code

IATA LOCATION CODE = 3 letters, used by travel professionals, airlines, etc.. It's not necessarily an airport. It can also be a bus, rail or ferry station (as long as it used for commercial transportation). Any small airport can apply for a IATA code, usually upon request from a local company (airline or cargo operator) starting new commercial service.

Some IATA codes can also be used for several airports: For example, "NYC" which covers all airports serving New York City: JFK, LGA, EWR.


ICAO CODE = 4 letters, used by Civil Aviation Authorities, flight operations and pilots. Used exclusively for airports.

For St. Barths, it is TFFJ. So pilots entering St. Barths as a destination in their nav computer (GPS, RNAV, FMS...) are typing "TFFJ" and not "SBH".

Other ICAO codes for the Caribbean region:

SXM = TNCM
SFG = TFFG
STT = TIST
SJU = TJSJ
ANU = TAPA
SKB = TKPK
......

The first letter "T" is used across the Eastern Caribbean (the region). The Second letter usually refers to the country (F = France), then the last two letters usually refer to the airport, often in reference to the IATA code (SJ = San Juan).

In the Continental US, things are kept simple:

K + IATA CODE = ICAO CODE

For example: KJFK, KMIA, KBOS, KLAX


Last, airports with no commercial operations (private airstrips) do not necessarily have IATA/ICAO codes. Thousands of them are found across the US. The airport "identifier" is then an alphanumeric combination issued by the FAA, made of 3 to 5 characters.

Jumbolair airport (a.k.a the "John Travolta airport") located in Florida is identified as "17FL".
