History of Area Code 818
Area code 818 began service on January 7, 1984, after a split from area code 213. The new code served the San Fernando Valley and nearby communities as Southern California needed more telephone numbers.
Area code 626 was created from part of the 818 region in 1997 to serve the San Gabriel Valley. In 2009, area code 747 began overlaying 818, which allowed both codes to serve the same geographic area. The overlay also made ten-digit dialing necessary for local calls.
