ICAO Document 8585. Designators For Aircraft Operating Agencies, Aeronautical Authorities and Services

The official technical reference manual Documento OACI 8585 Designadores for Aircraft Operating Agencies, Aeronautical Authorities and Services (ICAO Doc 8585) serves as the indispensable global source unifying civil aviation telecommunications. Published directly by the International Civil Aviation Organization (ICAO / OACI), this comprehensive publication compiles three-letter designators (3LD) and official radiotelephony callsigns for aircraft operating agencies, civil aviation authorities, and air traffic service providers worldwide. It is a critical guide ensuring every commercial pilot operates within a standardized environment.

Mandatory for global flight operations since October 25, 1987, this standard guarantees that flight crews, air traffic controllers, and automated data networks utilize unified terminology during operational message transmissions. Standardized coding remains essential for managing flight plans under PANS-ATM (Doc 4444) rules and communicating across global fixed networks like AFTN and AMHS in modern air transport.
