Code 49 generator

Code 49 — the first stacked barcode.

Data

Latin letters, digits and common symbols, up to 49 characters.

Width, mm Check a code

Beta: the code follows the standard but hasn’t been verified by an independent reader — test it with your scanner.

PDF and print use the chosen width. Print at 100% scale, not “fit to page”.

How to print a code that scans

Print at 100% scale — the 100 mm ruler on the print sheet shows if the printer resized it.
The white margins are already in the file: don’t crop them or put text or a frame right next to the code.
Dark code on a light background. Test red ink, glossy film and clear labels with a proof first.
Don’t shrink a barcode too much: EAN-13 and UPC-A at standard size are about 37 mm (1.47 in) wide.
Before a print run, print one sheet and test it with the scanner people will actually use.
“Ready” on this site means an independent software reader decoded the code. It is not an ISO or GS1 certificate.

Our checker can’t read this code type yet: browser-based scanners don’t support it. Test it with a dedicated scanner. Other codes can be checked on the home page.
