a data matrix code next to the address and with the additional “Address block” function.
For more information on how to position the data matrix code with the additional “Address block” function, visit
- www.swisspost.ch/layout-of-letters → Designing and packaging letters → “Letter creation from A-Z” specifications, in the “Address block” section
7.2 Letter with ID check and Letter with ID check/contract signing franking method
Letter with ID check and letter with ID check/contract signing
With the Letter with ID check (LID) and Letter with ID check/contract signing (LID-CS) services, you can simplify new customer acquisition. You enter the customer data via call centers or using the digital onboarding process. Swiss Post then identifies your customer, creates electronic copies of ID documents and obtains any contract signatures required. With automatic consignment tracking, you have your consignments under control at all times, and the consignment data is exchanged via the DataTransfer interface. You can easily download the ID images via the “Track consignments” web service and archive them in your own system.
Billing is via Letter mail easy directly via the barcode. With an additional static or dynamic data matrix code, you can add additional controls that are relevant to you.
Letter with ID check (LID) and letter with ID check/contract signing (LID-CS) are exclusive services for business customers with a billing relationship.
How to create Letters with ID check or Letters with ID check/contract signing
- Contact your customer advisor.
- The design guidelines can be found in the factsheet with the requirements for designing Letters with ID check and Letters with ID check/contract signing at www.swisspost.ch/bmv-bmid

The business reply label data matrix code does not just make the advertising zone bigger: the stamp can feature an image or a corporate logo or simply be left blank. The data matrix code can also be used to evaluate the response to individual campaigns in the Swiss Post Customer Center.
Only the consignments that are actually returned are billed.
- (A) Data matrix code
- (B) You can create an individual design for the stamp’s image (in colour or black and white) or leave it blank.
- (C) Invoice reference number (8-digit); assigned by Swiss Post and used for billing purposes. You can find it on your invoices.
- (D) Order number (6-digit); can be freely chosen by the customer to distinguish between different campaigns.
To create a data matrix code for business reply labels:
- Apply for a billing relationship with Swiss Post (if you do not already have one).
- Design the postage paid impression using the “Create postage paid impressions”
online service - Get a final proof for the entire layout (contacts)
- Have the business reply labels with data matrix code printed

7.5 Global Response data matrix code franking method
Global Response data matrix code
For international Global Response business reply labels, use the same data matrix code as for your domestic business reply labels. This means that individual campaigns can be evaluated in the Swiss Post Customer Center.
Only the consignments that are actually returned are billed.
To implement Global Response data matrix codes, proceed as follows:
- Contact your customer advisor.
- Generate postage paid impression in the “Create postage paid impressions” online service
- Quick postal check (obtain the final proof; contacts on page).
- Hire the printer of your choice to print business reply labels with a data matrix code.

8. Applying barcodes and data matrix codes
8.1 General information
Letter mail usually offers very little space for design elements. Follow the placement instructions to ensure that your barcodes and data matrix codes are clearly readable.
The placement instructions vary depending on whether you are
- using window envelopes
- using address labels
- applying barcodes and data matrix codes directly onto the item
Barcodes and data matrix code on a single item
Important: Provided there is sufficient space, you can use a shipping barcode, value-added service barcodes, delivery instructions and a data matrix code on a single item. However, only one postal data matrix code may be affixed to each item. Follow the respective instructions for all the codes used.
Addressing and franking design
Observe Post CH Ltd’s general specifications for the design of addressing and franking elements:
“Letter creation from A-Z” specifications:
“PP franking” factsheet:
Marked as mail item
Within the framework of the new postal legislation, which also contains specifications concerning consignment marking, all franking must also include the Swiss Post logo or the note “Post CH Ltd”.
The Swiss Post logo is available at www.swisspost.ch/template.
Sender details
Complete and correctly placed sender details provide clarity to the recipients and allow undeliverable consignments to be returned without delay. There are various options for the placement of the sender details on letter mail.
- Complete sender details include (company) name, street or the P.O. Box, and the postcode and town.
- Compliance with the assigned zones for placements on the front (address side) of the consignment ensures that there is no confusion between the sender and recipient address during processing in the sorting systems.
- Sender details can be placed on the front or on the back.
- The sender address must always be placed higher than the recipient address.
- The sender note can also be placed above the recipient address. In this case, it must be separated from the recipient address by a horizontal separator line and the sender address must be in a single line. For consignments with a barcode, the sender address can also be placed to the right of the barcode.
- If the sender logo includes information on only the town, phone number, e-mail or web address (without street name, P.O. Box number or postcode), it may also be placed outside the sender zone in the advertising zone.
- With complete sender details on the consignment, you will receive returned items without delay, without them having to be routed through our enquiry services, which means you will receive them unopened.
- The following elements are not optically recognizable senders:
- Data matrix codes
- Invoice reference or debtor numbers
- Company logos from a branch structure without adding the branch
In certain circumstances, such details can lead to the consignment being opened in order to determine the sender in the event of returns.
Information on the correct layout for your consignment can be found in the “Letter creation from A-Z” specifications:
8.2 Customer codes on letter mail
Applying non-Swiss Post codes
Customers’ own codes may only be positioned in the advertising zone.
One-dimensional or multi-dimensional codes which are not used by Post CH Ltd for preparing items for mailing may not be applied in the postal zones (franking zone, scanning zone, coding zone). These codes include, among others, QR codes, Aztec codes, MaxiCodes or barcodes or data matrix codes which are non-compliant with Swiss Post.
In addition to the postal codes, each consignment may feature no more than one customer-owned code and one customer-owned barcode.
For information on letter design, see

