Overview

Amazon requires sellers to provide a standard product identifier — such as a UPC, EAN, ISBN, or JAN — when creating new product listings in most categories on the marketplace. These identifiers, collectively known as Global Trade Item Numbers (GTINs), help Amazon match listings to existing catalog entries and maintain data accuracy across the platform. Understanding which product ID your category requires, and whether you qualify for an exemption, is essential before listing any new product.

Key Points / What Sellers Need to Know

• UPC is the default requirement — The vast majority of Amazon categories require a Universal Product Code (UPC) to create new listings. If your product has a manufacturer-assigned UPC, you must use it.
• Private label sellers can request exemptions — Many categories allow private label brand owners to apply for a GTIN exemption, meaning you can list products without a UPC if you manufacture or brand them yourself.
• Books require ISBN, EAN, or JAN — The Books category has its own requirement. All book listings must include an ISBN, EAN, or JAN. Professional sellers who have books without these identifiers may request an exemption.
• Bundles need unique UPCs — If you sell product bundles in categories like Grocery, Home, Toys, or Sports, each unique bundle configuration requires its own dedicated UPC.
• Multi-packs require item package quantity — Categories such as Health & Beauty and Grocery require sellers to specify the item package quantity for multi-pack listings in addition to providing a valid GTIN.
• Some categories have no GTIN requirement — A small number of categories, including Collectible Coins, Trading Cards (for non-major brands), and the Everything Else category, do not require a product ID.

How the GTIN System Works on Amazon

When a seller creates a new product listing, Amazon uses the provided GTIN to check whether that product already exists in its catalog. If a matching entry is found, the seller's offer is added to the existing product page rather than creating a duplicate listing. This system helps prevent catalog clutter and ensures customers see consolidated reviews and pricing from multiple sellers on a single product detail page. Sellers should always use the exact GTIN assigned by the product manufacturer. Purchasing UPCs from unauthorized resellers can lead to listing errors, suppressed listings, or even account-level enforcement actions from Amazon.
