What an FAA N number is and why you might search for one

An FAA N number (or tail number) is a unique identifier painted on the outside of every aircraft registered in the United States. It starts with the letter N followed by up to five characters — for example, N12345 or N987AB. The FAA assigns this number when an aircraft is first registered, and it stays with that aircraft for its entire life, even if it changes owners.

You might search for an N number to find out who owns a particular plane, check its maintenance history, look up accident records, verify that an aircraft is currently registered, or research a plane before buying one. The FAA keeps this information public because aircraft operate in shared airspace and the public has a legitimate interest in knowing about them.

Key Takeaways

  • The FAA N-Number Search tool on the official FAA website lets you search by tail number, owner name, or aircraft type at no cost.
  • Search results show the aircraft's current registration status, owner information, manufacturer details, and when the registration expires.
  • The FAA database updates regularly but may lag by a few days, so very recent registrations or changes might not appear when ready.
  • If you know only partial information — like the owner's name or the aircraft model — you can still search and narrow results from there.

Using the official FAA N-Number Search database

The FAA maintains a free, public database called the Aircraft Registration Inquiry at registry.faa.gov. This is the authoritative source for current registration information. You do not need to create an account or provide personal information to search.

On the search page, you have three main options. You can search by N number (the tail number itself), by owner name (the person or company that registered the aircraft), or by aircraft serial number (a manufacturer's ID separate from the N number). If you have the tail number, that is the fastest route — type it in and the database returns results in seconds.

The search results show the aircraft's current status (active, expired, or pending), the registered owner's name and address, the aircraft's manufacturer and model, the year it was built, the engine type, and the date the registration expires. This information is updated regularly, though changes can take a few days to appear in the public database.

What to do if you have only partial information

If you do not have the exact N number, you can still search by what you do know. Searching by owner name works well if you are trying to find out what aircraft a particular person or company owns. The database returns all aircraft registered to that owner, so you can then identify the specific plane you are looking for.

You can also search by aircraft type — for example, "Cessna 172" or "Piper Cherokee" — though this returns a very large list if the model is common. Narrowing by state (where the owner is located) helps reduce the results. If you know the aircraft's serial number from a bill of sale or inspection report, that is another way in.

Reading your search results

Once you get a result, the database shows you several pieces of information. The Registration Number is the N number. The Status tells you whether the registration is currently active, expired, or in some other state. An expired registration means the owner did not renew it, though the aircraft may still be flying under a temporary permit.

The Owner section lists the registered owner's name and mailing address. For privacy reasons, the FAA does not always show the owner's phone number or email, but the address is public. The Aircraft Information section shows the manufacturer (Cessna, Piper, Beechcraft, and so on), the model, the year manufactured, and the aircraft's serial number assigned by the maker.

The Engine Information section lists how many engines the aircraft has and what type. The Certification section shows what category the aircraft falls into — standard airworthiness, experimental, or other classifications. The Registration Expiration Date tells you when the owner must renew the registration to keep the aircraft legally registered.

Why the database might not show what you expect

The FAA database is public and regularly updated, but it is not real-time. If an aircraft was just registered or an owner recently changed, it can take several days for that information to appear in the search results. Similarly, if a registration was just renewed or expired, there may be a lag before the status updates.

Another reason a search might not return results: the N number might be inactive or the aircraft might be registered under a different number than you thought. If you are searching for an aircraft you saw flying, remember that you may have misread the number — tail numbers can be hard to read from the ground, especially on smaller planes.

If you are searching by owner name and get no results, the owner might be registered under a business name, a trust, or a holding company rather than a personal name. Trying variations of the name sometimes helps. If you still cannot find the aircraft, you can contact the FAA directly through their general inquiry line, though they may not provide information beyond what is in the public database.

Other places to find aircraft information

The FAA registry is the official source, but other websites compile and republish this same public data in different formats. Sites like FlightAware, ADS-B Exchange, and similar aviation tracking services pull FAA registration data and combine it with real-time flight tracking information. These sites can be useful if you want to see where an aircraft is currently flying, not just who owns it.

If you are researching an aircraft for purchase, you may also want to check the FAA's accident and incident database (part of the Aviation Safety Reporting System) to see whether that specific aircraft has been involved in any reported accidents or safety events. This is separate from the registration database but uses the same N number to search.

Frequently Asked Questions

Can I find out who owns a plane if I only saw it flying?

If you noted the tail number (N number) while watching it fly, yes — search that number in the FAA registry and you will see the registered owner's name and address. If you did not catch the exact number, you can try searching by aircraft type and location, though that may return many results.

Is the owner information in the FAA database always current?

The FAA updates the database regularly, but changes can take a few days to show up. If an aircraft was recently sold or the owner moved, the old information might still appear for a short time. The registration expiration date is usually accurate, but very recent renewals may lag slightly.

What does it mean if an aircraft's registration status is "expired"?

It means the owner did not renew the registration by the expiration date. The aircraft cannot legally fly until the registration is renewed. However, the FAA sometimes grants temporary permits that allow flying during the renewal process, so an expired registration does not always mean the plane is grounded.

Can I search by partial N number if I only remember part of it?

The FAA search tool works best with a complete N number, but you can try entering what you remember and see if it returns results. If that does not work, searching by owner name, aircraft type, or location may help you narrow down the possibilities and find the plane you are looking for.

Do I need to pay to search the FAA aircraft registry?

No. The FAA Aircraft Registration Inquiry database is free and open to the public. You do not need to create an account, provide payment information, or give personal details to search it.
