GS1 Identification (ID) Keys
GS1 identification (ID) keys are global standards that give organizations efficient ways to access information about their products in the supply chain, and share this information with trading partners.
GS1 ID keys are globally unique and increase supply chain visibility. These ensure products will always be correctly identified on a global scale thus minimizing the risk of confusion and enhancing supply chain transparency and traceability for everyone.
