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. We recommend obtaining 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 GSI standard website.
