The ICAO airport code or location indicator is a four-letter code designating aerodromes around the world. These codes, as defined by the International Civil Aviation Organization and published quarterly in ICAO Document 7910: Location Indicators , are used by air traffic control and airline operations such as flight planning . ICAO codes are also used to identify other aviation facilities such as weather stations , international flight service stations or area control centers , whether or not they are located at airports. Flight information regions are also identified by a unique ICAO-code.

810-459: The same year. ICAO codes are separate and different from IATA codes , the latter of which have three letters and are generally used for airline timetables , reservations, and baggage tags. For example, the IATA code for London 's Heathrow Airport is LHR and its ICAO code is EGLL. IATA codes are commonly seen by passengers and the general public on flight-tracking services such as FlightAware . In general IATA codes are usually derived from
840-526: The style LFddnn , where dd indicates the department while nn is a sequential counter. The French Federation of Ultralight Motorized Gliders was formally named the keeper of these codes. Aerodrome de Torreilles in France, for instance, has code LF6651. In Antarctica many aerodromes have pseudo ICAO-codes with AT and two digits, while others have proper codes from countries performing air control such as NZ for New Zealand . FlightAware FlightAware
870-515: The two airports share runways and ground and air control facilities. In small countries like Belgium or the Netherlands, almost all aerodromes have an ICAO code. For larger countries like the UK or Germany this is not feasible, given the limited number of letter codes. Some countries have addressed this issue by introducing a scheme of sub-ICAO aerodrome codes; France, for example, assigns pseudo ICAO codes in
900-691: Was assigned both LLJR (its Israeli persona) as well as OJJR (its Jordanian persona), but the airport itself fell into disuse. In the contiguous United States and Canada, many airports have ICAO codes that are simply copies of their three-letter IATA codes, with the geographical prefix added on (e.g., YEG and CYEG both refer to Edmonton International Airport , while IAD and KIAD both refer to Washington Dulles International Airport ). This similarity does not extend to Alaska (PAxx), Hawaii (PHxx), or U.S. territories. Kahului Airport on Maui , for instance, has an IATA code of OGG and an ICAO code of PHOG. ICAO airport codes do not begin with I or J or X or Q, though
