N-number availability: how to check available and reserved FAA numbers
Use the FAA N-Number Availability Inquiry to check a proposed mark. A missing Aerovidence aircraft result does not mean that the number is available. Only the FAA can process a reservation or assignment.

Check available N-numbers with the FAA
The FAA links its availability search separately from assigned and reserved N-number inquiries. Open the official availability service below; it supports trailing characters and a starting and ending range. Follow the service’s input instructions and keep the result with the date you checked it.
- Decide whether you are researching an existing aircraft or choosing a proposed registration mark.
- For a proposed mark, open the FAA N-Number Availability Inquiry and use its search fields.
- Read the returned result and the FAA availability disclaimer before proceeding.
- Recheck through the FAA when preparing a request; do not treat a saved result as a reservation.

Availability can change while a request is processed
The FAA warns that daily reservation and assignment processing can change whether a number remains available. Its inquiry page states that data updates each Federal working day at midnight. An availability result is therefore a dated observation, not an approval, a held number or a promise that a later request will succeed.
| What you found | The next check |
|---|---|
| A number appears available in the FAA service | Read the disclaimer and use the official reservation process if you wish to request it. |
| An assigned or reserved N-number record | Read its exact status; do not treat it as an available mark. |
| No aircraft match in Aerovidence | Check the separate FAA availability service. A missing local match proves neither availability nor reservation. |
| A correctly formatted mark | Formatting and availability are separate questions. |

Keep reservation, assignment and aircraft identity separate
The FAA distinguishes a reserved N-number from an aircraft registration and a pending number change. A reservation may concern a mark intended for later use. Read the official status and related dates before associating it with an aircraft; reservation dates and certificate expiration dates answer different questions.

Research an aircraft after confirming its assigned mark
When your purpose is to research an existing aircraft, compare manufacturer, model and serial number with its documents. Then use the free aircraft lookup for dated registration and covered events. Historical uses of the same N-number can concern another airframe. Aerovidence does not provide live availability, submit reservations or issue assignments.
