How to fix: Conflicting values: GTIN [gtin], brand [brand]

Use a globally valid GTIN that is related to the brand you submit

A custom icon for Merchant Center Classic Article Header.

Submit an internationally recognized, unique identifier that is related to the brand you submitted for this product.

The value you submitted for the GTIN [gtin] attribute isn’t associated with the value you submitted for the brand [brand] attribute for this product. You need to provide a GTIN value that is associated with the brand of this product.

To verify the ownership data of the GTINs that you provide for US brands, use the GS1 GEPIR tool provided by the GS1 organization. For more information about the validation of GTINs, refer to the GTIN Validation Guide.
