King Fahd International Airport

King Fahd International Airport carries the IATA code DMM — the three letters printed on boarding passes and baggage tags — and the ICAO code OEDF, used in flight plans and by air traffic control. It serves Ad Dammam, Saudi Arabia.

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.
