How does GDSN work?
GDSN - GS1 Global Data Synchronisation Network
The GS1 Global Data Synchronisation Network connects trading partners to the GS1 Global Registry via a network of interoperable GDSN-certified data pools.
Within this Network, trade items are identified using a unique combination of the GS1 identification keys called Global Trade Item Numbers (GTIN) and Global Location Numbers (GLN).

The GS1 Global Registry is the GDSN's “network facilitator and information directory” that guarantees the uniqueness of the registered items and parties. It provides data pools with the critical information to establish data synchronisation communications in the network and ensures they are using a standard set of messages, validation rules, and processes.
GDSN Certified Data Pools are electronic catalogues of standardised item data. They serve as a source and/or a recipient of master data. Data pools can be run by a GS1 Member Organisation or by a solution provider.
The GDSN-certified data pool in Australia
is GS1 Australia's GS1net - Data Synchronisation Service.
An up-to-date list of all GDSN-certified data pools is always available at
