Service Number

A Service Number is a numerical designation given to each member of the UNSC military as a means of identification. Note that some service numbers of members of ONI and the SPARTANs are classified for security purposes. 
== Formation ==
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. An example is the SN of Jerald Ander, who uses a previously unknown format of four numbers, followed by three numbers, followed by his initials and a further four number string. 
Colonial Military Administration servicemen were also assigned UNSC Service numbers. These numbers followed the standard ten digit format, though in every known case the two letters did not match the individual's initials.
== Counterparts ==
* UNSCMID Number: Appear to be used in conjunction with Service Numbers, however, the Service Number use is far more widespread than UNSCMID numbers.
*Civilian Identification Number: A number that is given to civilians.
