About UPC-A Barcodes
UPC-A (Universal Product Code) is the standard 12-digit retail barcode used in the United States and Canada. Every product on a Walmart, Target, or grocery store shelf carries a UPC-A. The 12 digits encode the manufacturer (via a GS1 Company Prefix) and the specific product, with the final digit serving as a check digit for error detection.
Our UPC-A generator auto-calculates the check digit — enter 11 digits and the 12th fills in automatically per GS1 specifications. Bars include proper quiet zones (10x minimum on each side) for reliable scanning at retail checkout. Download as print-ready 300 DPI PNG or infinitely scalable SVG vector.
