I want to put a new range of products on the market, and need a barcode as soon as possible

If you already are a member of a GS1 Member Organisation (MO) you will be able to allocate a new GTIN to your products from your current GS1 Company Prefix. 

If you are not a member of a GS1 Member Organisation, you should contact your local GS1 Member Organisation office and they will explain how you can join GS1. They will provide you with a GS1 Company Prefix and the specifications in your language.
