Overview

Amazon requires sellers to provide valid product identifiers — such as UPCs, EANs, JANs, or ISBNs — when listing items from designated brands. These identifiers, collectively known as Global Trade Item Numbers (GTINs), help Amazon match products to the correct catalog pages and prevent duplicate listings that confuse shoppers. Sellers who fail to include valid product IDs risk having their listings rejected outright or suppressed from Amazon search results.

Key Points / What Sellers Need to Know

• Valid product IDs are mandatory for designated brands — Amazon maintains a list of brands that require a legitimate UPC, EAN, JAN, or ISBN. Listings for these brands without a valid identifier will not appear in search or browse results.
• New listings will be rejected — If you attempt to create a new listing for a designated brand without a valid product ID, the listing creation process will fail and you will receive a listing error.
• Existing listings will be suppressed — Listings that are already live but lack a valid product ID will be hidden from Amazon search and browse until a valid ID is added.
• Previous GTIN exemptions may not apply — Even if you were previously granted a GTIN exemption, listings for designated brands will still be suppressed if they lack a valid product ID. The exemption does not override this requirement.
• Duplicate listings hurt everyone — Amazon's research shows that missing or invalid product IDs are a leading cause of duplicate listings, which make it harder for customers to find and compare products.

How Product IDs Work on Amazon

Every physical product sold globally is typically assigned a unique identifier by its manufacturer or brand owner. In the United States, this is usually a Universal Product Code (UPC), while European products use European Article Numbers (EANs), Japanese products use Japanese Article Numbers (JANs), and books use International Standard Book Numbers (ISBNs). Amazon uses these identifiers to match seller offers to the correct product detail pages in its catalog. When multiple sellers list the same product with the same valid GTIN, their offers appear together on a single product page, giving customers a clear and consolidated shopping experience. Without a valid product ID, Amazon cannot reliably determine which product a seller is offering, leading to catalog fragmentation and a poor customer experience.
