A comprehensive site to explain all rules, how and when, to define a new set of GTIN or EAN code, required for any new or heavily modified product. The GS1 GTIN Management Rules provide a standardized framework for determining when a product modification necessitates the assignment of a new Global Trade Item Number (GTIN).
This decision-support tool outlines specific criteria across sectors such as healthcare and retail to maintain consistency in global supply chains. It establishes three guiding principles:
- Whether a change is material to the consumer or supply chain partner.
- If physical dimensions or weight exceed defined tolerances.
- Whether regulatory or certification changes require unique identification.

By defining these thresholds, the service prevents data fragmentation and facilitates accurate tracking, stocking, and sales without identification ambiguity.
Manufacturing and quality assurance professionals apply these rules to maintain data integrity during product lifecycle management and engineering change orders. When engineers modify product specifications, such as net weight or material composition, they use the GS1 logic to determine if a new identifier is required to prevent inventory reconciliation errors.
