Valid UPCs
We verify the authenticity of product UPCs by checking the GS1 database. UPCs that do not match the information provided by GS1 will be considered invalid. Obtain your UPCs directly from GS1 (and not from other third parties selling UPC licenses) to ensure the appropriate information is reflected in the GS1 database.
Important: All invalid product UPC listings will be removed and may result in your ASIN creation or selling privileges being temporarily or permanently removed. For more information on licensing UPCs from GS1, see the GS1 standard website.
