Bar Code 3 of 9 Bar Code 3 of 9 example
Bar Code 3 of 9 was the first alpha-numeric bar code developed and is the most widely used (non-retail) bar code. It is a self checking, medium density, alpha-numeric bar code. To make a bar code you simply surround your data with the Start/Stop character (the *). The standard version encodes 43 characters: A-Z, 0-9, space, and -.$/+%. A Full ASCII version is available (provided your bar code reader supports it) that can encode the entire ASCII character set, but at the cost of print density. Bar codes can be of variable length and don't normally use a checksum (a few industries use an optional modulo 43 checksum).
  • Encodes: Only 43 characters: 0-9, A-Z, and space $%+-./
  • Length: Variable
  • Checksum: Optional

Since Bar Code 3 of 9 does not normally require a checksum you do not need a computer program to generate it. This means that as long as you only need to be able to use upper case letters and numbers, you can just type in Bar Code 3 of 9.
