Service number
From Halopedia, the Halo wiki
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 appear to be different schemes for different people, so it is possible that there is a different service number format for UNSC Officers, enlisted men, and warrant officers.
Note that the service numbers of members of ONI and the Spartans are classified for security purposes.
