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. In general, the following policies apply to protect the customer shopping experience:
Amazon may limit the number of new listings that you may create depending on your sales history, listing creation history, and other factors.
You may not create a new ASIN for a product that already exists in Amazon’s catalog.
You may only create accurate variation relationships between products which are fundamentally related to one another. Newer versions or models of the same product are invalid variations.
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
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:
Changing the product’s detail page (parent or child) to become fundamentally different from the original product listed.
Changing the parent product's detail page so it does not match the children.
Adding incorrect child variations that are not true variations of the parent product. This includes but is not limited to:
Adding products that are fundamentally different from the parent ASIN
Adding products images and/or names that are that are fundamentally different from the parent ASIN.
Adding products that are newer versions or models of the parent ASIN.
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, that is, 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.
ASIN creation policy
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.
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 not belonging to the product (such as from another
product) to identify the product you are selling.
You introduce distinct
UPCs, EANs, ISBNs, or JANs for identical products. For example:
You assign a product a new UPC or EAN in each Amazon marketplace where you sell the
You assign a new UPC or EAN for compatible products such as a laptop charger that is
compatible with multiple laptops.
You are an Amazon 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 without an
identifier will create a duplicate.
