Code 39 is by far the most popular bar code symbology. It’s used for ID, inventory, and tracking. Why? Because the Code 39 character set includes both letters and numbers, the input string can be of variable length, and the bar code symbol itself can vary widely in height and width.

The C39Tools font package includes 27 different Code 39 fonts. Switching between the various fonts allows you to change the width and density of a bar code without changing its height. C39Tools also includes an OCR-B font for the optional human-readable characters above or below the bar code itself.
