ICAO

ICAO: International Civil Aviation Organization is a specialized agency of the United Nations that supports and regulates aviation and navigation across the globe. Its main responsibility is to oversee and ensure the safety and security of international air travel. ICAO also performs essential functions such as assigning codes for aircraft type, airline, and airport. These codes are crucial for efficient and accurate communication within the aviation industry. ICAO airline codes are made up of three letters, while ICAO airport codes consist of four letters, both of which differ from IATA codes.
