History of Area Code 707
Area code 707 was established in 1959 by splitting northern California territory from area code 415. The new code served the North Coast and North Bay as residential and business telephone use expanded beyond the original 415 numbering area.
Area code 707 later received an overlay rather than another geographic split. Area code 369 entered service on March 1, 2022, adding new number combinations while allowing existing 707 customers to keep their numbers.
