Q: Which barcode format should I choose?

Match the format to your IDs and scanner

Code 128 supports printable ASCII in this generator, including uppercase and lowercase letters. It is a useful default for internal identifiers. Code 39 uses uppercase letters, numbers, spaces and the symbols - . $ / + %. The tool rejects unsupported characters rather than silently changing your ID.

Confirm that the intended scanner reads your selected format. Long values need more horizontal space, so the generator checks density at the chosen physical size. If a value does not fit, shorten it, select a larger label or use a QR code for longer content.
