To create an ASIN, go through the process as outlined in our Add a Product tool. To sell a product available in the Amazon catalog, 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 customer shopping experience, we limit the creation of new ASINs for a brand enrolled in Brand Registry, by sellers who are not associated with the brand owner.
If you encounter the following error message, it is because you are not associated with the brand owner and therefore restricted from creating new ASINs for the brand. You may still seek approval to create the new ASIN if you can show that it is an authentic product of the brand, for which no ASIN exists yet. Providing all the necessary information on the first contact will reduce the time it will take for your request to be reviewed.

You may not create new ASINs for this brand. However, you are free to add offers to any existing ASIN for this brand (listing limitations may apply). Please review our ASIN creation policy for more information.
If you believe the product you want to sell is not already listed in the Amazon catalog and should be listed as a new ASIN, contact Selling Partner Support and mention error code 5461. Before contacting Selling Partner Support, review the ASIN Creation Policy and confirm your product is not already listed on the catalog.
When contacting Selling Partner Support, provide the following information:
Brand name, UPC (or EAN/JAN), and part number (or model/style number) can be found on a purchase order or invoice from the manufacturer or distributor from which your product was purchased. Some information may be available directly from the product packaging or through the manufacturer’s catalog or website.
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 re-evaluate your status on a weekly basis.
If you think your listing creation privileges have been removed in error, please contact Seller Support.
Variations are sets of products that are related to one another. Good variation relationship listings allow buyers to compare and choose products based on different attributes such as size, color, or other characteristics from the available options on a single product detail page. For more information, see Variation Relationships Overview.
The following prohibited practices are misuses of variations, either of the parent ASIN or in parent-child relationships. These practices create a negative customer experience and can result in your ASIN creation or selling privileges being temporarily or permanently removed:
Creating a new ASIN when the 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. For more information, refer to Potential duplicates, Amazon brand name policy, and guidance on how to obtain a GTIN exemption.
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 About Amazon Brand Registry 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 can 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 Automotive & Powersports Part Finder and Fitment Data 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.
