Real N-number
Open a current aircraft record
Jump straight into a live exact-N-number response with aircraft, engine, registration, identifier, freshness, and provenance fields.
Open N172SP →Open-source reference app
Explore the FAA aircraft registry through a developer API.
Look up an N-number, resolve ICAO24, inspect lifecycle evidence, or review recent observed FAA registry changes. Every data request uses the public Grizzly Bulls Aircraft Intelligence API through this application's server.
One-click examples
See the API working before you write any code.
These links run real requests through this application's server. No API key is sent to your browser, and the results come from the same public Aircraft Intelligence API contract available to developers.
ICAO24 resolution
Resolve a current Mode S address
Use the current ICAO24 / Mode S hex associated with the same preset aircraft and resolve it through the dedicated endpoint.
Resolve A12239 →Lifecycle evidence
Check an N-number across FAA states
See registered, reserved, deregistered, or unknown evidence with the explicit not-determined availability boundary.
Check N172SP status →Observed change feed
Inspect recent registry changes
Load a bounded recent observation window with reviewed event types and privacy-safe field diffs.
View recent changes →Bounded discovery
Browse Florida registrations
Run a real state-filtered registry query and click any returned N-number into its current record.
Browse Florida →Observed history
Inspect retained snapshots
See how the same N-number appears across retained FAA snapshots without treating observation windows as legal ownership dates.

A small app built like an API customer.
The repository has no aircraft database or FAA ingestion pipeline. The pages below use the same public API contract and Bearer-key authentication available to any developer.
Lookup
Exact N-number records
Explore a current U.S. aircraft registration by N-number with normalized aircraft, registration, engine, airworthiness, identifier, and source metadata.
Open lookup →ICAO24
Resolve Mode S hex
Resolve one exact six-digit ICAO24 / Mode S address to the matching current U.S. FAA registration.
Resolve ICAO24 →Lifecycle
N-number status evidence
Resolve an N-number across reviewed registered, reserved, deregistered, and unknown states without claiming that unknown means available.
Check N-number status →Changes
Recent observed changes
Inspect a bounded registry-wide stream of reviewed observation-time changes with privacy-safe before/after diffs.
View recent changes →Discover
Bounded registry search
Search the current registry by exact manufacturer, model, or registrant state using the same authenticated API available to developers.
Search registry →History
Observed registry changes
Inspect retained registration states and PII-free change events while keeping snapshot observation time distinct from legal or source-effective time.
View observed history →Deliberate boundaries
Useful without overstating the data.
- U.S. FAA registry data only
- API key stays on the server
- No owner-name reverse search
- No unfiltered registry walking or bulk export
- Exact ICAO24 lookup only; no ranges or live ADS-B positions
- Registration data is not proof of beneficial ownership
