How do you determine how many product codes you need?

Each product code starts with a company prefix, which is expanded to a full product code. So, to choose the right company prefix length, it's important to think about how many product keys you'll need. By creating the appropriate company prefix, you start an annual subscription and become a member of GS1.

When choosing the length, take into consideration:

New product


The possible expansion of the range. So think in the long term!



Additional packaging variations of products because these also need to be identified.

Remember that all sizes and colours of a garment require a different GTIN.

Still no idea how many you will need in a few years? Don't panic: you can always order an extra subscription to a code package if you ultimately need more identification numbers than initially anticipated.
