Use correct product IDs

When you create new product pages and offer listings, products must be associated with industry-standard IDs for most categories. Product IDs let Amazon match identical products, avoid duplicate listings, and help customers easily find and compare offers. You can check category requirements here.

Product IDs are part of a system of unique identifiers called Global Trade Item Numbers (GTINs). The most common GTINs for creating Amazon catalog pages are UPCs, ISBNs, EANs, and JANs.

Some products don't have a GTIN. If the product is already listed on Amazon, you can list your offer on the existing product detail page without providing a GTIN. If the product isn't listed yet, you can apply for a GTIN exemption for your category (if eligible). Brand owners and manufacturers can also enroll their brands in Amazon Brand Registry to protect their registered trademarks and get a product ID.

What to consider

  • Amazon checks the GS1 standard website to ensure the authenticity of product UPCs

  • The correct product ID is required for the item you're listing. UPCs that don't match the information from GS1 are considered invalid. To ensure the GS1 database has the right information, license UPCs directly from GS1 instead of other third parties.

  • Invalid UPC listings will be removed. This could mean your ASIN creation or selling privileges are temporarily or permanently removed.
  • Many categories have required UPC and GTIN guidelines for the creation of product pages. This includes products sold as bundles or packs.

  • UPC requirements can vary across categories or for different products in the same category.

  • By enrolling in Amazon Brand Registry, you get access to powerful tools. These include proprietary text and image search, and predictive automation based on your reports of suspected intellectual property rights violations.
