Which format should I use for arbitrary text?

CODE128. It encodes any ASCII text and is the most flexible choice; EAN and UPC are only for fixed-length numeric product codes.

Do I need to add the check digit?

No. For EAN and UPC the check digit is calculated automatically from the digits you enter.

Every common 1D format

Create retail and logistics barcodes including CODE128 (any text), EAN-13 and EAN-8, UPC-A, CODE39 and ITF-14. The preview renders instantly and validates your input against each format's rules.

Valid check digits, automatically

Fixed-length formats like EAN and UPC require a check digit. The generator computes and appends it for you, and warns when a value has the wrong length or contains characters the format does not allow.

Sharp at any size

Download an SVG for crisp printing on labels and packaging at any scale, or a 2x PNG on a white background for quick embedding. Everything is generated locally, so product codes stay private.
