How to fix: Missing or incorrect GTIN

Add a brand and either a GTIN or MPN. If this product is one-of-a-kind or vintage, you don’t need to add an identifier

Why this issue is happening

One or more of the values you’ve submitted for unique product identifier (UPI) attributes are either missing or aren't recognized as a valid identifier. Depending on the country that you’re targeting and the Google product category of the product you’re showing, you may be required to provide unique product identifiers or to state that such identifiers don’t exist for that item.

How to fix your issue

For each product, provide the appropriate unique product identifier values ( GTIN [gtin] , MPN [mpn] , and brand [brand] ) based on our UPI guidelines . You may also need to add a value for the identifier exists [identifier_exists] attribute.

Note:If your product is one-of-a-kind or vintage, you don’t need to add an identifier. You may state that such identifiers don’t exist for that item by specifying ‘false’ in identifier exists attribute.
