How GDSN works

The GS1 Global Data Synchronisation Network® (GDSN®) is a network of interoperable data pools enabling collaborating users to securely synchronise master data based on GS1 standards. GDSN supports accurate, real-time data sharing and trade item updates among subscribed trading partners.

This means organisations can have confidence that when one of their suppliers or retailers updates their database, their own database is similarly updated as a result. Everyone has access to the same continuously refreshed data. This automatic and efficient exchange helps in meeting the demand of today's data-hungry consumers.

For this to happen, each organisation needs to join a data pool certified and tested by GS1, who connect to the GS1 Global Registry®, a central directory which keeps track of connections, guarantees the uniqueness of data and ensures compliance with shared GS1 standards. There are many data pools spread across the world.
