# About Codabar barcodes

> Learn what Codabar barcodes are, which characters they allow, and the start and stop character rules you need to follow in B-Coder Pro.

![Example of a Codabar barcode reading A23342453D](https://mintcdn.com/taltech-bdc45607/90dE9DPyCdPJ5zuC/images/barcode-codabar-100dpi.png?fit=max\&auto=format\&n=90dE9DPyCdPJ5zuC\&q=85\&s=b6327a2799e57865e5a8dede570b53dd)

CodaBar is a variable-length symbology that can encode up to 20 characters: 0123456789-\$:/.+ABCD. It is widely used in libraries, blood banks and air parcel services. A, B, C and D are used only as start and stop characters, so the first and last digits of a CodaBar message must be one of these, and the body should not contain them.

[B-Coder Pro](https://www.taltech.com/b-coder-pro/) will allow any length of CodaBar message as long as it contains valid characters and starts and ends with a valid start/stop character. If you use lower case letters for A, B, C, or D, B-Coder Pro will convert them to upper case.
