Area code 424 is an overlay for the prestigious 310 area code in western Los Angeles County, including areas like Beverly Hills, Santa Monica, Malibu, and West LA. Introduced in 2006, 424 was implemented to address the growing demand for new phone numbers in this affluent and high-profile region. Residents and businesses in the 310/424 region are required to use ten-digit dialing. Although newer, 424 is becoming increasingly common, particularly for mobile and business lines. The region is synonymous with luxury, celebrity, and media, and both area codes are associated with prestige. 424 has been embraced as a part of modern LA culture while maintaining the legacy of the 310 area. It continues to serve one of the most economically dynamic and globally recognized parts of Southern California.
