Air Force Specialty Code

The Air Force Specialty Code (AFSC) is an alphanumeric code used by the United States Air Force to identify a specific job. Officer AFSCs consist of four characters and enlisted AFSCs consist of five characters. A letter prefix or suffix may be used with an AFSC when more specific identification of position requirements and individual qualifications is necessary. The AFSC is similar to the Military Occupational Specialty (MOS) used by the United States Army and the United States Marine Corps or enlisted ratings and USN officer designators and USCG officer specialities used by the United States Navy and the United States Coast Guard.

After the Air Force separated from the Army in 1947, it retained the Army's system of MOS occupation codes, modifying them in 1954. These were 5-digit codes; for example a maintenance data systems specialist was 39150 and a weather technician was 25170. In October 1993, the Air Force implemented a new system of AFSCs, aligning occupations with the forcewide restructuring that was implemented under Merrill McPeak. These reduced officer AFSCs from 216 to 123 and enlisted AFSCs from 203 to 176.

The enlisted AFSC consists of five alphanumeric characters:

For example, in the AFSC 1N371:

For some specialties, an alpha prefix is used to denote a special ability, skill, qualification or system designator not restricted to a single AFSC (such as "X" for an aircrew position). Additionally, an alpha suffix (a “shredout”) denotes positions associated with particular equipment or functions within a single specialty (an Afrikaans specialist in the Germanic linguist field would have an "E" shredout). Using the above example, the AFSC X1N371E would refer to a Germanic Cryptologic Linguist who is aircrew qualified and specializes in Afrikaans.
