The ICAO airport code on Wikipedia is used to uniquely identify aerodromes and heliports across the globe. Although it is not recognized by the public as much as the IATA airport code, the ICAO code is more widespread, and registers even heliports and small aerodromes.

The key icao=* has as its value a 4 character code that should be put on the main area of the aerodrome or airport (the area or node with the tag aeroway=aerodrome). It can also be used with heliports (aeroway=heliport) or helipads not associated with a heliport (aeroway=helipad).

Although this code usually is not displayed on the map, it may be searched for using Nominatim, besides the possibility of being used by other tools.

The ICAO code is hierarchically organized in regions of the globe, and it changes its prefix accordingly. This kind of information can be used when doing automated quality assurance checks.
