Area codes 818 and 747

Area codes 818 and 747 are telephone area codes in the North American Numbering Plan (NANP) for the San Fernando Valley region of Los Angeles County in the U.S. state of California.

Area code 818 was created in a split from area code 213 on January 7, 1984. On June 14, 1997, 818 was reduced in size to create a separate numbering plan area (NPA) for most of the San Gabriel Valley with area code 626. On May 18, 2009, area code 818 was overlaid with area code 747.

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 among multiple area codes. Area code 626 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 ten-digit dialing. A permissive dialing period started October 11, 2008 during which seven-digit dialing was still possible. As of mid-April 2009, calls must be dialed with the area code and number.

The first telephone number block was assigned to area code 747 on October 11, 2009.
