For most categories, you are required to associate your products with industry-standard product identifiers to create new product pages and offer listings on Amazon. These IDs help ensure product page accuracy by matching listings to products that already exist in the Amazon catalog.
Product IDs are part of a system of unique identifiers called GTINs, or Global Trade Item Numbers. The most common GTINs used to create Amazon catalog pages are Universal Product Codes (UPCs), International Standard Book Numbers (ISBNs), European Article Numbers (EANs) and Japanese Article Numbers (JANs). Product IDs are different from Amazon Standard Identification Numbers (ASINs) because they are used by many systems outside of Amazon.
To find a product ID:
|ISBN: 10 digits or 13 digits. Include the letter X if the ISBN ends with that letter.|
|UPC: 12 digits. Include the digits on the left and right sides of the bar code.|
|EAN, JAN: 13 digits|
|GTIN-14: 14 digits|
If you use the Add a Product tool to list products, enter the product ID in the search bar to find it in the Amazon catalog. If you use an inventory file template, enter the product ID in the product-ID field.
If your product is a bundle or a pack, make sure to add the correct product ID for that pack and item quantity rather than the product ID for a single item contained in the pack.
