GS1 DataMatrix generator

Data Matrix with GS1 data: GTIN, batch, expiry date — on medicines and products.

Data

“(AI)value” pairs, e.g. (01)09501234543215(17)271231(10)A1.

Width, mm Check a code

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.

You can check this code on the home page: by camera, from an image or a screenshot.
