Amazon Error: 18564 Error 18564: The asin __was identified as a duplicate to other high rank asin

The "Error 18564: The ASIN __was identified as a duplicate to other high rank ASIN" indicates that Amazon's systems have flagged your product listing because it matches another existing ASIN that has a higher sales rank or visibility. Amazon aims to maintain a clean and organized catalog by reducing duplicate listings, ensuring customers have a clear and accurate selection of products. This error often arises from sellers inadvertently creating new listings for products that are already available in Amazon’s catalog.

Common Causes:

1. Existing Listings: The product you are listing is already available under a different ASIN.
2. Catalog Data Matching: Amazon’s automated systems identified the product details (such as title, brand, and specifications) as matching another ASIN.
3. Duplicate Entries: Unintentionally creating multiple listings for the same product.
4. Incorrect ASIN Assignment: Assigning a new ASIN to a product that should be listed under an existing ASIN.

To resolve the "Error 18564: The ASIN __was identified as a duplicate to other high rank ASIN" on Amazon, follow these steps:

1. Identify the Duplicate ASIN:
   • Log in to Amazon Seller Central and navigate to the suppressed ASIN B012345678.
   • Review any notifications, alerts, or error messages from Amazon to identify the high-ranking ASIN that your product duplicates.
2. Review Product Details:
   • Compare the product details of the suppressed ASIN with the high-ranking ASIN. Ensure that the title, description, brand, specifications, and images match.
   • Verify if the products are indeed identical or if there are any significant differences.
3. Merge Listings:
   • If the products are identical, consider merging your listing with the existing high-ranking ASIN. This can be done by listing your inventory under the existing ASIN rather than creating a new one.
   • Update your product details to match the existing high-ranking ASIN, ensuring consistency across listings.
4. Update Your Inventory:
   • If you decide to merge listings, update your inventory in Amazon Seller Central to reflect the correct ASIN.
   • Remove the duplicate listing (B012345678) to avoid further confusion and maintain a clean catalog.
5. Correct ASIN Assignment:
   • Ensure that future listings are assigned to the correct ASIN by thoroughly checking the catalog before creating new listings.
   • Use Amazon’s ASIN Lookup tool to verify if a product already exists in the catalog.
6. Prevent Duplicate Listings:
   • Implement procedures to prevent duplicate listings in the future. This includes training your team to check for existing ASINs before creating new listings.
   • Use inventory management software to track your listings and avoid duplications.
7. Monitor Listing Compliance:
   • Continuously monitor your product listings for compliance with Amazon’s policies. Regularly review listings and make updates as needed to maintain compliance.
   • Use Amazon’s tools and reports to keep track of your listings and address any issues promptly.
8. Contact Amazon Support:
   • If you encounter any issues during the resolution process or need further assistance, contact Amazon Seller Support. Provide detailed information about the error, the steps you have taken, and any relevant documentation.
