How airport codes are determined?

Since the code contains only three letters, the possible combinations are limited and consequently the IATA codes are not unique in some cases, with the same code used to designate two different airports. Therefore, the ICAO codes were created because aviation requires a unique designation for airports.

ICAO code consists of 4 letters. Certain classifications among countries and regions are used in creating these codes. The first letter stands for the region in which the airport is located, the second is for the country. The other two letters are generally given in order.

IATA codes are three-letter codes used by a non-governmental trade organization to efficiently identify airports, airlines, and flight paths for consumers.