12. Options for generating barcodes and data matrix codes
12.1 Options for generating barcodes
The most efficient way of applying barcodes to your mail will depend on the volume of mail, the software and hardware available to you, and your data flow requirements. Your Post CH Ltd customer advisor will be pleased to help you evaluate the most suitable solution.
Generating barcodes with a mail processing system
If you have a mail processing system (hardware and software solution for automated mail creation), you can have the barcodes printed at the same time you address your letter mail.
Tip: If you already use a similar system for sending parcels, it can also be used for sending letters – with adapted software and suitable labels.
You can obtain information about mail processing systems suitable for dispatching mail from your customer advisor or directly from a vendor:

13. Posting letters with barcode
13.1 Overview of mailing options
The mailing procedure varies, depending on how the barcodes have been applied to your mail.
Using preprinted barcode labels (PostLabels)
If you obtain the barcodes as labels (PostLabels) from Post CH Ltd, you should use barcode lists “21” (form 210.17) or “23” (form 210.16). You can obtain these in paper form from your acceptance point or customer advisor. Alternatively, you can get them online as a PDF file and print them out yourself.
Ordering barcodes:
To download barcode lists, visit:
- www.swisspost.ch/posting-letters → Declaring consignments → Delivery note and barcode list
To enter mail on the barcode lists
- Stick the smaller duplicate barcodes, (A) located on the sheet of stickers next to the corresponding shipping barcode (B) on the barcode lists. If there are not enough fields, use additional barcode lists to stick on the remaining barcodes.
- Make a note of which consignment barcode you used for which item in case you subsequently need to check which items you sent to a particular recipient.
- Hand in the barcode lists, filled out and with the stickers affixed, together with the corresponding items for posting to the acceptance point. You will be given a receipted copy as proof of posting.
Note: Lists “21” and “23” fulfil the same purpose, but they are handled slightly differently.
For information about selecting the appropriate list, see
List “21”
To enter mail on list “21”
- On list “21” (form 210.17), stick only the first and last duplicate for a consignment. Select the appropriate column for domestic and international mail in each case (“Switzerland” (A) , “R-international” (B) ).
- If you do not use up all successive shipping barcodes for one consignment, stick the duplicates of the unused shipping barcodes on the fields provided for this purpose on the bottom half of the list (C). This is important so that they are not recorded as a mailed consignment.
List “23”
To enter mail on list “23”
- On list “23” (form 210.16) stick all the duplicates for a consignment.
- Mark either “Domestic CH” (A) or “R-international” (B) to indicate whether it is domestic or international mail.
Delivery slip for court documents (not incl. Court Document Online) “22”
Using barcode labels applied by Swiss Post
If you do not want to apply the barcodes yourself, this can also be done at the acceptance point (preparing your consignments and address registration with Swiss Post franking). If you have any questions, please contact your customer advisor.
Information on the “Swiss Post franking” service:
For information about Swiss Post’s barcode labelling service, see
Online tracking (Track & Trace)

