Starfleet Serial Number

Starfleet identifies its officers and enlisted personnel with a serial number, which is used as their file number in Starfleet records.
==Formatting==
There are several prefixes:
*SC: Starfleet Command
*SE: Starfleet Engineering Corps
*SS: Starfleet Security
*SM: Starfleet Medical Academy
*SI: Starfleet Infantry
*SMC: Starfleet Marine Corps
*SP: Starfleet Support
*SO: Starfleet Operations
The next numbers indicate the graduating class if the person attended Starfleet Academy, and is three digits in length. After the dash, is the entrant number within a person's class, and finally, a three letter suffix indicating family name, given name and middle name as appropriate (prior to 2256, it represented MOS). That information is enough to uniquely identify practically any service member in Starfleet. 
Enlisted personnel all receive the prefix ESF (Enlisted Starfleet), which may be transferred to the commissioned prefix upon commissioning, but will have the prefix "E" on their permanent record to show the officer was once enlisted before getting a commission.
==Examples==
*James Kirk: SC094-0176CEC
*Jean Luc Picard: SC166-0215PJL
