History
In 1959 numbering plan area 415 was divided in a flash-cut (without permissive dialing period) in which the northern part of the numbering plan area (Solano County and north thereof) received area code 707, which was California's eighth area code (along with 213, 415, 916, 714, 408, 805, and 209), and the last new area code in the state until 619 was added in 1982.
