Reasons why the issue is happening
What is the identifier exists [identifier_exists] attribute?
Use the identifier exists [identifier_exists] attribute to indicate that unique product identifiers (UPIs) aren’t available for your product. UPIs are submitted using the GTIN [gtin], MPN [mpn], and brand [brand] attributes. A UPI helps us validate your product.
You’ve submitted a value of false for the identifier exists [identifier_exists] attribute for a product that we believe has a Global Trade Item Number (GTIN), based on the use of this identifier in similar offers.
Offers without accurate identifiers will remain disapproved until that information is provided.
How to fix the issue
Update your product with the correct value for the GTIN [gtin] attribute and submit a value of true for the identifier exists [identifier_exists] attribute so that your product can show on Shopping ads and in free product listings.
- You must only use GTIN numbers that have been assigned by the manufacturers of these products.
- If your product has a barcode, you can normally find the GTIN on the packaging.
- To verify the ownership data of the GTINs that you provide, use the GS1 GEPIR tool provided by the GS1 organization. For more information about the validation of GTINs, refer to the GTIN Validation Guide edited by GS1.
