How to look up an aircraft by ICAO hex or registration

Find an aircraft profile from its ICAO 24-bit hex code or tail number, then read flight history, routes, and airport visits on FlightDB.

An aircraft identity is usually either a registration (tail number, such as N12345 or 9M-XXX) or an ICAO 24-bit hex (Mode S address, such as A12345). FlightDB is built around those keys: search, open the profile, then read history instead of only a live map pin.

Search by registration or hex

  1. Open the search box in the FlightDB header, or go to the aircraft directory.
  2. Enter a tail number (with or without dashes) or the ICAO hex.
  3. Open the matching profile. The hex is the aircraft id in the URL, for example /flight/A0001A.

If you only have an operator or airport, browse the directory filters or an airport page and click through to the aircraft.

What the profile includes

  • Type, operator, country, and other registry fields
  • Recorded flight count, first and last flight, distance
  • Countries visited and activity by year
  • Airport visits and time on the ground

That is the difference versus Flightradar24 or FlightAware: those sites answer “where is it now?” FlightDB answers “what has this airframe been doing?” See the flight data website comparison for when to use which tool.

Look up from Claude or ChatGPT

If you want an assistant to resolve a hex or tail number, connect FlightDB MCP. The same aircraft search, history, and airport tools are available without copying values out of a live map.
