The 310 area code serves Los Angeles (Westside), Beverly Hills, Santa Monica and Malibu in California, on Pacific Time. Here's the full rundown — and how Aria answers every 310 call for your business, day and night.
The 310 area code covers the Westside of Los Angeles County in California, serving communities such as Beverly Hills, Santa Monica, Malibu, and the South Bay. It is one of the most recognized area codes in the United States, associated with the affluent coastal and entertainment districts of greater Los Angeles. Because demand for local numbers has grown steadily, 310 is overlaid by the 424 area code, meaning both codes serve the same geographic footprint and ten-digit dialing is required for all local calls.
Businesses operating in the 310 area code run on Pacific Time, which is UTC minus eight hours in winter and UTC minus seven during daylight saving. That places them three hours behind the East Coast, meaning a New York client calling at 9 a.m. reaches a Los Angeles office at 6 a.m. — well before most staff arrive. After-hours calls are a constant reality for Westside businesses. Missing those calls means losing leads to competitors who pick up. An always-on answering solution ensures every inquiry is captured regardless of the hour.
