The system has evolved so that no two airports share the same three-letter code. The codes are formed by ensuring that it is original and no other airport is using it. Codes can be developed based on the name of the city, the name of the airport, or something relevant to the area.
How are ICAO airport codes assigned?
ICAO code consists of 4 letters. Certain classifications among countries and regions are used in creating these codes. The first letter stands for the region in which the airport is located, the second is for the country. The other two letters are generally given in order.
Do some airports have the same code name?
Two airports within the same region cannot have the same first and second, or second and third letters. The idea is to avoid confusion between DCA and IAD, IAH and HOU, DFW and DAL, etc.
What is the difference between ICAO and IATA airport codes?
ICAO codes are the next most widely recognized codes. While IATA codes specifically support the airline travel industry, ICAO codes more broadly support international flight operations regardless of the type of operation (to include general and business aviation).
What does ICAO classifies airports based on?
Explanation: The ICAO classification system is based on geometric designs broadly. It mainly considers 2 things for its classification – length of the runway and on basis of wing span and outer main gear wheel span.
Are ICAO codes usually derived from the name of the airport or city it serves?
ICAO codes versus IATA codesIn 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. Far more aerodromes (in the broad sense) have ICAO codes than IATA codes, which are sometimes assigned to railway stations as well.
Can two airports have the same ICAO code?
What is an example of an ICAO airport code?
Typical examples are London Heathrow (ICAO: EGLL) and London Gatwick (ICAO: EGKK). This is different from an IATA code (International Air Transport Association), which is also used to identify airports but is used for the commercial side of the airline industry such as ticketing and baggage handling.
What is the relationship between IATA and ICAO?
Both IATA and ICAO are international organizations that oversee civil aviation operations. However, the IATA generally supports the airline industry, while the ICAO provides global standards for air transport operations. Furthermore, the IATA uses a different list of airport codes that passengers can easily relate to.
How does ICAO name airports?
The first one or two letters of the ICAO code indicate the country; the remaining letters identify the airport. ICAO codes are used partly for geographical context. For example, the ICAO code for Heathrow International Airport in London, is EGLL, with its first letters reflecting that it is based in the United Kingdom.

What is an example of an ICAO code?
They are defined by the International Civil Aviation Organisation (ICAO) and are used by Air Traffic Control (ATC) and airline operations for flight planning. Typical examples are London Heathrow (ICAO: EGLL) and London Gatwick (ICAO: EGKK).
