What Is an UPC Barcode Generator?

UPC-A is the 12-digit barcode found on retail products throughout North America. It's structurally equivalent to EAN-13 with an implicit leading 0. UPC-E compresses a UPC-A code into 8 digits for products too small for the full symbol — the scanner expands it back to UPC-A at read time, so a single product can carry either symbol.

This tool accepts 11 digits for UPC-A and computes the check digit (or 12 digits and validates), and 6/7/8 digits for UPC-E with the same logic. Errors are flagged inline so you can fix and retry without losing input.

The symbol is rendered locally as SVG or PNG — your digits never leave the browser. To register a code with major retailers you'll still need a GS1-assigned company prefix; for internal SKU tracking you can use any digits.
