How does GDSN work?

The GDSN works via a network of interoperable data pools and the GS1 Global Registry to exchange data from trading partners.

Suppliers and customers willing to synchronise item, and location (party) data with each other will perform the 5 following basic steps detailed below:

  • Step 1: Suppliers prepare internal data and systems to match GS1 Standards (GTIN, GLN, etc.)
  • Step 2: Suppliers upload their data to a GDSN-certified source data pool of their choice (in Ireland this is
  • Step 3: The data pool sends basic information about each item (or party) to the GS1 Global Registry. The GS1 Global Registry holds this information and the location of each item’s (or party’s) data pool.
  • Step 4: Retailers, search the GS1 Global Registry via their chosen GDSN-certified data pool for the item(s) or party for which they want to subscribe. The GS1 Global Registry identifies the source data pool of the requested item(s) or party.
  • Step 5: Using a synchronisation engine, trading partners perform the publication/subscription process. Thereafter, item (or party) information can be automatically and continuously synchronised between their respective data pools.
