About UPC-A

REFERENCE

UPC-A is the 12-digit Universal Product Code used for retail checkout across North America. It was the very first barcode adopted commercially and remains the dominant retail symbology in the US.

What a valid UPC-A looks like

  • Exactly 12 digits, numeric only, with a mod-10 check as the last digit.
  • The first digit is a number-system digit (0, 1, 6, 7, 8 are general retail).
  • Leave a quiet zone of at least 9 modules on the left and 9 on the right.
  • Do not print below 80% of nominal size.
