Area code 818

About area code 818

Area code 818 is a geographic area code in California, in service since January 7, 1984, according to the North American Numbering Plan Administrator (NANPA). It is an overlay: 818 and 747 cover the same territory, so neighbors on the same street can have different area codes. It is in the Pacific time zone. The places with the most assigned exchanges include Burbank, Glendale, and Los Angeles. By population, its largest named places are Los Angeles, Glendale, and Burbank.

Ten-digit and seven-digit dialing in 818

According to NANPA's dialing-plan data, local calls within 818 are dialed as 1 plus ten digits and toll calls as 1 plus ten digits. Because local calls need the area code, business cards, signage and website copy should always show the full ten-digit number.

Who holds 818 exchanges

34 carriers hold the 781 central office codes assigned in 818. Pacific Bell has the most, with 265 (34%). 412 of the codes (53%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. The code holder is not necessarily the carrier serving a given number today, since numbers can be ported between providers.

Local calling areas in 818

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 818 has codes in 17 rate centers. Rate center names in the file are abbreviations; where one matches a Census place, the table links to that city's local-number page.
