Amazon Error: Missing Product Identifiers

The "Missing Product Identifiers" error on Amazon indicates that a product listing is lacking one or more essential identifiers required by Amazon’s catalog system. Product identifiers such as UPCs (Universal Product Codes), EANs (European Article Numbers), ISBNs (International Standard Book Numbers), and ASINs (Amazon Standard Identification Numbers) are crucial for accurately cataloging products, ensuring correct categorization, and facilitating search functionality. These identifiers help maintain a uniform and organized product database, making it easier for customers to find and purchase products.

Common Causes of Missing Product Identifiers Error:

1. Lack of Product Identifier: The product does not have a UPC, EAN, ISBN, or other necessary identifier.
2. Incorrect or Incomplete Entry: The identifier might be incorrectly entered, incomplete, or missing from the listing.
3. Non-Compliance with Category Requirements: Certain categories may have specific requirements for product identifiers that have not been met.
4. New or Unique Products: For new or custom products, identifiers may not yet be assigned or required exemptions have not been obtained.
5. Bulk Listing Errors: When using bulk listing tools, required identifiers might be omitted or incorrectly formatted.

To resolve the "Missing Product Identifiers" error, follow these steps:

1. Identify Required Identifiers:
   • Determine which identifiers are required for your product category. Amazon typically requires UPC, EAN, ISBN, or ASIN for most products.
2. Obtain Product Identifiers:
   • If your product does not have an identifier, obtain one. Purchase UPCs or EANs from authorized sources such as GS1. For books, obtain an ISBN from an official ISBN agency.
   • For products without standard identifiers, apply for a GTIN exemption through Amazon’s Seller Central if eligible.
3. Ensure Accurate Entry:
   • Verify that the product identifiers are accurately entered in the listing. Double-check for any typographical errors or missing digits.
   • Use barcode scanners or verification tools to confirm the correctness of the identifiers.
4. Use Existing ASINs:
   • If your product is already listed on Amazon, use the existing ASIN for your listing. Search Amazon’s catalog to find the correct ASIN.
5. Category-Specific Requirements:
   • Check the category-specific requirements to ensure compliance. Some categories might have unique rules for product identifiers that need to be followed.
6. Update Bulk Listings:
   • When using bulk listing tools, ensure that all required fields for product identifiers are filled out correctly. Use Amazon’s inventory file templates which highlight necessary fields.
7. Contact the Manufacturer:
   • If you are a reseller, contact the product’s manufacturer or supplier to obtain the correct product identifiers.
8. Consult Amazon Support:
   • If you have verified all the information and still encounter issues, contact Amazon Seller Support for assistance. Provide them with details about the error and the steps you have taken to resolve it.
