Fix issues with a GTIN or unique product identifier
GTINs and other unique product identifiers (UPIs) uniquely distinguish products you are selling and help match search queries with your offers.
Some products don’t have a GTIN assigned, and so you don’t need to submit one. However, if the product does have a GTIN assigned and you don’t submit it, then the product could be disapproved.
Use the information below to determine how you should submit GTIN or other UPI information for your product.
