What is UPC-A used for?
UPC-A is the 12-digit retail barcode used at point of sale across the United States and Canada. The first digits identify the company prefix issued by GS1, the middle block identifies the individual product, and the final digit is a mathematically derived check digit that scanners use to confirm a clean read.
If you are selling a physical product through a US retailer, a marketplace listing that requires a GTIN, or your own POS system, UPC-A is almost always the symbology you need. This generator renders the bars and the human-readable number underneath, and calculates the check digit for you when you supply 11 digits.
