GTIN-14 consists of 14 digits. You create GTIN-14 using an initial logistic variant, a GS1 Company prefix, a serial number, and a check digit.

  • The logist variant is a number between 1 and 9. The numbers 1 to 8 are used to create new GTIN-14 to different packaging levels of a product. It is therefore possible to create new GTIN-14 for up to 8 levels of packaging of the same product. Note that the logistic variant 9 is only used for items with varying dimensions (such as weight, size or length) or varying numbers.
  • GS1 Company prefix consists of 6-9 digits.
  • The serial number consists of 3-6 digits depending on the length of the company prefix. We recommend that you number the items so that the first item is numbered “… 001”, the second article gets the number “… 002”, and so on.
  • The check digit is calculated here.

To create GTIN-14 using a GS1 Enterprise prefix that has nine digits:

If the company prefix has fewer than nine digits, create the item number in the same way as above, but the serial number will consist of more than three digits.

When you subscribe to a GS1 Company Prefix from GS1 Sweden, the Generate Number service, which helps you to create GTINs, is included. The service provides the entire number, including the check digit. You can save your numbers by registering your products with the My Products function. Both tools are accessed via MyGS1.
