GCID allows Amazon to connect product listings across regions and keep data consistent. It helps with tracking inventory, pricing, reviews, and product information on a global scale. As a seller, the GCID can be useful for managing listings and staying on top of how your products appear in different Amazon marketplaces. How Do I Find a Product’s GCID? To locate a product’s GCID, you’ll need to access the product page on Amazon’s seller central. Once on the product page, look for the “Manage inventory” link. Click that to open the inventory management page for that product. The GCID will be listed at the top of the page, labeled as “Amazon catalog number”. It will be an alphanumeric code, usually starting with a B or X.

The GCID never changes for a product, even if you update the title, description or images. It permanently links the product to all versions and listings across regions. The GCID is a key part of how Amazon is able to provide a unified product catalog and shopping experience worldwide.

For sellers, the GCID gives you a single point of reference to track your product’s performance on a global scale. By monitoring your product’s GCID, you can gain valuable insights into which listings are most effective, how pricing varies in different marketplaces, and make data-driven decisions to optimize your Amazon business across regions.
