Geographic Coverage & Key Cities

The 657 area code serves northern Orange County and parts of Los Angeles and San Bernardino Counties, covering 19 cities including Anaheim, Santa Ana, Irvine, Huntington Beach, and Fullerton. It was introduced on September 23, 2008, as an overlay to the existing 714 area code to accommodate the rising demand for new phone numbers due to rapid population growth and the widespread use of mobile devices. This setup allowed existing 714 numbers to remain unchanged while making room for new ones without disrupting service.

The history of the 714 area code stretches back to 1951, when it was split from the original 213 code, one of the first area codes established in the United States in 1947 under AT&T's nationwide numbering plan. At one point, 714 covered a large portion of Southern California, including most of Orange County.

As the region developed and the population surged, 714's coverage area was gradually reduced. Notably, in 1998, area code 949 was created to serve the southern portion of the county. The introduction of 657 as an overlay was a modern solution to avoid additional geographic splits and maintain consistency.

Today, Orange County stands as a leading economic hub in California, boasting a diverse mix of industries that include technology, tourism, real estate, healthcare, and entertainment. Attractions like Disneyland, alongside a growing number of startups and established firms, drive business activity across the region. The dual presence of area codes 657 and 714 reflects both the area's growth and its deep-rooted role in California’s telecommunications and economic landscape.

Time Zone & Business Impact

The 657 area code operates within the Pacific Time Zone, placing your business 8 hours behind Coordinated Universal Time (UTC-8) during standard time and 7 hours behind during Daylight Saving Time. DST runs from March to November, requiring operational adjustments twice a year. Operating in Pacific Time offers distinct advantages, particularly for businesses in technology or entertainment, as you're synchronized with other West Coast innovation centers and Hollywood production schedules.

When your 657-based business opens at 9:00 AM, East Coast clients are already at lunch, making early morning an ideal window to connect with local customers. For companies operating across multiple time zones, careful management is essential during both standard time (PST) and daylight saving time (PDT). Services like Goodcall's AI answering service automatically adjust to time changes without interruption, ensuring continuous availability.
