Keywords: re-use re-using GTIN barcode allocating
GTINs (Barcode numbers) that have been allocated and have entered the market may never be re-used.
Note: The Barcoding basic user guide V3 discusses re-using item numbers, this information is now INCORRECT. An amended version is pending.
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 firstname.lastname@example.org
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.
