History
After the introduction of American telephone area codes in 1947, almost all of Los Angeles County used area code 213. During the 1980s and 1990s, the population and the demand for telecommunication services grew substantially in the Los Angeles metropolitan area, so that area code 213 came under resource pressure. In relief the numbering plan area was divided with several new area codes, including area code 818 and area code 310. Area code 818 entered service on January 7, 1984, making Los Angeles one of the first major cities to be split into multiple numbering plan areas.

was assigned to a portion of the eastern part on June 14, 1997.
In November 1999, telephone administrations proposed an additional area code "at some future date". NPA 747 would be would split from 818, for the southern and western portions of the San Fernando Valley. This proposal sat dormant until 2007, when the telephone industry and the California Public Utilities Commission commenced resource utilization studies for relief action. Public sentiment indicated a preference for overlay action rather than a split, since 818 customers would retain the area code. Only new service would require the new area code.
On April 24, 2008, the CPUC decided that area code 747 would overlay area code 818 effective May 18, 2009. From that date, new numbers could be assigned to the new area code. All calls within the numbering plan area now required
