Area codes 702 and 725 are telephone area codes in the North American Numbering Plan (NANP) for Clark County, including Las Vegas, in the U.S. state of Nevada. Area code 702 was one of the original North American area codes established in October 1947, and serviced the entire state of Nevada until 1998, when it was reduced to Las Vegas and the surrounding area. In 2014, area code 725 was added as an overlay plan covering the same area.
