Service number

A Service Number is a numerical designation given to each member of the UNSC military as a means of identification. Service numbers usually follow a ten-digit format followed by two letters that are sometimes the first and last initials of a person. There is no known exact format for Service Numbers, as some follow this format, while others do not. It appears that Service Numbers are used in conjunction with UNSCMID numbers, however Service Number use is far more widespread than UNSCMID numbers.

Note that the service numbers of members of ONI and the Spartans are classified for security purposes.
