San Francisco International Airport's IATA code?

• A. SFO
• B. SJC
• C. LAX
• D. LAS

Answer: (A)

IATA airport codes are three-letter identifiers used worldwide to name airports on tickets, baggage tags, and flight information. Each airport has a unique code that helps distinguish it from others, even when cities share similar names.

For San Francisco International Airport, the code is SFO. This three-letter tag is the standard label you’ll see on boarding passes, baggage tags, and flight boards for flights to and from San Francisco.

The other codes point to different airports: SJC belongs to San Jose International, LAX is Los Angeles International, and LAS is Las Vegas. Knowing these helps you quickly recognize which city each code represents. Therefore, San Francisco International Airport is identified by SFO.
