IATA Airport Code

Aviation Codes

Definition

A three-letter code assigned by the International Air Transport Association to identify airports and metropolitan areas worldwide. IATA codes are the most commonly used airport identifiers in commercial aviation and logistics (e.g., PVG for Shanghai Pudong, FRA for Frankfurt, LAX for Los Angeles). These codes appear on boarding passes, baggage tags, and air waybills. IATA codes are distinct from ICAO codes (4 letters) and are primarily designed for passenger and cargo ticketing systems.
