Air Force officer service numbers
The first regulation of Air Force service numbers applied to numbers held by Air Force officers. In 1947, thousands of officers had automatically transferred from the Army Air Forces into the Air Force, with over a third of this number inactive members of the Officer Reserve Corps. The first Air Force officer service numbers ranged from 1 to 19,999 and were reserved for Regular Air Force officers who had "crossed over" to the United States Air Force.
A complication to early service number issuance was that some senior Air Force officers (such as Henry H. Arnold) choose to simply retain their Army service numbers and did not apply for a new Air Force service number. Thus, the earliest Air Force officer service number was #4 which was assigned to Hoyt Vandenberg; numbers one through three were apparently never issued.
After the initial issuance of the first Air Force officer service numbers, the service numbers were increased with the second range extending from 20 000 to 99 999. These numbers were set aside for past, present, and future Regular Air Force officers with this range being used from 1948 until the discontinuation of Air Force service numbers in 1969.
For a brief time in the 1950s until 1965, cadets at the United States Air Force Academy were assigned a special range of service numbers only for use while attending the Academy. These numbers ranged from 1 to approximately 7000 based on admission date to the Academy. These numbers were followed by the suffix "K" and were not part of the regular Air Force service number system.
The service numbers 100 000 to 1 799 999 were never used by the Air Force office corps to avoid repeating numbers already assigned to Army officers; the only Air Force officers who ever held these numbers were those who had received their commissions under the authority of the Army Air Forces. The next range of Air Force officer service numbers began at 1 800 000 and extended to 1 999 999; these numbers were assigned to former reserve officers of the Army Air Forces who were now members of the Air Force Reserve. The two million number range was never issued by the Air Force, to avoid repeating service numbers of the Army, with the next range beginning at 3 000 000 and extending to 3 999 999. These numbers were intended for all officers considered "Other Than Regular Air Force" (OTRAF) and were issued in chronological order by date of commission after 1948. Such numbers were normally preceded with a zero.
In 1969, when the Air Force discontinued service numbers, the officer cap of 3 999 999 had not yet been reached. Thus, there were never any higher Air Force officer service numbers created. After 1969, the Air Force converted to Social Security numbers for service member identification.
Air Force enlisted service numbers
Air Force enlisted service numbers were designed along Army lines with the very first Air Force personnel issued Army numbers between September 1947 and early 1948. By the spring of 1948, the Air Force has established its permanent enlisted service number system with the design mirroring Army numbers almost exactly. It was also a fundamental principle that no airman would be issued a duplicate service number or a service number already held by someone in the Army.
The very first Air Force service numbers were seen as "crossover" numbers from personnel who had been members of the Army Air Forces; the Air Force also used the Army's 8 000 000 to 8 999 999 service number series for female enlisted personnel. The nine million service numbers were never used by the Air Force with Regular Air Force enlisted personnel beginning with service numbers in the ten million range. This numbers extended from 10 000 000 to 10 999 999 and, like the Army, were used for Regular Air Force personnel who had enlisted from recruiting stations outside the United States.
The service number range of 11 000 000 to 19 000 000 was used by Regular Air Force in the same manner as the Army, in that these numbers were reserved for Regular Air Force personnel, who had enlisted from inside the United States, with the first two numbers a geographical code and the last six a personal identifier. The geographical codes for the Air Force were the same as the Army and recruiting stations had instructions to avoid repeat service numbers and to ensure that no service number was issued by both the Army and the Air Force.
The service numbers of 20 000 000 to 29 999 999 were used by the Air National Guard with the thirty and forty million service numbers never issued by the Air Force. Even so, many veteran Air Force personnel who had served in World War II carried these numbers over with them upon augmentation to the Air Force. Therefore, there were numerous cases of Air Force enlisted members holding 30 and 40 million service numbers.
The service numbers 50 000 000 to 59 999 999 were used by Air Force draftees between 1948 and 1966. These numbers were issued in the same manner as the Army using the same geographical codes for the first two numbers. As with other service numbers used by both the Army and the Air Force, procedures were in place to avoid repeat or duplicate numbers.
