History

Area code 415 was one of the original three area codes in California, established in 1947. It originally covered central California, south of area code 916 and north of area code 213.[1]

In 1950 there was a boundary realignment in which area code 916 was reduced to the north-eastern corner of the state and area code 415 was extended north to the Oregon border.[2]

For a short time in the early 1950s, area code 318 was temporarily used by customers in Englewood, NJ participating in the first customer direct distance dialing experiment to reach San Francisco as well as some areas north of the Golden Gate. [3]

On March 1, 1959, there was a 3-way geographical split of area code 415 which created two new area codes: 707 for the North Bay (excluding Marin County) and 408 for the South Bay.[4]

On September 2, 1991, area code 415 was split to create a new area code: 510 for Oakland and the East Bay.[5]

On August 2, 1997, area code 415 was split to create a new area code: 650. San Francisco, Marin County as well as portions of Brisbane and Daly City retained area code 415 while the remainder of the region to the south was assigned area code 650.[6]

Cultural Significance

In recent years, the number 415 has also taken on a local connotation of civic pride among the population of San Francisco. Though the City shares the area code with some of its suburbs, their common area code is becoming a cultural phenomenon; it is increasingly used in various capacities as a declaration of pride among San Francisco natives.
