Globally unique identification keys

 

GS1 ID Keys give companies efficient ways to access information about items in their supply chains, and share this information with trading partners.

ID Keys enable organisations to assign standard identifiers to products, documents, physical locations and more.

Because GS1 ID keys are globally unique, they can be shared between organisations, increasing supply chain visibility for trading partners.

To build a GS1 ID key, your organisation must become a member of GS1 and obtain a GS1 company prefix. This will form the basis of your ID keys.

There are 11 GS1 ID keys, allowing organisations to connect physical events and related information, as in the table below.