14. Posting PP-franked letter mail
14.1 Dispatch list for PP-franked mail
PP-franked letter mail without barcodes is billed on the basis of a dispatch list (AVZ) which is created for every consignment posted. To facilitate the billing of PP-franked mail, Swiss Post provides the “Letters dispatch list” online service or the DataTransfer online data interface.
PP-franked letters with barcode have a Letter mail easy franking licence number in the barcode. Billing is based on the processing data recorded by Swiss Post. Dispatch lists (AVZ) are therefore not generated for these consignments.
Important: The Letter ID light and Letter ID franking methods may only be used via the “Letters dispatch list” online service or the DataTransfer online data interface.
For information about the billing of PP-franked mail, see

15. Generating barcodes
15.1 Basics
Introduction
Barcodes are one-dimensional, machine-readable, graphical representations of data.
- Barcodes consist of parallel strips of alternating dark bars and light spaces, the so-called barcode elements.
- The narrowest element is termed a “module”, and its width in millimetres is the “module width”.
- The width of all wider elements is always a multiple of the module width. Most barcodes use two or four different element widths.
- The module ratio specifies the number of times the narrowest element can fit into the widest element. With a module ratio of 4:1, the widest bar is four times the width of the narrowest one. If a code with four element widths is used, the intermediate elements are either two or three times the width.
- The individual digits and characters of a barcode are represented as a unique sequence of elements of different widths. Exactly how they appear depends on the character set used.
- A barcode always begins with a start character and ends with a stop character. These contain information about the type of barcode, the character set used and the direction of scanning.
Quiet zones
Quiet zones are the blank areas around the barcodes that must be left free of any printing. This ensures that there is sufficient distance from other barcodes, text or design elements that could interfere with scanning.
Barcode 128
Shipping and value-added service barcodes are based on the standardized barcode 128 symbology. This barcode is licence-free, widely used and supported by many software programs.
Character sets
Barcode 128 provides various character sets to represent the data. Character sets C and B are used for Post CH Ltd letter mail.
Character set C (numeric)
Each character in this set consists of a pair of digits with a value from “00” to “99”. It is therefore possible to assign two digits to each character, which allows the data density to be doubled. The barcode is then shorter.
Character set C is used for:
- Shipping barcodes for domestic mail
- Value-added service barcodes
Character set B (alphanumeric)
The alphanumeric character set B consists of individual letters, digits and special characters. Compressed representation is not possible. The barcode is thus longer.
Character set B is used for:
- Shipping barcodes for international mail
- Value-added service barcodes (old version)
Module ratio
Barcode 128 uses four different element widths with a module ratio of 4:1.
Technical requirements for printing barcodes
Your barcodes will be legible if you comply with the following specifications:
Printer resolution
Use a printer with a physical print resolution of at least 600 dpi (dots per inch).
Module width
At a minimum print resolution of 600 dpi, the module width must be between 0.335 and 0.7 mm.
Printing
The bars must be printed using a matt black ink with even coverage and good edge definition.
Print contrast signal (PCS)
The contrast factor (PCS, dimensionless value according to DIN EN 797) must be greater than 0.7 for a wavelength range of between 620 and 900 nm. Properly printed black codes on light matt papers will be able to reliably achieve this contrast factor.
Opacity
The opacity of the label material must be at least 0.75% (DIN 53 146, ISO 1831). This value may be lower if the surface of the mail item is white and is not patterned or textured.
Quality standard
The print quality must be at least grade B according to DIN EN ISO/IEC 15416.
Note: If you use a modern laser printer to print your barcodes on pure white paper, they will usually meet these requirements.
15.2 Generating shipping barcodes for domestic mail
Specification
Shipping barcodes for domestic mail are created in compliance with the following specification:
| Type | Character set | Standard |
|---|---|---|
| Barcode 128 | Character set C (numeric) | ISO/ IEC 15417 |

