Frequently asked questions

Is my barcode data uploaded anywhere?

No. Barcodes are drawn with the bwip-js library directly in your browser, so the text you encode never leaves this page — nothing is uploaded or stored.

Which barcode formats are supported?

CODE128 (the best all-rounder — text, numbers and symbols), CODE39 (industrial and logistics labels), EAN-13 (12–13 digit retail product codes) and UPC-A (11–12 digit retail codes).

What should I enter for EAN-13 or UPC codes?

Digits only: 12 or 13 digits for EAN-13, 11 or 12 digits for UPC. If you enter the code without its check digit (12 or 11 digits), the check digit is computed for you automatically.
