UPC-A

UPC-A Barcode Generator

Q: Where does the UPC number come from?

A genuine retail number comes from a GS1-registered company prefix. This tool only turns a number into a barcode — it does not issue numbers.

Q: Should I enter 11 or 12 digits?

Either. Enter the first 11 and the 12th check digit is added automatically; enter a full 12 and the last digit is verified.
