Frequently Asked Questions

What barcode type for a URL?

Use QR code — barcodes like Code 128 work for text but are much wider for the same content.

Will it scan reliably?

Yes — barcodes are rendered at the standard 2D module size. Printed at 100% on a regular printer, any standard scanner reads them.

Can I include a check digit?

EAN-13 and UPC-A auto-calculate the check digit. Code 128 has a built-in checksum. Code 39 supports optional checksums.
