Can I re-use a GTIN (Barcode number)?

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.  Please refer to the GS1 New Zealand User Guide

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.
