(Redirected from ICAO airport code)The 'ICAO' (
IPA pronunciation: ) '
airport code' or 'location indicator' is a four-letter
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''.
The ICAO codes are used by
air traffic control and airline operations such as
flight planning. They are not the same as the
IATA codes encountered by the general public, which are used for
airline timetables,
reservations, and
baggage handling. ICAO codes are also used to identify other locations such as
weather stations, International
Flight Service Stations or
Area Control Centers, whether or not they are located at airports.
Unlike the IATA codes, the ICAO codes have a regional structure, are not duplicated and are comprehensive. In general, the first letter is allocated by continent and represents a country or group of countries within that continent. The second letter generally represents a country within that region, and the remaining two are used to identify each airport. The exception to this rule is larger countries that have single-letter country codes, where the remaining three letters identify the airport.
In the contiguous
United States and
Canada, most, but not all, airports have been assigned three-letter
IATA codes which are the same as their ICAO code without the leading K or C. e.g., YYC and CYYC (
Calgary International Airport,
Calgary, Alberta), IAD and KIAD (
Dulles International Airport,
Chantilly, Virginia). These codes are not to be confused with radio or television
call signs, even though both countries use four-letter call signs starting with those letters.
However, because Alaska, Hawaii and other United States territories have their own 2-letter ICAO prefix, the situation there is similar to other smaller countries and the ICAO code of their airports is typically different from its corresponding 3-letter FAA/IATA identifier. For example,
Hilo International Airport (PHTO vs ITO) and
Juneau International Airport (PAJN vs JNU).
'ZZZZ' is a special code which is used when no ICAO code exists for the airport and is normally used in
Flight plans.
