California – New 213/323/738 area code overlay

To ensure a continuing supply of telephone numbers, the California Public Utilities Commission has approved an additional all-services overlay for the 213/323 area code overlay region. The 213/323 area code overlay region serves downtown Los Angeles, 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, West Hollywood, and unincorporated portions of Los Angeles County. The new 738 area code will serve the same geographic area currently served by the 213 and 323 area codes.

Beginning November 1, 2024, customers in the 213/323 area code region may be assigned a number in the new 738 area code when they request new service or an additional line. Customers receiving the 738 area code will be required to dial 1+ the area code and phone number for all local calls, just as customers with telephone numbers from the 213/323 area code overlay region do today.
