Can I re-use a GTIN?

Keywords: re-use re-using GTIN barcode allocating

GS1 has issued a Decision Support Tool to help you decide if a new GTIN is required. 


Broadly 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.

The complete Rules may be found at

 GTINs that have been allocated and used once may never be re-used. Re-use was permitted except on medical and pharmaceutical products until November 2018 subject to various conditions but it is now forbidden.

The Barcoding basic user guide V3 discusses re-using item numbers.  Note that the information it contains is now INCORRECT.  An amended version is pending.

Version 2 issued 6 November 2018
