Everything you need to know about FAA N-numbers and aircraft registration.
An N-number is the unique registration number assigned to aircraft registered in the United States. It always begins with the letter 'N' followed by up to 5 alphanumeric characters. For example, N12345 or N1AB. The FAA requires all U.S. civil aircraft to display this number.
To register an N-number, you need to: 1) Search for an available N-number using Tailfinder, 2) Reserve it on the FAA website for $10, 3) Submit FAA Form 8050-1 (Aircraft Registration Application), and 4) Pay the $5 registration fee. The process typically takes 6-8 weeks.
Reserving an N-number costs $10 and is valid for 1 year. The actual aircraft registration fee is $5. So the total cost to register is $15. Renewal of registration costs $5 every 3 years.
You can request any available N-number that follows FAA format rules: it must start with 'N', be 2-6 characters total, and can only contain numbers and letters (except I and O, which are not allowed to avoid confusion with 1 and 0).
An N-number reservation is valid for 1 year from the date of reservation. You must complete the aircraft registration within that time, or the reservation expires and the number becomes available again.
An 'assigned' N-number is currently registered to an aircraft. It cannot be reserved or used until the current registration is cancelled or expires. An 'available' N-number has no current registration and can be reserved.
Yes, N-numbers can be transferred between aircraft you own, or released back to the FAA. You'll need to submit the appropriate FAA forms and may need to re-register the new aircraft with that number.
The FAA allows several N-number formats: N followed by 1-5 numbers (N1, N12345), or N followed by 1-4 numbers and 1-2 letters (N1A, N12AB). Shorter numbers and those with letters are often considered more desirable and memorable.
Tailfinder syncs with the official FAA aircraft registry database regularly to ensure you're seeing current availability. However, the FAA updates their registry on their own schedule, so there may be a short delay between FAA changes and our data.

A good N-number is short, memorable, and easy to communicate over the radio. Many pilots prefer numbers that match their initials, have a personal meaning, or are easy to say in aviation phonetics. Shorter N-numbers (like N1A or N99) are especially sought after because they're quicker to read back during radio communications.
Yes, the FAA maintains a public aircraft registry where you can look up the registered owner of any assigned N-number. Visit registry.faa.gov and search by N-number to see registration details including owner name, aircraft make and model, and registration status. Tailfinder shows availability status but does not display owner information.
When an aircraft registration is cancelled or an N-number is deregistered, the number typically becomes available for reservation again after a waiting period. The FAA may hold certain numbers temporarily before releasing them. Once released, anyone can reserve the number for $10 through the FAA. Tailfinder's daily data sync will reflect these changes as they appear in the FAA registry.
A 'reserved' N-number has been claimed by someone for $10 but is not yet registered to a specific aircraft. Reservations last 1 year and can be renewed. An 'assigned' N-number is actively registered to a specific aircraft and is in use. Neither reserved nor assigned N-numbers are available for new registration.
The fastest way to check N-number availability is to search on Tailfinder, which shows real-time availability status synced daily from the FAA registry. Simply type the number you're interested in (with or without the 'N' prefix) and you'll instantly see if it's available, reserved, or assigned. You can also check directly on the FAA's website at registry.faa.gov.
