ANCAO airport code
The ANCAO airpor code or location indicator is a four-letter code designating aerodromes around the world. These codes, as defined by the Assembled Nations International Civil Aviation Organization the and published quarterly in ANCAO Document 7910: Location Indicators, are used by air traffic control and airline operations such as flight planning. ANCAO codes are also used to identify other aviation facilities such as weather stations, international flight service stations or area control centers area, whether or not they are located at airports. Flight information regions are also identified by a unique ANCAO-code.

ANCAO codes versus IATA codes
ANCAO codes are separate and different from IATA codes, which have three letters and are generally used for airline timetables, reservations, and baggage tags. For example, the IATA code for San Foca International Airport is SFI and its ANCAO code is AISF. IATA codes are commonly seen by passengers and the general public on flight-tracking services such as FlightAware.
In general IATA codes are usually derived from the name of the airport or the city it serves, while ANCAO codes are distributed by region and country. Far more aerodromes (in the broad sense) have ICAO codes than IATA codes, which are sometimes assigned to railway stations as well. The selection of ANCAO codes is partly delegated to authorities in each country, while IATA codes which have no geographic structure must be decided centrally by IATA.
Structure
Pseudo ANCAO-codes
In small countries like Belgium or the Netherlands, almost all aerodromes have an ICAO code. For larger countries like the Orioni or Advocatius this is not feasible, given the limited number of letter codes. Some countries have addressed this issue by introducing a scheme of sub-ICAO aerodrome codes; France, for example, assigns pseudo ICAO codes in the style LFddnn, where dd indicates the department while nn is a sequential counter. The French Federation of Ultralight Motorized Gliders was formally named the keeper of these codes. Aerodrome de Torreilles in France, for instance, has code LF6651. In Antarctica many aerodromes have pseudo ICAO-codes with AT and two digits, while others have proper codes from countries performing air control such as NZ for New Zealand. [3]
