323/213 Area Code

On July 14, 2016, the California Public Utilities Commission (CPUC) approved a boundary-elimination overlay in Decision 16-07-014 to accommodate the need for additional telephone numbers in the 323 area code region. On August 1, 2017, the overlay became effective and the existing 213 area code was overlaid onto the 323 area code.

The overlay allows existing 323 area code customers to keep their telephone numbers and the 323 area code. However, calls made from the 323 or 213 area code need to be dialed as 1 + area code + 7-digit telephone number. Calls placed from 323 or 213 numbers without the “1” and the area code will not be completed and will result in a recording instructing the caller to hang up and dial again. Cellphone callers who have service with certain cell service providers may be able complete calls without dialing “1” before the area code.

Dialing 1 + area code + 7-digit telephone number does not change what a call costs and does not mean that a call is a toll or long distance call. Therefore, calling areas and rates do not change. What is a local call before the overlay remains a local call after the overlay and dialing “1” and the area code does not mean there is a charge for the call. Calls to 911, as well as 211, 311, 411, 511, 611, 711 and 811 are not affected, and continue to be dialed with 3 digits.


The 323 area code was created when it was split off of the 213 area code in June 1998. 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. The 213 area code, created in 1947 as one of the original three area codes in the state, today serves the downtown portion of the City of Los Angeles within the county of Los Angeles.

The 323 area code is bordered on the north by the 818/747 area code overlay complex, to the west by the 310/424 area code overlay complex, to the east by the 626 area code and to southeast by the 562 area code.
