Resident Identification Number

All residents are issued with a Resident Identification Number. Residents are commonly identified by the first five digits of this number, although Adam Bash says that full identification numbers are significantly longer.

The first two digits of this number are a prefix which identifies which location the resident is assigned to. On the rare occasions that a resident is reassigned to a different location, their resident identification number will also change.
