I didn’t find a good check digit calculator for code 128

I was able to print and scan the 3 of 9 bar codes with the scanner. After some reading I found out that the check digit for the 3 of 9 is ‘*’ but for code 128 it is something else. I tried to find out what the check digits are for the code 128 font but did not have success. Looks like there are different types and there is a formula or methodology to calculate the check digit. I didn’t find a good check digit calculator for code 128

Best Answer

Are you attempting to calculate the check digit for Code 128 or the start/stop characters for Code 128?

The font encoders will calculate the Mod103 check digit. However, there is an option to manually calculate the check digit.

Encoding the data with a font encoder will also add the start/stop characters.

Start A character is Ë
Start B character is Ì
Start C character is Í
Stop Character is Î
