Universal Product Code
Universal Product Code (UPC) is a 12-digit barcode standard, issued through GS1, used to identify retail products in North America. It is one format of the broader GTIN.
Why it matters for ecommerce brands
Amazon and most US retailers require valid GS1 barcodes. Warehouses scan UPCs to confirm the right item is picked.
Common questions
- Do I need a UPC to sell on Amazon?
- Amazon generally requires a GS1-issued product ID such as a UPC for most new listings, though brands enrolled in Brand Registry or certain categories can request an exemption. Codes bought from unofficial resellers may be rejected.
