KCI-ID is needed for certain services such as K-Circle, K-Messages, and Kal-Drive. This ID will be a unique number setup by KCI to provide an alternative means of communicating other than the NIN which might reveal too much information to a person. KCI-IDs will be a 2 letter followed by 8 digits. This will make each number unique while still offering privacy. The NIN can also be used, and added as an alternative.
