How can I get a MPN/GTIN number for Amazon Associate products?

Topic summary

Issue: A Shopify store promoting Amazon Associate products is being denied by Google due to missing MPN/GTIN identifiers, and Amazon reportedly doesn’t provide these for affiliate listings.

Key terms:

  • GTIN: Global Trade Item Number used to uniquely identify products.
  • MPN: Manufacturer Part Number.
  • Google Merchant Center (GMC): Platform for submitting product feeds to appear in Google Shopping.

Advice shared:

  • Contact Amazon support to clarify availability of product identifiers for Associate-linked items.
  • In GMC, if GTIN/MPN/Brand are unavailable, set the attribute “identifier_exists” to “No” to indicate missing unique product identifiers and avoid disapproval.
  • Use GMC feed rules to apply “identifier_exists=No” across affected products.

Current status: No confirmation that the store was approved; guidance provided but no resolution reported.

Open questions:

  • Will Amazon supply GTIN/MPN for Associate products?
  • Does setting “identifier_exists=No” fully satisfy Google’s requirements for these listings in practice?

Seems like you are feeding products to Google Merchant Center.

Google Merchant Center product feed expects each product the appropriate unique product identifier values like GTIN, MPN, and Brand. If you don’t have the values, then you have to use the identifier exists [identifier_exists] attribute to indicate that the unique product identifiers (UPIs) are not available for your product.

identifier_exists is an attribute that tells Google that this product is missing identifiers, and this will prevent these products from being disapproved.

If these identifiers are not available, you have to set identifier_exists=No, otherwise set it to Yes.

You can use GMC feed rules to set the identifier_exists to “No”.
