International Civil Aviation Organization Airport Code
The ICAO ( /ˌaɪˌkeɪˈoʊ/, "I-K-O") airport code or location indicator is a four-character alphanumeric code designating each airport around the world. These codes are defined by the International Civil Aviation Organization, and published in ICAO Document 7910: Location Indicators.
ICAO codes are used by air traffic control and airline operations such as flight planning. They differ from IATA codes, which 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. Most travelers usually see the IATA code on baggage tags and tickets and the ICAO code on flight-tracking services such as FlightAware. In general IATA codes are usually derived from the name of the airport or the city it serves, while ICAO codes are distributed by region and country.
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.
