Area Codes -- Within the past 20 years, L.A. has gone from having a single (213) area code to a whopping seven -- with more promised by 2004. Even residents can't keep up. Here's the basic layout: Those areas west of La Cienega Boulevard, including Beverly Hills and the city's beach communities, use the 310 area code. Portions of Los Angeles county east and south of the city, including Long Beach, are in the 562 area. The San Fernando Valley has the 818 area code, while points east -- including parts of Burbank, Glendale, and Pasadena -- use the newly created 626 code. What happened to 213, you ask? The downtown business area still uses 213. All other numbers, including Griffith Park, Hollywood, and parts of West Hollywood (east of La Cienega Blvd.) now use the new area code 323.
