GTIN (Barcode number) Allocation and Change Rules

Any change to a product, including product descriptions and packaging may require a new GTIN please use the Decision Support Tool to help you decide if a new GTIN is required. 

If you have any questions please email

The principles are that the brand owner is responsible for allocating GTINs and each variant of a product must be identified with its own unique GTIN.
