Code 11 is also known as
Code 11 Overview
Code 11 was developed as a high-density numeric-only symbology. The symbology is discrete and is able to encode the numbers 0 through 9, the dash symbol (-), and start/stop characters. It is used primarily in labeling telecommunications equipment. Code 11 is not terribly secure in that printing imperfections can quite easily convert one character into another valid character. Data integrity is obtained by using one, or sometimes two, check characters.
