How do I report my stolen aircraft?

If enough time has passed that the return of the aircraft is no longer expected, the owner should write to the Aircraft Registration Branch requesting that the registration for this aircraft be canceled. The request should fully describe the aircraft, indicate the reason for cancellation, be signed in ink by the owner and show a title for the signer if appropriate.

Where do N-numbers come from?

The U.S. received the "N" as its nationality designator under the International Air Navigation Convention, held in 1919. The Convention prescribed an aircraft-marking scheme of a single letter indicating nationality followed by a hyphen and four identity letters (for example, G-REMS). The five letters together were to be the aircraft's radio call sign.
