IATA Airport Code
An IATA airport code, also known as an IATA location identifier, IATA station code, or simply a location identifier, is a three-character alphanumeric 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 assignment of these codes is governed by IATA Resolution 763, and it is administered by the IATA's headquarters in Montreal, Canada. The codes are published semi-annually in the IATA Airline Coding Directory. IATA provides codes for airport handling entities, and for certain 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, and , is available. However, many railway administrations have their own list of codes f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
