What are the differences between the FAA, IATA, and ICAO airport codes?
• FAA codes are assigned by the Federal Aviation Administration to airports within the United States of America, including its possessions and territories. FAA codes for airports with scheduled airline operations consist of three letters. Other FAA airport codes consist of three or four alphanumeric characters. • IATA codes contain three letters and are assigned by the International Air Transport Association to airports around the world. For US airports with an IATA code, the code is the same as the FAA code. (However, a US airport which does not have an IATA code may have a three letter FAA code which is the same as the IATA code for a non-US airport. One such airport is CBG.) • ICAO location indicators consist of four letters and are assigned by the International Civil Aviation Organization and published in ICAO Document 7910. They, too, are assigned to airports worldwide.
