What is Codabar used for?
Codabar is a self-checking numeric symbology wrapped in a start and stop letter from A to D. It was designed to be printable on early dot-matrix and impact printers, which is why it took hold in libraries, blood banks, photo labs, and courier networks — and why so many of those systems still run on it decades later.
Each Codabar value carries its own structure, so it stays readable even on poor-quality print stock. Use it when an existing library management system, blood-product register, or shipping platform explicitly expects Codabar; for new projects Code 128 is the better default.
