Airport Codes by State 2023

Airport codes are defined by the International Air Transport Association (IATA). An IATA airport code, also known as an IATA location identifier, IATA station code, or simply a location identifier, a three-letter geocode designating many airports around the world.

Because there are often multiple airports near major cities, the air transportation industry needed to find a method of referring unambiguously to specific airports. This is where airport codes come into play as location identifiers.

How Are Airport Codes Assigned?

IATA Resolution 763 governs the assignment of these codes. Resolution 763 states that all member airlines must use the location IDs published three times per year in the “Airline Coding Directory.” The codes are used for ticketing, reservations, and baggage handling, among other uses. Most commonly, the airport code can be seen on the baggage tag added to checked bags at the check-in counter.

Location IDs covering United States airports are assigned by IATA in conjunction with the Air Transport Association (ATA). Some of the main features of the IATA/ATA location IDs are:

• All codes are in combinations of three letters.
• When possible, IATA assigns codes that coincide with the first three letters of the airport’s location or at least with the first letter of the name.
• Sometimes codes correspond with less obvious historical associations for a location (such as MCO for Orlando).
• In some cases, the first letter of an airport’s name is omitted and subsequent letters are used (such as wILMington).
• IATA codes are typically the same as the FAA-assigned three-letter codes. (but not always)
• Codes are considered permanent and are rarely reused.
