Very simple way to clear it up.
92-9000 is a military
registration in laypersons terms but officially it is a "serial" number. Hopefully that does not confuse even more! Military planes dont have true registration numbers, since they are all to be registered to the military. That particular number implies the order and year in which the plane was ordered by the DoD.
so it goes in with all registrations, in the reg box.
A code would be - in the case of military planes which we are talking about here - such things as "ANG", "KS
" (on Air Force, they have 2 letters which stand for the base, "KS
" is Keesler AFB). The code identifies the base or unit that the plane is with in military while in civilian it identifies the fleet number for the plane. The C130 that are based at BNA all have the code "ANG" because they belong to the Air national Guard.
