Changing your aircraft's tail number
Your aircraft doesn't have to keep the number it came with. Owners change tail numbers for initials, a company brand, a lucky digit, or just something shorter over the radio. The FAA process is routine — the key is doing the steps in the right order.
Step 1: secure the new number
First, the number you want has to be yours to use. If it's open, reserve it with the FAA for $10 — it holds in your name for a year, renewable. If it's taken, check its status with an N-number lookup: a reserved number has a public expiration date and can be watched until it lapses, or transferred from the current holder. Nothing else in the process starts until the number is reserved to you.
Step 2: file the assignment (Form 8050-64)
With the number reserved, you ask the FAA to assign it to your aircraft using Form 8050-64, Assignment of Special Registration Numbers. The FAA processes the change against your aircraft's registration record and returns the authorization that lets you place the new number on the aircraft. Processing is measured in weeks, not days — file before you book the paint shop.
Step 3: make it physical
Once authorized, the aircraft gets its new identity: repaint or re-vinyl the tail markings to FAA size and placement specs, update the fireproof data plate if applicable, and carry the updated registration paperwork in the aircraft. Coordinate with your maintenance shop — they have done this before.
Step 4: the downstream updates
The registration is also your call sign and your identity in a dozen databases. After the change, update the transponder's registered number, your ELT beacon registration, insurance policy, and anything else keyed to the old number. If the old number is worth keeping — short, meaningful, or resellable — reserve it in your name rather than letting it fall back into the pool.

Frequently asked questions
How much does it cost to change a tail number?
The FAA side is cheap: $10 to reserve the new number, plus the special registration paperwork. The real cost is the physical change — repainting or re-applying vinyl numbers typically runs a few hundred to a couple thousand dollars depending on the aircraft and shop. If you buy a premium number from a current holder, add that purchase price.
How long does a tail number change take?
Plan on several weeks end to end: the reservation is quick, FAA processing of the assignment paperwork typically takes a few weeks, and then the physical repaint and record updates happen on your schedule. The new number cannot be used until the FAA authorizes it.
Can I keep my old tail number?
Yes — when the new number is assigned, you can ask to reserve your old number so it stays in your name (handy if it has sentimental value or resale value) instead of releasing it back to the open pool.
Do I need to change my radio call sign too?
Your call sign is your registration, so it changes with the tail number automatically. Remember the downstream updates: transponder registration, ELT registration with its beacon database, insurance paperwork, and any hangar or flight-tracking accounts keyed to the old number.
Can I put a reserved number on an aircraft I'm buying?
Yes, and it is common to line the two up together: reserve the number first (no aircraft required), then have it assigned during the registration of the newly purchased aircraft so it never flies under an interim number.
