AIX-ID Lookup
Resolve any AIX-ID — or find an AIX-ID by FAA site number, ICAO code, SEC CIK, or ticker symbol.
The AirIndex Facility Identifier System (AIX-ID) is permissively licensed — free to look up, free to cite, free to use commercially. The lookup below resolves identifiers in real time from the live registry.
See the full AIX-ID methodology paper for the namespace, persistence rules, audit chain, and licensing details.
