To sell a product available in the Amazon catalog, you need to match it to the existing ASIN by creating an offer. If your product is not in the Amazon catalog, you will have to create a single new ASIN for the product.
To protect the onsite shopping experience for our customers, we limit the number of listings (offers and ASINs) you can create in a given week until you establish a sales history with Amazon. As you increase your sales, your capacity will increase. We encourage you to prioritize the products you are listing to increase your sales quickly.
Additionally, if you are an established seller and have created a high number of new listings, we reserve the right to temporarily remove your ability to create new listings. We will reevaluate your status on a weekly basis.
If you think your listing creation privileges have been removed in error, please contact Seller Support.
Creating a new ASIN when the same product already exists in Amazon’s catalog is prohibited and can result in your ASIN creation or selling privileges being temporarily suspended or permanently removed.
Matching your products to existing products in Amazon’s catalog helps drive a high-quality customer experience. Matching to an existing product instead of creating a duplicate listing allows you to more fully benefit from buyer interest and traffic for that product.
Duplicates are most commonly created when one or more of the following happens:
Ensure that you always use the appropriate UPC, EAN, ISBN, ASIN, or JAN code when listing a product. The codes are reliable data that can be used to match your products to existing products in the catalog. Using incorrect UPC, EAN, ISBN, ASIN, or JAN codes to list a product is prohibited and can result in your ASIN creation privileges being suspended or permanently removed. Listed below are alternatives to help you list your product if it does not have one of these standard product identifiers:
If you are the brand owner or manufacturer of your own products and if you can uniquely identify each product with other attributes such as model number or style number, you might be eligible to register your brand with the Amazon Brand Registry, which allows you to use an alternative product identifier. Visit Amazon Brand Registry: Eligibility and Application Process for more information.
If the product you are listing has been confirmed to have no known UPC, EAN, ISBN, ASIN, or JAN code and if you are listing a unique selection, you may request a brand or SKU-level UPC exemption. Visit How to List Products That Do Not Have a GTIN for eligibility information.
For fitment-related products such as Automotive and Power Sports, visit The Automotive and Powersports Part Finder to learn more about how to provide fitment data to Amazon. You may apply for brand or SKU-level UPC exemptions to list these types of products.
If you are listing print-on-demand or customizable products, you might be eligible to join the Amazon Custom program, which allows you to offer customized products. Using Amazon Custom to list your products can improve your discoverability among buyers, improve your search relevance and listing efficiency, and also help you manage your inventory better. Additionally, one product with multiple designs requires only a single UPC exemption. Visit Amazon Custom for more information.
The following prohibited practices are misuses of variations (also known as parent-child relationships). They create a negative customer experience and can result in your ASIN creation or selling privileges being temporarily or permanently removed:
