Overview of Global Data Synchronization Network (GDSN)

Emerging of GDSN

  • The industrial sector is currently in the era where the retailers, manufacturers and distributors have entered a promising, yet challenging, period in their relationships. As they recognize the need of working closely to improve operational efficiency, more efficient information sharing and management has become a critical issue.
  • Traditionally, they exchanged product information using manual, paper-based processes which led to inefficiencies, errors and duplicate labor efforts among trading partners.
  • This gave rise to the need for a standards-based data synchronized model – Global Data Synchronization Network(GDSN).

What is GDSN?

  • The Global Data Synchronization Network (GDSN) is an internet-based, interconnected network of inter-operable data pools and a global registry known as the GS1 Global Registry, that enables companies around the globe to exchange standardized and synchronized supply chain data with their trading partners using a standardized Global Product Classification.
  • GDSN assures that data exchanged between trading partners is accurate and compliant with universally supported standards.
  • Organizations are leveraging the GDSN to streamline how product, service, location, organization, price and promotion data is created and exchanged within their own enterprise.

GDSN consists of the following : 

  • Supplier/retailer trading partner
  • Data pools that hold and process trading partner data, such as Agentrics (formerly Worldwide Retail Exchange) and 1SYNC (formerly Transora and UCCnet).
  • GS1 Global Registry, a directory that helps locate data sources and keep relationships between trading partners in sync. It matches subscriptions to registrations to facilitate the synchronization process.
  • A set of standards established by EAN International and the Uniform Code Council, Inc. (EAN•UCC) through  the Global Standards Management Process (GSMP).
  • Enterprise software for product information management.

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.


  • The GDSN is a network of data pools that facilitates the synchronization of item information between retailer and suppliers through a single global registry.
  • The value of the GDSN is that a retailer and supplier can have a single point of entry into the network through their selected data pool.
  • Once connected, they can subscribe to or publish all of their item information in a single and consistent process for all trading partners that are connected to the GDSN.
