GDSN stands for Global Data Synchronization Network (GDSN) and is the world’s largest product data network.

GDSN makes it possible for any company, in any market, to share high-quality product information seamlessly. Because companies of all sizes need the same thing—timely and reliable product information—to ultimately benefit consumers and patients.

The GDSN enables manufacturers and sellers of goods to harmonize information about their products with their customers.  Retailers and other buyers of goods subscribe to vendor catalogs and receive updates on them.

Manufacturers and sellers benefit by having only one catalog to maintain and update. Buyers benefit from having item information continuously updated to ensure it is correct and current.

Frequently Asked Questions

GDSN stands for Global Data Synchronization Network. It is a global network that facilitates the exchange of standardized product data between trading partners, such as manufacturers, suppliers, retailers, and distributors. GDSN ensures that all parties have access to accurate and up-to-date product information, improving data accuracy and efficiency throughout the supply chain.

GDSN offers several benefits to businesses and the supply chain. It ensures consistent and accurate product data across all trading partners, reducing errors and discrepancies. This leads to improved inventory management, faster product introductions, enhanced traceability, and streamlined compliance with regulations. GDSN also enables better data-driven decision-making and helps businesses respond more effectively to changing market demands.

GDSN uses a standardized framework to synchronize product data across the supply chain. Manufacturers and suppliers publish product information to a central data pool using GDSN-compliant standards. Retailers and distributors then subscribe to this data pool to access and integrate the product information into their systems. Any updates or changes made by the manufacturer are automatically propagated to all subscribing parties, ensuring data consistency.

GDSN facilitates the exchange of a wide range of product information, including item descriptions, attributes, pricing, packaging details, images, nutritional information, safety data, and regulatory compliance information. This comprehensive data exchange ensures that all relevant details about a product are consistently available to all supply chain partners.
