To sell a product available in the Amazon catalog, you need to match it to the existing ASIN. However, if your product is not in the Amazon catalog, you will have to create a new ASIN.
To protect the onsite shopping experience for our customers, we limit the number of 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 ASINs, we reserve the right to temporarily remove your ability to create new ASINs. If your ability to create new ASINs has been removed, you can continue to match your products against existing ASINs. We will reevaluate your status on a monthly basis.
If you think your ASIN creation privileges have been removed in error, please contact Seller Support.
Matching your products to existing products in the Amazon 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.
Creating a duplicate ASIN (that is, creating a new ASIN for a product that already exists in the catalog) is prohibited and can result in your ASIN creation or selling privileges being temporarily suspended or permanently removed.
The following prohibited practices are a misuse 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:
Adding children that are not true variations of the parent product. This includes adding incorrect variations to ASINs you’ve created.
Changing the parent product's detail page so it does not match the children
Adding multi-pack variations that aren’t manufacturer-created to an already existing parent
If you’ve created a multi-pack listing that is not directly sold by the manufacturer, you must match your listing to an identical multi-pack product detail page. If an identical multi-pack detail page doesn’t exist, you must create a new product detail page with its own unique UPC.
Adding multi-pack children by bundling two or more of the same manufacturer products, such as bundling two three-packs to create a package quantity of six. Multi-pack children must be packaged by the manufacturer. If a customer wants to buy two or more of the same product, they can select that quantity for purchase.
How are duplicates created?
Duplicates are most commonly created when one or more of the following happens:
You incorrectly use the UPC, EAN, ISBN, ASIN, or JAN from another product to identify your product.
You are a Brand Registry seller using an alternative key attribute to list your products. If you use multiple key attribute values to list the same product, a new ASIN will be created for each key attribute value.
You have received a product identifier exemption for a product that actually has a product identifier. Listing it with no identifier will create a duplicate.
Tips to help avoid creating duplicate ASINs
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:
Register your brand with Amazon
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.
Request a brand or SKU-level UPC exemption
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.
Provide fitment data to Amazon
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.
Register for Amazon Custom
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.
