When attempting to create a new ASIN through Zentail, you may receive the following error message from Amazon:
Error Message: We have identified potential matches to the product you are trying to list in the Amazon catalog. Please search the Amazon catalog to check if there are existing ASINS for products you are trying to list. For more information, please review our ASIN Creation Policy at: https://sellercentral.amazon.com/gp/help/201844590. If your product is not listed in Amazon catalog and needs to be listed with a new ASIN, please contact Seller Support at https://sellercentral.amazon.com/hz/contact-us and include the error code and message you received.
The reason this error is occurring is because Amazon thinks this may be a duplicate ASIN. According to Amazon's knowledge base, 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 without an identifier will create a duplicate.
Tips to 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.
