How to generate and validate UPC-A
UPC-A is a 12-digit retail symbol commonly used in North America. Enter 11 digits to calculate its check digit or enter all 12 to verify a number. QRFoundry validates the number locally, but it does not issue company prefixes or confirm that a product number is registered to a particular business.
Nothing you enter or upload is sent to a server, saved, or shared.
Use it in three steps
- Enter the 11 data digits or a complete 12-digit UPC.
- Review the calculated or validated check digit.
- Export PNG, SVG, or PDF and scan a printed sample.
