Free Online UPC Barcode Generator
A UPC barcode generator produces UPC-A (12-digit) and compressed UPC-E (8-digit) symbols — the North American retail standard — with the check digit auto-calculated.
Your data is processed entirely in your browser and never sent to any server.
Enter 11 digits (we compute the check) or 12 (we validate it).
How to Use This QR Tool
- Pick UPC-A or UPC-E in the format selector.
- Type the digits — UPC-A wants 11 or 12, UPC-E wants 6, 7, or 8.
- We auto-compute or validate the check digit and render the symbol.
- Click Download PNG or SVG to save the barcode.
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.
