Area code 415 is one of the original area codes established in North America in 1947, serving the central region of California. Its creation coincided with the advent of the North American Numbering Plan, designed to simplify telephone networks across the continent. Initially, area code 415 covered a vast area, including San Francisco, Marin County, and parts of San Mateo County.

Over the years, the region's population growth and increased demand for phone lines led to the splitting of area code 415. In 1991, the surrounding areas transitioned to area code 510, and in 1997, further reassignments established area code 628 as an overlay for the same geographical region. Despite these changes, area code 415 remains synonymous with San Francisco, representing both the city and its cultural identity.
