The Global Data Synchronisation Network is an internet-based, interconnected network of interoperable data pools and a global registry known as the GS1 Global Registry, that enable companies around the globe to exchange standardised and synchronised supply chain data with their trading partners using a standardised Global Product Classification.

GDSN assures that data exchanged between trading partners is accurate and compliant with universally supported standards.

GDSN consists of supplier/retailer trading partner, data pools that hold and process trading partner data and the GS1 Global Registry, a directory that helps locate data sources and keep relationships between trading partners in sync.

[edit] Global identification numbers

The Global Location Number (GLN) and the Global Trade Item Number (GTIN) are the global identification numbers in the GDSN. The GLN is the identifier for legal entities, trading partners and locations while the GTIN is the identifiers for trade items.^[1]
