What city does the code SFO correspond to?

The code SFO corresponds to San Francisco, California, which is consistent with the IATA airport code system used internationally to identify airports. Each airport has a unique three-letter code, and SFO is specifically designated for San Francisco International Airport. This code provides a standardized way to refer to the airport in schedules, bookings, and travel itineraries, making it easier for travelers and airlines to communicate about destinations without confusion. The other options correspond to different cities but do not share the SFO designation, reinforcing the specificity of the city code system.
