Codes for Airline and City in Aviation


Airport codes arose out of the convenience that the practice brought pilots for location identification in the 1930s. Initially, pilots in the United States used the two-letter code from the National Weather Service (NWS) for identifying cities.


The International Air Transport Association has assigned each airline a 2-letter code and each airport a 3-letter code. The reason why these codes are assigned is so that these codes can be used for identification in documents and communication systems. The three-letter code is determined by first ensuring that it's unique and not in use by any other entity. The code might be assigned based on the name of the airport, the name of the city, or some other meaningful and relevant identifier if those letters are already taken.


An IATA airport code, also known as an IATA location identifier, IATA station code or simply a location identifier  is a three-letter geocode designating many airports and metropolitan areas around the world defined by the International Air Transport Association (IATA). The characters prominently displayed on baggage tags attached at airport check-in desks are an example of a way these codes are used.


The IATA and ICAO aerodrome identification codes serve the same purpose. However, there is no relationship between them and they have some differences. Therefore, the ICAO codes were created because aviation requires a unique designation for airports.


The assignment of these codes is governed by IATA Resolution 763 and it is administered by the IATA's headquarters in Montreal. The codes are published semi-annually in the IATA Airline Coding Directory.


IATA provides codes for airport handling entities, and also for railway stations.


Alphabetical lists of airports sorted by IATA code are available. A list of railway station codes, shared in agreements between airlines and rail lines such as Amtrak, SNCF French Railways, and Deutsche Bahn, is available. However, many railway administrations have their own list of codes for their stations, such as the list of Amtrak station codes.


Airline and Location code provides an official source for codes assigned and approved by IATA.


The 2-letter code of an airline or identify to which airline a 2-letter code corresponds.


The 3-letter code of an airport location or identify which airport uses a particular code corresponds.
