The area code 657 is located in Anaheim, California.
Area code 657 serves Anaheim and much of northern and western Orange County, California, as an overlay to the long-standing 714 area code. Introduced in 2008, this overlay supports one of the busiest hubs in Southern California, home to major attractions and business centers. In Anaheim, 657 reaches world-famous landmarks like the Disneyland Resort, Angel Stadium, and Honda Center, making it a key area code for tourism, entertainment, and local commerce.
Area code 657 covers many communities in the 714 region, including:
Because 657 is an overlay, existing 714 numbers stayed the same, and new numbers may be assigned 657. The region uses 10-digit dialing for all local calls, but calling areas and rates didn’t change with the overlay. If you see a 657 phone number, it’s a local Orange County number that shares the same footprint as 714.
The 657/714 pairing reflects Orange County’s steady growth after decades of change to its numbering plan, including the creation of 949 for south county in the late 1990s. Landmarks like Knott’s Berry Farm in Buena Park and the Huntington Beach Pier also sit within the 657/714 territory, highlighting the area’s mix of tourism, surf culture, and suburban neighborhoods. The area code follows Pacific Time (PT), including daylight saving time, aligning with the broader Los Angeles metro.
