GDSN

The Global Data Synchronization Network (GDSN) is a global, cloud-based system that helps suppliers and retailers (like Amazon) exchange accurate, up-to-date product information using a standardized format.

GDSN ensures consistency in catalog data such as:

• Product names and descriptions
• Dimensions and weights
• GTINs and barcodes
• Images and marketing content

Amazon uses GDSN to streamline catalogue updates from vendors, particularly in large-scale or multinational product catalogs. It reduces manual errors and improves listing accuracy.

Benefits of GDSN:

• Real-time updates across all platforms
• Less manual input for vendors
• Increased listing speed and accuracy
• Compliance with global retail standards (GS1)

💡 Example: “If you’re using GDSN, your new product sizes and images will automatically sync with Amazon’s catalog without needing to update listings manually.”

In short:
GDSN is a tool that allows suppliers to automate and standardize catalogue updates with Amazon, improving accuracy and efficiency in product data management.
