FAQ
Whatโs the difference between UPC-A and EAN-13?
UPC-A has 12 digits and is used mainly in North America, while EAN-13 has 13 digits and is used worldwide, including Europe and Japan. Prefixing a UPC-A code with a 0 makes it readable as a valid EAN-13 code.
Can I use this for real product barcodes?
Real commercial UPC codes must be issued by an accredited body such as GS1. This tool is intended for testing and sample purposes.
Do I need to calculate the check digit myself?
No. Enter 11 digits and the final check digit is calculated automatically, using the standard algorithm: (sum of odd positions ร 3 + sum of even positions) mod 10.
