Area codes 702 and 725

Area codes 702 and 725 are the North American Numbering Plan telephone area codes serving Clark County, Nevada, including Las Vegas. Area code 702 was originally assigned to the entire state of Nevada, as one of the original numbering plan areas established in October 1947. On December 12, 1998, most of Nevada, including Reno and Carson City, was split off with area code 775 to accommodate the explosive growth of telephone service in the area due to the proliferation of cell phones and pagers, particularly in Las Vegas, Reno, and Carson City.

Since May 3, 2014, area code 702 has been overlaid with area code 725. Ten-digit dialing is required for all calls, with exceptions for landline-based callers calling long distance within the county and prefix 976, for which "1" must be dialed first.

Despite Las Vegas' rapid growth, the plan area is not threatened by exhaustion; Las Vegas is projected to not need another area code until 2042.
