New and additional phone lines in the West Hollywood area will be assigned the 738 area code starting November 1.
The nascent area code will join 323 and 213 in representing 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 and unincorporated portions of Los Angeles County, according to Spectrum.
Those who already have 323 and 213 numbers won’t be affected, nor will pricing, availability or coverage.
The 213 area code was created in 1947 and was one of the original three area codes in California.
The 213 area code was split five times between 1951 and 1991, creating the 714 area code in 1951, the 805 area code in 1957, the 818 area code in 1984, the 310 area code in 1991 and the 323 area code in 1998. In 2017, the CPUC approved an elimination of the boundary between the 213 and 323 area codes, creating the 213/323 overlay area codes.
