Choose the right format
Pick a symbology for the system that will read your code. A barcode image is not a product number: use an EAN or UPC number you already own or have been assigned.
EAN-13
For an existing 13-digit retail identifier. The last digit is a check digit and the tool checks it before drawing the image.
UPC-A
For an existing 12-digit identifier commonly used in North America. The last digit is checked; this tool does not issue UPC numbers.
Need a different output?
Make a sheet of the same scannable label for printing, or create a compact two-dimensional Data Matrix code instead.
Print barcode labels
Set a label size and quantity, then print a US Letter sheet of the same barcode.
Generate Data Matrix
Encode text into a compact ECC 200 Data Matrix symbol and download it as an image.
Before you print
Use a dark code on a light background, leave its margins intact, and scan a test print with the equipment that will read it.
