An IATA airport code, also known as an IATA location identifier, is a three-letter geocode used to identify airports and metropolitan areas worldwide. The International Air Transport Association (IATA) governs the assignment of these codes, which are published semi-annually in the IATA Airline Coding Directory. These codes are essential for the travel industry, playing a crucial role in identifying airlines, their destinations, and traffic documents. They are also used for passenger services such as tickets and baggage tags, with some airports adopting their IATA codes as brand names.

What You'll Learn
IATA codes are three-letter geocodes
An IATA airport code is a unique three-letter geocode that identifies airports and metropolitan areas worldwide. IATA stands for the International Air Transport Association, which governs the assignment of these codes. The codes are published twice a year in the IATA Airline Coding Directory and are used to identify locations, such as airports, bus or ferry stations involved in intermodal airline travel.
These three-letter codes are often derived from the names of the cities or airports they represent. For example, YUL is used for Montréal–Trudeau airport (UL was the ID code for the beacon in Kirkland, a city nearby). Some airports have even begun using their IATA codes as brand names, such as Calgary International Airport (YYC) and Vancouver International Airport (YVR).
The codes are also used for passenger services, such as tickets and baggage tags, and are essential for the smooth running of electronic applications built for passenger and cargo traffic. They are also used to identify an airline, its destinations, and its traffic documents.
While IATA codes are typically three letters, there are also two-letter codes in use. Some airports in the United States retained their National Weather Service (NWS) codes and simply appended an X to the end, such as PHX for Phoenix. In some cases, airports without scheduled passenger traffic may not have IATA codes but instead use other coding systems, such as the four-letter ICAO codes used by pilots.

They are assigned by IATA's headquarters in Montreal, Canada
An IATA airport code is a three-letter geocode used to identify airports and metropolitan areas worldwide. The International Air Transport Association (IATA) assigns these codes, which are governed by IATA Resolution 763 and administered by their headquarters in Montreal, Canada. The codes are published twice a year in the IATA Airline Coding Directory.
IATA codes are essential for the smooth operation of the travel industry, playing a critical role in identifying airlines, their destinations, and traffic documents. They are also used in various electronic applications built for passenger and cargo traffic management. The assignment of these codes is governed by specific guidelines, ensuring their effectiveness and efficiency in the travel industry.
The process of assigning IATA codes involves careful consideration and adherence to established standards. Airlines and Computer Reservation Systems (CRSs) can request unique three-letter codes to designate specific locations, such as airports. Bus or ferry stations that facilitate intermodal airline travel may also be eligible for IATA location identifiers.
The IATA headquarters in Montreal, Canada, plays a central role in managing and assigning these codes. The assignment process is systematic and governed by established procedures to ensure the accurate and consistent use of IATA codes globally. The semi-annual publication of the IATA Airline Coding Directory ensures that stakeholders in the travel industry have access to up-to-date information on airport and location codes.
While most IATA codes are three letters, there are also two-letter codes for airports. These two-letter codes were introduced in 1930, but they gradually transitioned to three-letter codes to accommodate the growing number of airports and locations. The older two-letter codes are still used in some cases, with an "X" appended to the end to differentiate them from the newer three-letter codes.

They are used for passenger services, like tickets
IATA airport codes are an integral part of the aviation industry and play a significant role in passenger services. These unique three-letter codes are assigned to airports worldwide by the International Air Transport Association (IATA) and serve as a simplified identifier for each airport. The codes are used extensively in passenger services, such as ticketing, baggage tagging, and flight scheduling, to provide convenience, efficiency, and accuracy.
When it comes to ticketing, IATA airport codes are essential. They are used to identify the departure and arrival airports on a ticket, ensuring that passengers and their luggage are routed to the correct destinations. The codes are typically displayed on the ticket in a concise format, such as "JFK-LHR," indicating a flight from John F. Kennedy International Airport (JFK) to London Heathrow Airport (LHR). This concise representation of airport names helps prevent confusion and errors, especially when dealing with airports that share similar names or have multiple names in different languages.
Baggage tagging also relies on IATA airport codes. When passengers check in their luggage, the bags are tagged with the IATA code of the destination airport. This helps ground handling staff and baggage sorting systems ensure that each piece of luggage is loaded onto the correct flight and transported to the right airport. Without these codes, identifying and sorting baggage for the thousands of flights operating daily worldwide would be incredibly challenging and prone to errors.
Additionally, IATA airport codes are used in flight scheduling and timetable publications. They provide a standardized reference for airlines and travel agencies when displaying flight options to passengers. By using these codes, passengers can easily identify the departure and arrival airports for their desired journeys. This is especially useful when booking connecting flights or navigating through large hub airports with multiple terminals. The codes help passengers quickly understand their routing and make informed travel decisions.

Airports and cities worldwide use them
An IATA airport code is a three-letter geocode used to identify airports and metropolitan areas worldwide. IATA stands for the International Air Transport Association, which governs the assignment of these codes. Airports and cities worldwide use them to simplify travel and location identification.
These codes are essential for the travel industry and are used for various purposes, including baggage tags, ticketing, and cargo documentation. They are also integrated into many electronic applications for passenger and cargo traffic management. For example, when checking in at an airport, the baggage tags attached to your luggage will display the IATA code of the airport, helping route your bags to the correct destination.
The codes are typically derived from the names of the cities or airports they represent. For instance, YYZ is the code for Toronto Pearson Airport, taken from the station code of Malton, Mississauga, where it is located. Some codes are derived from previous names of the airport, like Fresno Yosemite International Airport, which uses FAT, derived from Fresno Air Terminal.
In some cases, IATA codes are used as brand names for airports. Calgary International Airport (YYC) and Vancouver International Airport (YVR) are examples of this.
While IATA codes are predominantly three letters, there are some two-letter codes still in use, and four-letter codes are used for minor airfields without scheduled passenger traffic. These four-letter codes are known as ICAO codes and are used by pilots, while IATA codes are primarily used for passenger services.
Overall, IATA airport codes play a crucial role in streamlining travel operations and providing clear identification for airports and cities worldwide.
