ASIN Creation Policy

There are two cases when it comes to listing an item on Amazon

  1. The item exists on the Amazon catalog

  2. The item is new to the Amazon catalog

To sell a product that is 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 their customers, Amazon limits 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. Amazon 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, Amazon 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. And Amazon will reevaluate your status on a monthly basis.

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.

  • Changing the parent product's detail page so it does not match the children.

  • 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 code 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 UPC exemption for a product that has a UPC. Listing it with no identifier will create a duplicate.
