This system became unmanageable for cities and towns without an NWS identifier, and the use of two letters allowed only a few hundred combinations; a three-letter system of airport codes was implemented. This system allowed for 17,576 permutations, assuming all letters can be used in conjunction with each other.The Location Identifier, a distinctive 3-letter code synonymous with the IATA code, ascertains precise airport identification within aviation and logistics domains. Consider JFK, emblematic of New York's renowned John F. Kennedy International Airport.The three-letter code is determined by first ensuring that it's unique and not in use by any other entity.

The only non-Contracting States are the Holy See and Liechtenstein.
Why is it called YYC : Why does YYC stand for Calgary Airport – Quora. When the first Canadian transcontinental railroads and telegraph lines were built, each station was assigned its own two letter Morse code.
