Are IATA codes always three letters long?

• A. Yes
• B. No
• C. Sometimes
• D. Depends on the airport

Answer: (A)

IATA codes are standardized and are indeed always three letters long. The International Air Transport Association (IATA) established this coding system to create unique identifiers for airports around the globe. Each airport is assigned a three-letter mnemonic that is typically derived from the airport's name or location, making it easier for passengers and airline personnel to remember. This three-letter structure ensures consistency across the airline industry, facilitating ticketing, baggage handling, and flight operations. While some users may mistakenly believe that codes could vary in length, the IATA code system is strictly defined to be uniform with this three-letter requirement.
