Common Errors
Missing Product Identifiers

Error Description

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.

Error Solution

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.

Pro Tip

Optimizing Product Identifiers to Prevent Errors:

  1. Maintain an Organized Inventory Database:
    • Create and maintain a comprehensive inventory database that includes all necessary product identifiers for each item. This ensures that all listings are complete and accurate.
  2. Automate Identifier Management:
    • Use inventory management software that integrates with Amazon to automatically manage and validate product identifiers. This can help in reducing manual errors and ensuring consistency.
  3. Regularly Update Product Information:
    • Keep your product information up-to-date. Ensure that any new products added to your inventory have the correct identifiers before listing them on Amazon.
  4. Leverage GS1 for Authentic Identifiers:
    • Purchase UPCs or EANs directly from GS1 to ensure they are legitimate and unique. Avoid buying cheap or unofficial codes which might not be recognized by Amazon.
  5. Implement Pre-listing Validation:
    • Use pre-listing validation tools to check for missing or incorrect identifiers before submitting your listings. These tools can highlight potential issues and prevent errors.
  6. Train Your Team:
    • Provide regular training for your listing team on the importance of product identifiers and how to correctly enter them. Keeping the team informed can reduce errors significantly.
  7. Utilize Amazon’s Listing Tools:
    • Take advantage of Amazon’s listing tools and resources, such as the Product Classifier and Listing Quality Dashboard, to ensure that your listings meet all requirements.
  8. Engage with Amazon Seller Communities:
    • Participate in Amazon seller forums and communities to stay informed about best practices and common issues related to product identifiers. Engaging with other sellers can provide valuable insights and tips.
  9. Develop a Contingency Plan:
    • Have a contingency plan in place for handling products without standard identifiers. This could include applying for GTIN exemptions or contacting suppliers for necessary information.
  10. Audit Listings Regularly:
    • Conduct regular audits of your listings to ensure that all required product identifiers are present and correct. This proactive approach can help catch and correct issues before they lead to errors.

By adhering to Amazon’s guidelines, maintaining accurate and complete product information, and implementing proactive measures, sellers can avoid the "Missing Product Identifiers" error, ensuring a smooth and efficient listing process on Amazon.
