Historical Background of 415 Area Code
Pacific Bell introduced the 415 area code during the first wave of North American area code implementations. The code initially covered a vast territory stretching from the Oregon border to the central California coast. As population growth intensified telecommunications demand, the 415 region underwent two major splits: the 707 area code separation in 1959 for the North Bay region and the 510 code creation in 1991 for the East Bay. AT&T’s records indicate the code reached 98% capacity by 1997, leading to the establishment of overlay code 628 in 2015.
