657 Area Code in California, United States

Area code 657 is an overlay of 714, serving northern Orange County including cities like Anaheim, Santa Ana, Orange, Fullerton, and Huntington Beach. Introduced in 2008, 657 was created to alleviate number shortages in the already densely populated 714 region. This area includes major attractions such as Disneyland Resort, making the 657/714 region a hub for tourism and business. The overlay means residents and businesses in the area could have either a 657 or 714 number, with ten-digit dialing required. Despite being newer, 657 is increasingly seen as part of the Orange County identity, especially as mobile and business lines adopt it. The area is known for its suburban lifestyle, beaches, and growing tech and healthcare industries, making 657 a key identifier in one of Southern California’s most dynamic regions.
