History of Area Code 657
Area code 657 entered service on September 23, 2008, as an overlay for area code 714. The overlay was added because the 714 area had a growing need for new telephone numbers. An overlay allows a new area code to serve the same geographic area without changing existing telephone numbers.
Area code 714 dates to 1951, when it was created through a split from area code 213. Later splits from the 714 region created area code 619 in 1982, area code 909 in 1992, and area code 949 in 1998. The 657 overlay preserved existing 714 numbers and made ten-digit dialing necessary for local calls.
