More About Area Code 415

Area code 415 is one of the original 86 area codes created by AT&T and the Bell System in 1947. It originally served northern/central California including San Francisco and Sacramento. In 1997, area code 415 was split, and some of the phone numbers had to be updated to area code 650 on that date. In 2015, area code 628 was created as an overlay to area code 415. Currently, the largest city it serves is San Francisco, CA, and it overlaps coverage areas with area code 628.
