Global Data Synchronisation Network (GDSN)

Manufacturers and retailers can exchange their product master data globally over the GDSN. Because GDSN is based on GS1 standards, the data only needs to be entered into one data pool. This is a huge advantage for both suppliers and retailers: the cost for different processes is reduced and efficiency in the supply chain increased.

The Global Data Synchronisation Network (GDSN) connects around 30 certified data pools around the world, which approximately 25,000 companies use. These data pools all speak the same language: GS1 XML. The GDSN draws on a central register, the Global Registry. This enables global data exchange across multiple data pools. The GS1 Global Product Classification (GPC) ensures that all products have a unique classification.


  • The supplier adds product information to their data pool
  • Key information is transmitted to the Global Registry
  • A dealer subscribes to another dealer's data on their own data pool
  • The supplier’s data pool transmits that data to the dealer’s data pool
  • The dealer sends a receipt confirmation to the supplier
