History

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 its boundaries were realigned: area 916 was reduced to the north-eastern corner of the state and 415 was extended along the north coast to the Oregon border.[2]

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

Area 415 has been split three times:
