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 Codes (MOS Codes) used by the United States Army and the United States Marine Corps or enlisted ratings and USN officer designators and Naval Officer Billet Classifications (NOBCs) used by the United States Navy and enlisted ratings and USCG officer specialties used by the United States Coast Guard. The United States Space Force equivalent is known as the Space Force Specialty Code (SFSC). History 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 force wide restructuring that was implemented under Merrill McPeak. These reduced officer AFSCs from 216 to 123 and enlisted AFSCs from 203 to 176. Enlisted AFSCs The enlisted AFSC consists of five alphanumeric characters: Career group (Numerical) Operations Logistics & Maintenance Support Medical Professional Acquisition Special Investigations Special Duty Identifiers, typically used for Airmen chosen for specialized jobs Reporting Identifiers, typically used for Airmen in transitive status: trainees, awaiting retraining, prisoner, etc. And occasionally for Airmen chosen for specialized jobs.
