Why the San Fernando Valley Got a Second Area Code

Area code 747 is an overlay covering the San Fernando Valley, the large basin north of the Hollywood Hills that forms part of the city of Los Angeles, reaching Burbank's studio district, Van Nuys, North Hollywood, Woodland Hills, Tarzana, Northridge, Reseda, and the Ventura Boulevard corridor communities of Sherman Oaks, Encino, and Studio City. The valley was originally part of the 213 area code assigned when California's numbering plan launched in 1948; regulators split off 818 on January 7, 1984, to relieve pressure on 213, and in 1997 the San Gabriel Valley was further carved out as area code 626, leaving 818 with roughly today's San Fernando Valley footprint. By the mid-2000s 818 alone was again running short, so rather than splitting the territory a third time, the California Public Utilities Commission approved the 747 overlay on April 24, 2008, with numbers going into effect May 18, 2009 (some materials cite first assignments starting October 11, 2009); existing 818 customers kept their numbers while 747 applies only to new lines, and the shared territory now requires mandatory 10-digit dialing even between neighbors. The region sits in the Pacific Time Zone, observing PST and PDT. Reported scams against 747 numbers include government-impersonation calls, one-ring Wangiri callback schemes, fake studio and entertainment-industry scams offering bogus casting calls or production jobs to the valley's entertainment workforce, and neighbor spoofing matching a victim's own prefix; recipients should avoid sharing personal or financial data and report suspicious calls to the FTC. A business wanting a San Fernando Valley presence can provision a 747 number via a cloud platform like Softtop by searching California inventory and porting an existing number in five to ten business days.
