(424) Area Code Business Phone Numbers
The 424 area code covers the Westside of Los Angeles, the Beach Cities, and the South Bay, with Torrance as its anchor. Introduced in 2006 as California's very first overlay code[1], it now lives side by side with 310 across the same neighborhoods.

The 424 code went live on July 26, 2006 as an overlay on top of 310, which was running out of numbers after years of Westside growth[1]. Because two codes share the same footprint, every local call in the region uses ten-digit dialing. In practice, that means a 424 number sits comfortably next to a 310 number in the same neighborhood without confusing anyone.
Torrance itself leans on manufacturing, healthcare, and professional and technical services as its three biggest employers[2]. You have Honda's former North American HQ legacy, Toyota's long history in the city, medical offices along Hawthorne Boulevard, and small aerospace suppliers tucked into industrial parks off Del Amo. It is a working city, and phones still ring during business hours.
If you are selling to South Bay locals or Westside offices, a 424 number reads as one of them. People in Manhattan Beach or Culver City recognize the code, and they answer more often than they answer an out-of-state area code. That is the whole point of picking up a local number instead of a random toll-free line.
