The SID number is assigned to an individual the first time an arrest fingerprint card is received at the CIB. The number remains with that person as long as the CIB retains the file.
Some electronic fingerprint submission devices or record management systems may not be able to accommodate state identification numbers exceeding eight characters (WI999999). In those instances, the preceding WI should be removed from the state identification number and only the seven digit number be submitted (1000020).
