Aircraft Registration & Tail Number Lookup
Look up civilian aircraft tail numbers (N-numbers, G-, C-, D-, F-, VH-). Decode airframe specs, engine models, ICAO 24-bit transponder hex codes.

About this tool
How to use it
- Enter a civil aircraft tail number (e.g. N104UA, G-EZTD, C-FMWY, D-AIXP, VH-VGF) into the primary lookup field.
- Click 'Decode Registration' or press Enter to resolve registration records and ICAO Mode-S transponder codes.
- Inspect airframe specifications, manufacturer, model, serial number, engine configuration, and operator details.
- Click the ICAO Hex Code or Tail Number copy buttons to copy formatted transponder addresses for flight tracking tools.
Why it matters
Aviation spotters, pilots, and aerospace analysts need fast, direct tail number decoding without intrusive subscription paywalls. Instant client-side ICAO transponder computation provides reliable identification with zero telemetry.
When to use it
Use this lookup when identifying aircraft overhead, checking civil airworthiness registration status, configuring ADS-B radar receiver feeds, or verifying airframe serial numbers.
Good to know
Decodes national prefix authorities according to ICAO Annex 7 and computes mathematical US FAA N-number to 24-bit binary Mode-S hex address mappings in real time.
Common questions
How does an aircraft tail number prefix indicate its country of registry?
Under the Chicago Convention on International Civil Aviation (ICAO Annex 7), national prefixes are globally standardized: 'N' for United States, 'G-' for United Kingdom, 'C-' for Canada, 'D-' for Germany, 'F-' for France, and 'VH-' for Australia.
What is an ICAO 24-bit Mode S transponder hex code?
Every civilian aircraft possesses a unique 24-bit binary address (represented as a 6-character hexadecimal string, e.g. A01844) broadcast by its ADS-B transponder to ground radar and satellite flight trackers.
Can US FAA N-numbers be mathematically converted to ICAO hex addresses?
Yes. The FAA uses an official deterministic algorithmic mapping between N-number strings and their assigned 24-bit binary hex addresses within the block A00001–ADF7C7.
Can aircraft change their tail registration numbers?
Yes. When an aircraft is exported to another country or sold to an owner who requests a custom vanity registration, the tail number is updated and a new national ICAO hex address is assigned.
Is my aircraft lookup history recorded or tracked?
No. All lookups and algorithmic conversions run 100% locally within your client browser. We never collect or store your search history.
