323 Area Code

On November 24, 2015, the North American Numbering Plan Administrator (NANPA) filed an application to introduce another area code, the existing 213, to the area now served by the 323. The CPUC opened a proceeding (A.15-11-017) to consider the NANPA’s application, and on July 14, 2016, the CPUC took action to ensure that phone numbers continue to be available to meet demand in the 323 area code by allowing both the 213 and 323 area codes to be used in the same geographic region.

Public Meetings were held on September 8, 9 and 10, 2015, in the City of Los Angeles, South Gate and South Pasadena. During the meetings, attendees asked questions and expressed their comments. Most were concerned about losing their existing phone numbers. CPUC and NANPA staff assured the audience that all customers will keep their existing phone numbers, including their area code. Only those requesting new or additional phone lines will be assigned the 213 area code.


The 323 area code is forecasted to use up all its available prefixes by the 3rd quarter of 2017.  Adding the 213 area code to the 323 will provide additional prefixes and ensure new telephone numbers are available for the 323 customers. The 323 area code, in addition to serving a large portion of the City of Los Angeles, serves the cities of Alhambra, Bell, Bell Gardens, Beverly Hills, Commerce, Cudahy, Glendale, Hawthorne, Huntington Park, Inglewood, Lynwood, Maywood, Montebello, Monterey Park, Pasadena, Rosemead, South Gate, South Pasadena, Vernon and West Hollywood. The 213 area code serves the downtown portion of the City of Los Angeles.
