Code 39 (or Code 3 of 9) is the most common bar code in use for custom applications. It is popular because it:
Supports both text and numbers (A–Z, 0–9, +, -, ., and <space>)
Can be read by almost any barcode reader in its default configuration
Is one of the oldest of the modern barcodes
Code 39 is a variable-width bar code, and it can support any number of characters that the reader can scan.
It is used in many military and government specifications.
Code 39 bar codes are self checking and are not prone to substitution errors. They generally do not require checksums.
