Area Code 818


The 818 Area code was initially created in 1984. In 1947, after the standardization of American telephone area codes, Los Angeles County was using the 213 area code. With the passage of time the population increased, their needs of communication also enhanced, resulting in more phone usage in Los Angeles during the 1980s and 1990s.

So that, the area code 213 splits into several new area codes, including the 818. The area code 818 was officially activated and served in specified areas on 7 January 1984.

Area code 818 was further split in to area code 626 on June 14, 1997 for the San Gabriel Valley of Southern California, situated to the east of the city of Los Angeles.

Later, In November 1999, the proposal happened for a new 747 area code would split from 818 to serve the southern and western portions of the San Fernando Valley. California Public Utilities Commission (CPUC) decided to implement 818/747 split, or an overlay of 818 with 747. Public accepted to implement an overlay of 818/747 rather than split

So, CPUC decided that 747 area code would overlay area code 818 on April 24, 2008. It would be functional on May 18, 2009. For some period of time callers of 818/747 area code could make calls by using old seven digit number. Due to overlay of 747 area code the dialing procedure was changed.

New Dialing Procedures of 818 area code

There was a need to inform people under the area code of 818 with the new dialing method. On April 10, 2009. The California Public Utilities Commission (CPUC) reminded consumers in the area code 818 that due to the 747 area code overlay.