The last range of Air Force service numbers was the 60 million series extending from 60 000 000 to 69 999 999. These numbers were used from 1966 to 1969. Air Force enlisted service numbers were formally discontinued on July 1, 1969, and replaced with Social Security numbers.
Air Force prefix and suffix codes
Upon the creation of Air Force service numbers, the Air Force had no prefix codes for special situations but did create a series of suffix one letter codes to be used solely be officers. The original suffix letter codes were:
A: Used from 1948 to 1965 by male Regular Air Force officers
E: Used until 1965 by male Regular Air Force warrant officers
H: Used until 1965 by female Regular Air Force warrant officers
K: Used by cadets at the Air Force Academy
W: Used from 1948 to 1965 by female Regular Air Force officers
In the mid-1950s, the Air Force created several prefix codes intended to replace the suffix letters, although both prefixes and suffixes were still being used simultaneously in military service records. The 1950s prefix codes were as follows:
AA: Used by female personnel of the WAF
AD: Used by Aviation Cadets
AF: Used by male enlisted personnel
AO: Used by Air Force reserve officers
AR: Use by Air Force dieticians
AW: Used by Air Force warrant officers
In 1965, the Air Force standardized the prefix codes and created this final version.
FG: Used by officers, warrant officers and enlisted personnel of the Air National Guard
FR: Used by officers, warrant officers and enlisted personnel of the Regular Air Force
FT: Used by officers and warrant officers who had yet to be assigned an Air Force component
FV: Used by officers, warrant officers and enlisted personnel of the Air Force Reserve
Older prefix and suffix codes continued to survive until the formal disestablishment of Air Force service numbers in 1969. In addition, the prefix "FR" was frequently switched between a prefix and suffix. After the establishment of social security numbers as the primary means of personnel identification, many Regular Air Force personnel would annotate the prefix "FR" before their Social Security number; a practice which continues to this day.
Geographical Codes and Service Number distribution
State Geographical Codes were used as the first two numbers of an Air Force enlisted service number to indicate where an airman had either enlisted from or had been drafted. For instance, the service number "12 345 678" would have a geographical code of 12 and a personal identification number of 345,678. The Air Force used geographical codes for Regular Air Force personnel and personnel who were issued service numbers in the 50 million range. The Air Force did not actively assign any 30 million draft numbers (these were held only by Air Force personnel who had "crossed over" from the Army Air Forces) and the sixty million range was issued without regards to geographical regions. In all, a comparison of the state codes is as follows:
|State||Regular Air Force Codes||Air Force Draft Codes|
|Hawaii||10 1||50 0|
Within the Regular Air Force, the range of 11 000 000 to 19 999 999 was reserved for Regular Air Force personnel who had enlisted from within the United States; With the first two numbers a geographical code and the last six a personal identifier. This gave geographical recruiting areas 999,999 service numbers a piece to allocate to new recruits. Air Force regulations directed against repeating service numbers and allocated only a certain block of numbers for certain time periods of enlistments. Instructions were also in place that Air Force service members should not be assigned numbers already held by Regular Army soldiers. This resulted in the first 200,000 personal identifier numbers of each geographical code remaining un-issued, since these numbers had already been exhausted by assignments to Regular Army personnel. The breakdown of Regular Air Force service number assignments, from 1947 to the discontinuation of service numbers in 1969, was as follows:
|Geographical Code||Allocated Numbers
|11||142 501 - 188 000||188 001 - 384 000||384 000 - 999 999|
|12||242 001 - 321 000||321 001 - 614 900||614 901 - 999 999|
|13||197 501 - 299 700||299 701 - 705 500||705 501 - 999 999|
|14||204 501 - 300 770||300 771 - 745 000||745 001 - 999 999|
|15||201 001 - 280 500||280 501 - 639 615||639 616 - 999 999|
|16||201 501 - 307 000||307 001 - 683 100||683 101 - 999 999|
|17||183 501 - 254 500||254 501 - 592 940||592 941 - 999 999|
|18||247 101 - 546 000||546 001 - 607 725||607 726 - 999 999|
|19||235 501 - 420 000||420 001 - 597 661||597 662 - 999 999|
