Amazon Error: Product ID Matching Error

The "Product ID Matching Error" on Amazon indicates a discrepancy between the product identifier entered by the seller and the existing data in Amazon's catalog. This error occurs during the listing process when Amazon’s system cannot match the provided product ID with any existing product in its database. Product identifiers like UPC (Universal Product Code), EAN (European Article Number), and ISBN (International Standard Book Number) are crucial for Amazon’s cataloging system to ensure product accuracy and prevent duplicates.

Common Causes of Product ID Matching Error:

1. Incorrect Product ID: The provided product identifier might be incorrect or contain typographical errors.
2. Non-Registered ID: The product identifier may not be registered with the appropriate authorities (e.g., GS1 for UPCs).
3. Mismatch with Existing Data: The product ID might not match the existing product information in Amazon’s catalog, possibly due to incorrect or outdated data.
4. Duplicate IDs: Using a product identifier that has been used for another product, leading to conflicts in Amazon’s system.
5. Format Issues: Incorrect formatting of the product ID, such as missing digits or incorrect characters.

To resolve the "Product ID Matching Error," follow these steps:

1. Verify the Product ID:
   • Double-check the product identifier for any typographical errors or missing digits. Use barcode scanners or verification tools to ensure accuracy.
2. Ensure Proper Registration:
   • Confirm that the product identifier is properly registered with the appropriate authorities (e.g., GS1 for UPCs). Non-registered or unofficial IDs are often not recognized by Amazon.
3. Match with Existing Products:
   • Search Amazon’s catalog using the product identifier to see if the product already exists. Ensure that the product ID matches the product details accurately (title, brand, category).
4. Correct Formatting Issues:
   • Ensure the product ID is formatted correctly. For instance, UPCs should have 12 digits, EANs should have 13 digits, and ISBNs should have 10 or 13 digits.
5. Use Unique Identifiers:
   • Ensure that the product identifier is unique to the specific product you are listing. Avoid using recycled or duplicate IDs.
6. Consult Manufacturer or Supplier:
   • If you are a reseller, contact the product’s manufacturer or supplier to verify the correct product identifier.
7. Update Product Information:
   • If the product ID does not match due to outdated or incorrect information, update the product listing with accurate details.
8. Apply for GTIN Exemption:
   • If the product does not have a standard identifier, apply for a GTIN (Global Trade Item Number) exemption through Amazon’s Seller Central. Provide necessary documentation to support the exemption request.
9. Contact Amazon Seller Support:
   • If you cannot resolve the issue, contact Amazon Seller Support for assistance. Provide detailed information about the error and the steps you’ve taken to address it.