| 106 | Stop character | |
Positions 1 to 3: start character (3 positions)
The value “105” signifies character set C.
Positions 4 and 5: identifier (2 positions)
Post CH Ltd has designated identifier “98” for letter mail.
Positions 6 to 13: franking licence (8 positions) or product code (2 positions) and franking licence (6 positions)
The franking licences are issued by Swiss Post and identify the individual customer. The data structure varies depending on the product selected:
| Product | Data structure |
|---|---|
| Registered (R) | XXXXXXXX (franking licence) |
| A Mail Plus (A+) | “01” (product code) and XXXXXX (franking licence) |
| Dispomail (A) | “02” (product code) and XXXXXX (franking licence) |
| Court document (GU) | “03” (product code) and XXXXXX (franking licence) |
| Electronic cash on delivery (BLN) | “04” (product code) and XXXXXX (franking licence) |
| Debt collection documents (DD) | “05” (product code) and XXXXXX (franking licence) |
| Letter with ID check/contract signing Sent (CT) | “07” (product code) and XXXXXX (franking licence) |

| Letter with ID check Sent (ID) | “09” (product code) and XXXXXX (franking licence) |
| Letter with ID check Return (A+) | “08” (product code) and XXXXXX (franking licence) |
Positions 14 to 21: consignment number (8 positions)
The eight-digit consignment number is assigned for each consignment in ascending order or according to a freely definable system (value range 00000001 to 99999999). It is always entered starting on the far right of the reserved barcode positions and any remaining free positions are padded with zeroes. Each consignment number must be unique within a period of 180 days, i.e. it may be assigned only once during this period.
Positions 22 to 23: check digit pair
Positions 24 to 26: stop character (3 positions)
Value “106”
Barcode modules
The start character and the digit pairs each comprise 11 modules, split into 3 bars and 3 spaces. The stop character comprises 13 modules, split into 4 bars and 3 spaces.
Representation size
The representation size of the barcodes is obtained by multiplying the number of modules by the module width:
| Number of characters | Number of modules |
|---|---|
| 1 start character at 11 modules | 11 modules |
| 9 digit pairs at 11 modules each | 99 modules |
| 1 check digit pair at 11 modules | 11 modules |
| 1 stop character at 13 modules | 13 modules |
| Total | 134 modules |
Representation size = number of modules × module width 134 modules × 0.335 mm = 44.9 mm

Homologation
Important: Before they are used for the first time, all barcodes, data matrix codes and barcode lists you create must be homologated by Post CH Ltd. For this they are selected using special test systems and checked for readability and data integrity. If they meet all the criteria, they are then approved for operational use.This ensures that letter mailings can be processed later without problems (see “Homologation”). Swiss Post accepts no liability for mail items that cannot be processed correctly due to non-homologated, incorrect barcodes.

- × 9
- × 7
- 40
- 42
- 12
- 16
- 3
- 35
- 27
- 63
= 238
238 : 11 = 21,63636363…
(Result without decimal places) × 11
21 × 11 = 231
(Sum of results of weighting) – 231
238 – 231 = 7
11 – Remainder
11 – 7 = 4
(Result of calculation) = 4
Result = 1 … 9 → check digit corresponds to result (here 4)
Result = 10 → check digit is 0
Result = 11 → check digit is 5
Positions 15 to 16: country of posting (2 positions)

| Total | 178 modules |
Representation size = number of modules × module width
178 modules × 0.335 mm = 59.6 mm
Note: The barcode may also be shorter. Some barcode generators reduce the representation size by temporarily switching to character set C for digits then switching back again.
15.5 Layout of shipping barcodes for international mail
Structure of shipping barcodes for international mail
Shipping barcodes for international registered mail (R) should be created according to the same specifications as for domestic mail. However, some elements of the data structure and layout differ. These differences are set out below.
Consignment barcodes for international registered mail (R) comprise:
- (A) the horizontally printed product code (capital letters)
- (B) the horizontally printed barcode
- (C) the horizontally printed human-readable text showing the information content of the shipping barcode. On international mail, this text is not separated by dots. However, blank spaces may be used to make it easier to read. Shipping barcodes for international mail can be readily identified by the “CH” in the human-readable information under the barcode.
- (D) the blank quiet zones around the barcode. These areas must be left blank so that the barcode can be reliably read
- (E) optional: handling instructions (“Please scan – Signature required, Veuillez scanner – Remise contre Signature”)
- (F) optional: the horizontally printed full-text product designation
- (G) the Swiss Post logo
Important: For international registered mail (R), the PP impression is not integrated into the shipping barcode, but instead is placed in the franking zone at the top right of the mail item. Even if you use window envelopes, the impression must always be outside on the envelope.
Note: The structure for PRIORITY Plus or Untracked barcodes can be found in the instructions for harmonized labels. To obtain these instructions, please contact your international customer advice service or international@post.ch.
Dimensions
The following dimensions must be observed so that the shipping barcodes for international mail can be reliably read:

