Frequently Asked Questions
Genuinely calculated — using the real EAN-13 checksum algorithm (alternating weight-1/weight-3 digit sum, modulo 10), the same formula real barcode scanners validate against.
No — it only outputs the 13-digit number. It links to real barcode-image generators (bwip-js.metafloor.com, barcode.tec-it.com) to render the actual scannable image from that number.
The remaining digits are padded with zeros before the check digit is calculated — for a real product, you'd need your actual assigned GS1 manufacturer/product code, not padding.
No — the check digit calculation happens entirely in your browser.
