Information About

Icao Airport Code




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 are larger countries that have single-letter country codes, where the remaining three letters identify the airport.

In the contiguous United States and Canada , most 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 ( Calgary International Airport , Calgary, Alberta ) and CYYC, IAD ( Dulles International Airport , Chantilly, Virginia ) and KIAD. These codes are not to be confused with radio Call Sign s, 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).
