What is a UPC code?
A UPC (Universal Product Code) is a 12-digit number used on products sold in the United States and Canada. The UPC code lookup process matches that number against global product databases to return title, manufacturer, and marketplace listings.
UPC code lookup for Amazon sellers
Listing on Amazon requires matching supplier UPCs to ASINs. Our UPC code lookup returns parent/child ASIN trees, variation attributes, and sales rank — so you can validate wholesale lists before you buy inventory.
Frequently asked questions
Where do I find the UPC code on a product?
Look beneath the barcode on the package — it is the 12-digit number. Some labels show UPC and EAN together.
Does one UPC code map to multiple ASINs?
Sometimes. Multipacks, bundles, and regional listings can share a UPC. EcomSource returns all known ASIN matches.
