GS1 Composite CC-A generator

GS1 Composite CC-A — an EAN-13 with a small 2D block on top for the batch or expiry date.

An EAN-13 number, a | and GS1 pairs, e.g. 9501234543215|(10)A1.

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”.

The generator draws a code from your number, but it doesn’t issue GS1 numbers or confirm your right to use them.

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.
