How does the 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-house or third party).
• 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: Data Recipients subscribe to the supplier item(s) or party information in the GS1 Global Registry via their chosen GDSN-certified data pool. 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.
