United States Air Force Tail Codes

Tail Codes are markings usually on the vertical stabilizer of U.S. military aircraft that help to identify the aircraft's unit and/or base assignment and other information.
A tail code is not the same as the Air Force Serial Number, Navy Bureau Number, aircraft registration number, or Buzz Number.
Since 1993, all Air Force units, including Air Force Reserve and Air National Guard, utilize this system.
This video explains the markings on the tail structure, and provides examples of how the tail codes have been implemented on various U.S. Air Force aircraft.