15.9 Creazione di istruzioni di recapito per invii per la Svizzera
Specifiche
Le istruzioni di recapito per gli invii per la Svizzera vengono create in base alle specifiche di seguito indicate.
| Tipo | Set di caratteri | Norma |
|---|---|---|
| Codice a barre 128 | Set di caratteri C (numerico) | ISO/IEC 15417 |
Riempimento di dati
Struttura dei dati
I codici a barre dell’invio per istruzioni di recapito comprendono:
- il carattere iniziale (valore «105»)
- le due coppie numeriche per il contrassegno dell’istruzione di recapito
- la coppia di cifre di controllo
- il carattere finale (valore «106»)
Esempio:
| 105 | Carattere iniziale | |
|---|---|---|
| 25 | Contrassegno dell’istruzione di recapito | Contenuto utile |
| 12 | ||
| 59 | Coppia di cifre di controllo (codice a barre 128C) | |
| 106 | Carattere finale | |
1a-3a posizione: carattere iniziale (tre caratteri)
Il valore «105» indica il set di caratteri C.
4a-7a posizione: contrassegno codificato (quattro caratteri)
| Designazione dell’istruzione di recapito | Struttura dei dati dell’istruzione di recapito |
|---|---|
| 2o recapito il sabato seguente | 2512 |
8a-9a posizione: coppia di cifre di controllo
10a-12a posizione: carattere finale (tre caratteri)
Valore «106»
Omologazione
Importante: prima del primo impiego, tutti i codici a barre, i codici a matrice e le liste di codici a barre allestiti devono essere omologati da Posta CH SA. Essi vengono selezionati con sistemi sviluppati appositamente per verificare la leggibilità e l’integrità dei dati. Se soddisfano tutti i criteri, vengono autorizzati per l’impiego produttivo. In tal modo si garantisce che gli invii di lettere potranno essere elaborati senza problemi in un secondo tempo (cfr. «Omologazione»). Se gli invii non possono essere elaborati correttamente a causa di codici a barre o a matrice non omologati ed errati, la Posta declina qualsiasi responsabilità.
15.10 Creazione di codici a barre per pallet
Specifiche
I codici a barre degli invii per pallet vengono allestiti secondo le specifiche di seguito riportate.
| Tipo | Set di caratteri | Norma |
|---|---|---|
| Codice a barre 128 | Set di caratteri C (numerico) | ISO/IEC 15417 |
Riempimento di dati
Struttura dei dati
I codici a barre per pallet comprendono:
- il carattere iniziale (valore «105»)
- le nove coppie numeriche del contenuto utile
- la coppia di cifre di controllo
- il carattere finale (valore «106»)
Esempio:
| 105 | Carattere iniziale | |
|---|---|---|
| 91 | Contrassegno postale pallet | Contenuto utile |
| 01 | Codice prodotto | |
| 31 | Licenza d’affrancatura | |
| 78 | ||
| 00 | Numero d’ordine | |
| 00 | ||
| 03 | Circoscrizione di avviamento | |
| 11 | Numero del pallet | |
| 01 | ||
| 40 | Coppia di cifre di controllo (codice a barre 128C) | |
| 106 | Carattere finale | |
1a-3a posizione: carattere iniziale (tre caratteri)
Il valore «105» indica il set di caratteri C.
4a e 5a posizione: contrassegno postale (due caratteri)
Il contrassegno «91» è stato stabilito da Posta CH SA per i pallet.
6a e 7a posizione: codice prodotto (due caratteri)
Ogni prodotto ha la sua struttura di dati.
| Prodotto | Struttura dei dati |
|---|---|
| Posta A | «01» (codice prodotto) |
| Invii singoli della Posta B | «02» (codice prodotto) |
| Invii in grandi quantità della Posta B | «03» (codice prodotto) |
| OnTime Mail | «04» (codice prodotto) |
| DIR | «11» (codice prodotto) |
| Posta B2 Importazione | «20» (codice prodotto) |
8a-11a posizione: licenza d’affrancatura (quattro caratteri)
Le licenze di affrancatura vengono assegnate dalla Posta e identificano i singoli clienti.
12a-15a posizione: numero d’ordine (quattro caratteri)
