MSI Check Digits
With MSI symbols, one check digit is mandatory and always verified by the reader. The second check digit is
optional. If the MSI codes include two check digits, enable the verification of the second check digit by scanning the
bar code below.
See MSI Check Digit Algorithm on page 12-42 for the selection of second digit algorithms.

One MSI Check Digit
Two MSI Check Digits
NOTE Due to the construction of the MSI symbology, it is possible for a scan line covering only a portion of the
code to be interpreted as a complete scan, yielding less data than is actually encoded in the bar code. To
prevent this from happening, select specific lengths (MSI - One Discrete Length - Two Discrete
Lengths) for MSI applications.
