Note: To print the Code 93 space character, use the "=" character instead of a space. The space character will produce a space and not a barcode. The space character can be printed before and after the barcode to ensure the proper quiet zone.

Code 93 Barcode Check Character Calculations

The check character is positioned after the data characters and just before the stop character. To determine the value of a Code 93 check character, use the following steps:

Reference the table above to obtain the value of all data characters.
Assign a weighting to each data character.
- The first check character is referred to as "C" and is a modulo 47 sum of the data character values and weighting values. These increase from right to left, with the last data character first. The range for weighting "C" is from 1-20, therefore, after 20 this value is reset to 1.
- The second check character is referred to as "K" and is also a modulo 47 sum of the data character values and weighting values. These also increase from right to left, with the "C" check character first. The range for weighting "K" is from 1-15, therefore, after 15 this value is reset to 1.
For check characters "C" and "K"; multiply the character values by their weights for the data characters.
Add these all together, divide by 47 and obtain the remainder.
Use the table above to locate the character that has the value of the remainder, use this as the check character

Example: Finding The Check Characters

DATA = C O D E 9 3 
Data Values = 12 24 13 14 38 9 3 
C Weights = 7 6 5 4 3 2 1 
K Weights = 8 7 6 5 4 3 2 1

To Calculate C:
(1*3)+(2*9)+(3*38)+(4*14)+(5*13)+(6*24)+(7*12)=484
484 / 47 = 10 remainder 14
C = E
To Calculate K:(1*14)+(2*3)+(3*9)+(4*38)+(5*14)+(6*13)+(7*24)+(8*12)=611
611 / 47 = 13 remainder 0
K = 0

Example: Encoding The Code 93 Barcode

To create a barcode containing "CODE 93" as the data to encode, select the appropriate Code 93 font and enter (CODE=93E0).
