Aircraft Registry Special Registration Numbers

Information about the formation of an N-Number is available. You can check the availability of N-Numbers on the Aircraft Registration Inquiry website. You can also request reservation of an N-Number online.

To request a reservation of an N-Number in writing you must:

  • choose at least five N-Numbers, listed in order of preference
  • include your:
    • name
    • mailing address
    • phone number
    • signature
    • title of the requester (if appropriate)
  • provide a $10 (U.S. funds) check or money order payable to the Federal Aviation Administration

Note: If a desired N-Number is in a hold or reserved status and shows an approaching purge date, the number, if not renewed by the holder, will become available at 12:00 a.m. Central time (by the server time shown on the web page) the day following the purge date. Requests for the number may then be filed through the online request web page, in our Public Document Rooms at 7:30 a.m., by U.S. Mail, or overnight courier service.
