Feature Answer

What is Area Code 310?

Area code 310 is a North American telephone area code assigned to LA Westside, covering Beverly Hills, Santa Monica, Westwood. It was created in 1991 when area code 213 was split to handle growing demand. The code is local rather than toll-free, and it operates on Pacific Time.

Before 1991, LA Westside was part of the larger 213 footprint. As the region grew, the FCC carved out 310 to serve its own community, leaving 213 to anchor a more focused area. Today 310 is the recognized code for LA Westside, used across local businesses, institutions, and households.
