How to buy a custom N-number
A custom N-number — the tail number painted on an aircraft — is the aviation equivalent of a vanity license plate. This guide explains how FAA N-number reservations work, how a reserved number is transferred from one owner to another, and exactly what it costs and takes.
What is an N-number?
Every aircraft registered in the United States wears an N-number (also called a registration number or tail number): the letter N followed by one to five characters. The first character after the N must be a digit 1–9, and the letters I and O are never used because they look like 1 and 0. That format leaves a finite supply of short, clean, and memorable combinations — which is why the good ones are worth something.
Reserving vs. buying a number
Anyone can reserve an available N-number directly with the FAA for $10 per year, renewable indefinitely. The catch is that the desirable numbers are almost never available — they are already reserved, held, or on aircraft. That is where buying comes in: you purchase a number someone has already reserved, and they transfer the reservation to you.
How an N-number transfer works
The FAA supports a direct owner-to-owner transfer of a reserved number through a signed Relinquish-and-Transfer Letter. The process is standard and well established:
- The current holder signs a letter relinquishing the reservation and naming you as the new holder.
- You sign the same letter to accept the transfer.
- The letter is mailed to the FAA Aircraft Registration Branch (AFS-750) in Oklahoma City with the transfer fee (about $10–$20).
- The FAA processes it — usually 2–4 weeks — and the reservation is now in your name. Because it is directed to you by name, no one else can claim it during processing.
When you eventually put the number on an actual aircraft, you file FAA Form 8050-64 (Assignment of Special Registration Numbers) — but that is a later, separate step you only take when the airplane is ready.
What makes a number valuable
Scarcity drives price. Shorter is rarer: two-character numbers (N7A) are the crown jewels, followed by three-character numbers. Beyond length, buyers pay premiums for repeating digits (N888), sequences (N123), round numbers (N500), and personal meaning — initials, birth years, or a state code like N37TX for a Texas pilot.

Frequently asked questions
How much does a custom N-number cost?
The FAA charges $10 to reserve a special N-number for one year. A memorable or premium number bought from a reseller costs more — from around $150 for a clean mid-tier number up to several thousand dollars for short (three-character) or vanity numbers — because someone has already reserved it and is transferring it to you.
How long does an N-number transfer take?
The FAA typically processes a Relinquish-and-Transfer Letter in about 2–4 weeks. The reservation is directed to you by name, so it does not go back into the open pool while it is being processed — no one else can grab it in the meantime.
Do I need an aircraft to reserve an N-number?
No. You can reserve or buy an N-number with no aircraft at all. It stays reserved in your name (renewable yearly for $10) until you are ready to assign it to an aircraft, at which point you file FAA Form 8050-64.
What makes an N-number valuable?
Shorter is rarer and more valuable: two- and three-character numbers (like N7A or N88) are the most sought-after. Repeating digits (N888), sequences (N123), round numbers (N500), and personal initials or state codes (N37TX) also command a premium.
Can any N-number be reserved?
It must fit the FAA format: the letter N followed by one to five characters, the first of which is a digit 1–9, and it cannot use the letters I or O (too easily confused with 1 and 0). It also has to be currently available — not assigned to an aircraft or reserved by someone else.
