History of Area Code 657

Area code 657 was established on September 23, 2008. The California Public Utilities Commission approved it as an overlay for area code 714, which means both area codes serve the same geographic area.

Area code 714 is one of California's older area codes, and number demand in Orange County led to the new overlay. The overlay system allowed the region to add new phone numbers without changing existing 714 numbers. After the overlay began, 10-digit dialing became necessary for local calls in the 714 and 657 area.
