Tail number lookup: how to look up any aircraft
A tail number lookup answers the question every spotter, buyer, and curious neighbor eventually asks: what exactly is this aircraft, and whose is it? The data is public — aircraft registration is a matter of record in nearly every country — but it's scattered across registries, accident databases, and historical files that don't talk to each other.
This guide covers what a lookup can tell you, where the official sources fall short, and how to get the complete picture — owner, history, and incidents — from a single search.
What a tail number lookup returns
For a US aircraft, the FAA's registry ties an N-number to the airframe's core identity and its registered owner. A complete lookup — the kind SpotterLog runs automatically when you log a sighting — layers several public sources on top of each other:
- Aircraft identity: manufacturer, model, serial number, and year
- Registered owner: the person, company, or trust the aircraft is registered to, with location
- Registration status: valid, expired, deregistered, or exported — with the dates
- Airworthiness details: certificate class and dates
- Accident and incident history: NTSB records tied to the airframe
- Position data: where the aircraft was last seen broadcasting on ADS-B
The catch: official sources only show you 'now'
The FAA registry is a snapshot. It tells you who owns the aircraft today — not the four owners before that, not the tail number the airframe wore in a previous life, and not the incident it had under that old registration. Aircraft get re-registered surprisingly often, and each re-registration is a place where history can quietly detach from the airframe.
That's the gap SpotterLog's data platform was built to close. It maintains ownership and registration history over time — a CarFax-style trail for aircraft — and cross-references NTSB records across an airframe's previous identities. When you look up a tail number, you're seeing the aircraft's whole story, not just its current chapter.
Running a lookup in SpotterLog
There are two ways in. The deliberate way: search a registration directly and read the record. The spotter's way: photograph an aircraft, key the tail number, and the lookup happens as a side effect of logging the sighting — the full record attaches itself to your collection automatically.
Either way, the aircraft is now on your radar permanently. If it changes owners next year, gets deregistered, or shows up in an NTSB report, SpotterLog notifies you. A lookup with a memory beats a lookup you'll have to remember to re-run.
International registrations
Non-US aircraft follow the same principle with their own registries — Transport Canada for C- registrations, the UK CAA for G-, and so on. Coverage and detail vary by country; owner information in particular is public in some registries and withheld in others. SpotterLog's database includes international registration data, so foreign-registered aircraft you spot still resolve to type and identity.
Frequently asked questions
Is tail number lookup free?+
Yes. The FAA registry is free to search, and SpotterLog includes registry lookups in its free tier — along with the sighting log that attaches each lookup to your own photos.
Can I look up who owns a plane by its tail number?+
For US aircraft, yes — the registered owner is public record. Note that some aircraft are registered to trusts or LLCs, which can take an extra step to interpret. SpotterLog shows the ownership trail over time, not just the current name.
Can I look up an aircraft's accident history by tail number?+
Yes. NTSB accident and incident records are public and searchable by registration. The subtlety is that accidents follow the airframe, not the tail number — if the aircraft was re-registered after an incident, a naive search misses it. SpotterLog cross-references history across registration changes.
What's the difference between a tail number and an N-number?+
An N-number is simply a US tail number — every American civil registration starts with N. "Tail number" is the universal term covering every country's registrations.
Put it into practice
SpotterLog is free to start — photograph an aircraft, and the app identifies it, logs the sighting, and pulls its registry, owner, and incident history automatically.
