The GCID code automatically assigned to each product will not be displayed in the product information on the product details page or the “Manage Inventory” page. To view the GCID code assigned to a product, sellers can download the “Inventory Report” in the backend and view the GCID code of the product from here.
(1) From the “Inventory” drop-down menu, select “Inventory Report”
(2) From the “Select Report Type” drop-down menu, select “Sale Product Report”.
(3) After generating the report, open the file using a spreadsheet program (such as Microsoft Excel).
(4) Find column W (Product Code) in the report. If Amazon has assigned a GCID code to the seller’s product, the seller will see a 16-character GCID code consisting of numbers and letters (without spaces or hyphens). It should be noted that the GCID code of products listed before brand registration will not be automatically updated after registration and must be manually updated in batches.
