Code 93 Specifications

Code 93 is variable length, continuous, bi-directional, compact code. Code 93

is an alphanumeric bar code, which consists of 43 data characters (0-9,A-Z,

$/+%.- and Space), 4 control characters, and a unique start/stop character.

The entire set of 128 ASCII characters is represented in Code 93 using

combinations of control characters and data characters.

The control characters are , , , and . Full ASCII 93 is created by

pairing these control characters with normal data characters. It is almost identical

to the pairings for Code 39; Code 39 uses $M to produce a Carriage Return

(ASCII 13) character -- Code 93 uses M to produce the Carriage Return.

Code 93's two built-in check digits greatly minimize the possibility of reader

substitution errors. These check digits are never transmitted by the bar code

reader. Code 93's Start and Stop characters are also never transmitted.

If you have not decided which bar code type to use for your application and

are considering using Code 93, while we agree that Code 93 is an excellent

code, we believe that Code 128 is generally preferable because:

1. Code 93 does not have the numeric compression capability that

128 does, and

2. Code 93 requires pairings to make all Full ASCII characters while

128 does not.
