History of the 415 area code
Area code 415 is one of the original 86 North American area codes established by AT&T and the Bell System in 1947. Originally it covered all of northern California from Monterey through the Oregon border. Successive splits carved off 916 (Sacramento, 1947), 707 (northern coast, 1959), 408 (San Jose, 1959), 510 (East Bay, 1991), and 650 (Peninsula, 1997), leaving 415 with roughly its current footprint: San Francisco proper, southern Marin County, and a sliver of northern San Mateo County. Overlay code 628 was activated in 2015 to handle number exhaust.
