GS1 Identification Keys

There are 12 major GS1 identification keys, allowing organizations to connect physical events and related information.

GS1 identification (ID) keys are global standards that give organizations efficient ways to access information about their products in the supply chains, and share this information with trading partners.

GS1 ID keys are globally unique, they can be shared between organizations, increasing supply chain visibility for trading partners. ID keys ensure products will always be correctly identified on a global scale, minimizing the risk of confusion and increasing supply chain transparency and traceability for everyone.

All GS1 ID keys can be used by Canadian organizations though, the two most commonly used in Canada are

  • Global Trade Item Numbers (GTINs), used to identify specific products and services and
  • Global Location Numbers (GLNs), used to identify locations and legal entities.
