Carlos Concha Torres International Airport

Carlos Concha Torres International Airport carries the IATA code ESM — the three letters printed on boarding passes and baggage tags — and the ICAO code SETN, used in flight plans and by air traffic control. It serves Tachina, Ecuador.

IATA codes are assigned by the International Air Transport Association for passenger-facing use; the four-letter ICAO code encodes region and country and belongs to the operational side of aviation.