Il numero d’ordine a quattro caratteri viene assegnato per ciascun invio in ordine crescente o secondo un sistema a libera scelta (campo di valori da 0000 a 9999). Viene sempre registrato nelle posizioni riservate al codice a barre partendo da destra; gli spazi vuoti vengono riempiti con degli zeri. Ogni numero d’invio deve essere univoco per 60 giorni; pertanto, in questo lasso di tempo può essere assegnato una sola volta.
16a e 17a posizione: circoscrizione di avviamento (CA) del pallet (due caratteri)
Le indicazioni della circoscrizione di avviamento sono obbligatorie. Le relative informazioni sono reperibili nel piano numerico alla pagina web www.posta.ch/prestazioni-preliminari.
18a-21a posizione: numero progressivo del pallet (quattro caratteri)
Quanto più nel dettaglio dichiarate i pallet (ad es. numero del pallet), tanto più alto è il valore informativo per voi! Il pallet non può essere contrassegnato con «0000».
22a e 23a posizione: coppia di cifre di controllo
24a-26a posizione: carattere finale (tre caratteri)
Valore «106»
Moduli dei codici a barre
Il carattere iniziale e le coppie numeriche sono costituiti da 11 moduli, suddivisi in tre strisce e tre spazi vuoti. Il carattere finale è costituito da 13 moduli, suddivisi in quattro strisce e tre spazi vuoti.
Dimensioni di visualizzazione
Le dimensioni di visualizzazione dei codici a barre dipendono dal numero e dalla larghezza dei moduli.
| Numero di caratteri | Numero di moduli |
|---|---|
| 1 carattere iniziale da 11 moduli | 11 moduli |
| 9 coppie numeriche da 11 moduli | 99 moduli |
| 1 coppia di cifre di controllo da 11 moduli | 11 moduli |
| 1 carattere finale da 13 moduli | 13 moduli |
| Totale | 134 moduli |
Dimensioni di visualizzazione = numero di moduli × larghezza del modulo 134 moduli × 0,335 mm = 44,9 mm
Struttura dei codici a barre per pallet
Componenti dei codici a barre per pallet:
- (A) the horizontally printed product code (capital letters)
- (B) the horizontally printed barcode
- (C) the human-readable text showing the information content of the shipping barcode
- (D) the blank quiet zones around the barcode. These areas must be left blank so that the barcode can be reliably read.
Dimensions
The following dimensions must be observed so that the shipping barcodes for pallets can be reliably read:
| Key | Description | Mass |
|---|---|---|
| A | Module width | 0,335 mm (see “Introduction”,) |
| B | Module ratio | 4:1 (see “Introduction”,) |
| C | Module height | At least 5 mm |
| D | Distance between product code and barcode | At least 5 mm |
| E | Trailing quiet zone | At least 8 mm |
| F | Distance between barcode and human-readable information | At least 1 mm |
Text content and text styles
The following specifications apply to the text elements:
| Key | A | B |
|---|---|---|
| Text element | Product code “T & T” (Track & Trace for pallets) | Human-readable information “Track & Trace pallets: XX.XX.XXXX.XX.XXXX” |
| Font | Arial bold | Arial bold |
| Recommended size | 55 pt | 9 pt |
| Minimum size | 12 pt | 6 pt |
| Text colour | Black | Black |
Homologation
Important: Before they are used for the first time, all barcodes, data matrix codes and barcode lists you create must be homologated by Post CH Ltd. For this they are selected using special test systems and checked for readability and data integrity. If they meet all the criteria, they are then approved for operational use. This ensures that letter mailings can be processed later without problems (see “Homologation”). Swiss Post accepts no liability for mail items that cannot be processed correctly due to non-homologated, incorrect barcodes or data matrix codes.
