Area codes 714 and 657, Telephone prefix in Orange County, California, US
Area codes 714 and 657 are telephone prefixes serving the northern portion of Orange County along with small sections of neighboring Los Angeles and San Bernardino Counties in Southern California. Both codes share the same geographic territory and operate as an overlay system.
California regulators created area code 714 in 1951 as one of the first regional separations from the original 213 prefix. Code 657 was added later as an overlay to meet growing demand for telephone numbers in this territory.
The 714 prefix appears on storefronts and business cards throughout this densely populated region, serving as a local identifier for residents and companies. Many longtime inhabitants regard their 714 number as a badge of connection to the area's growth and development.
All calls within these area codes require ten-digit dialing, including the prefix, even when caller and recipient live in the same neighborhood. This rule applies to both landline and mobile phones throughout the region.
Officials estimate that available number combinations for these prefixes will run out by March 2027. This shortage may lead to the introduction of another overlay code in the region.
