Code 128
Code 128 is variable length and encodes the full 128 ASCII character set. Each character is
represented by 11 modules that can be one of four bar widths. Code 128 is the most easily read code
with the highest message integrity due to several separate message check routines. Of all the common
linear symbologies, Code 128 is the most flexible. It supports both alpha and numeric characters easily,
has the highest number of characters per inch, and is variable length.
Code 128 is widely used in the shipping industry.
The Code 128 character set includes the digits 0-9, the letters A-Z (upper and lower case), and all
standard ASCII symbols and control codes. The codes are divided into three character sets: A, B, and
C.
• Character Set A - Contains capital letters, control characters and digits.
• Character Set B - Contains all printable characters.
• Character Set C - Contains only numbers and the FNC1 character.
Code 128 Example
A special version of
Code 128 called GS1 (formerly known as UCC/EAN 128) is used extensively
world wide in shipping and packaging industries.
Code 39
Code 39 is variable length and is the most frequently used symbology in industrial bar code systems
today. The principal feature is to encode messages using the full alphanumeric character set. Three of
the nine elements (bars) are wide and six elements are narrow.
Code 39 Extended (Full ASCII Code): Standard Code 39 contains only 43 characters (0-9, A-Z, $, /, %,
+). Code 39 can be extended to an 128 character symbology (full ASCII) by combining one of the
special characters ($, /, %, +) with a letter (A-Z) to form the characters that are not present in the
standard Code 39 symbology. For example, in standard Code 39 a lowercase "a" cannot be
represented. In Code 39 Full ASCII, however, "a" is represented as "+A".
