Developed in 1977, Code 11 is a discrete symbology that uses high-density numerical encoding. The most common implementation of the barcode is for the labeling of telecommunications components. The barcode format is not as prevalent as it once was and remains for software compatibility.
Encoding
Code 11 can encode the following 10 characters and 1 special character:
10 digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
1 special character: -(dash)
Structure
Code 11 has the following structure:
Start character.
Encoded value.
Check digit C.
Check digit K (required if the encoded value is longer than 10 digits).
Stop character.
NOTE: The default check digit method is None.
Requirements
The height of the barcode must be at least 0.15 times the length of the barcode or 0.25 inches. You will need to choose the greater of the two measurements, whichever is greater.
Toolkit will automatically calculate and apply one or two check digits, based on the amount of digits in the encoded value. The barcode is not self-checking, as printing defects can alter one character into another character very easily.
