Area code 424

Area code 424 serves California, including Beverly Hills, Inglewood and Redondo (Pacific time). It has been in service since August 26, 2006 and shares its area with 310.

Numbers starting with 424 drew 1,385 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 711 complaints to the FCC since November 2023. The number on your screen can be faked, so a 424 number proves nothing about where a call came from.

Phone companies holding 424 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 100% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
