What is the GTIN 13 barcode?
The GTIN 13 code is comprised of 13 digits. It is the most widely used commercial distribution code in the world.
It is shown on all marketed products.
GS1, an international agency located in Brussels, manages it internationally.
Structure of the GTIN 13 barcode for serial publications
For serial publications, the GTIN 13 barcode is structured as follows:
- the first 3 digits correspond to the 977 prefix assigned to serial publications,
- the next 7 digits correspond to the ISSN (without the hyphen and without the end check digit),
- The 11th and 12th characters are variable and the publisher can use them to express additional information (e.g.; change of price), and
- the 13th character is a check digit calculated according to the modulo 10 formula.
To calculate or verify it, you can use the simulator on the GS1 website.
The GTIN 13 barcode can be completed by a 2 or 5-digit add-on that usually indicates the issue number.
Calculate a GTIN 13 code
To calculate the GTIN code for your serial publication, you first must apply for your ISSN
Create the image of a GTIN 13 code
Once the GTIN 13 code is calculated, you have to create the corresponding image (succession of vertical bars) that will be reproduced on copies of your publication.
You can either:
– produce this image yourself with appropriate software, or
– order high-definition films from specialised companies (the ISSN International Centre does not provide contact details for these companies).
Barcode – definition
A barcode is the optical translation, in the form of alternating vertical bars and spaces, of a digital or alphabetic code used to identify a product.
