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 as area code 775. Nevada's explosive growth in the second half of the 20th century, and the corresponding expansion of telephone service, would have made a second area code a must in any case. However, the split was hastened by the proliferation of cell phones and pagers, particularly in Las Vegas, Reno, and Carson City. The split followed rumors that the area code 777, which are the winning number combination for slot machines, was considered for the state. However, the triple-seven area code was reserved for the same reasons as was the similarly-recognizable 555 area code.[1] 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, for which "1" must be dialed first.[2] Under current projections, the Las Vegas area will not need another area code until late 2045 at the earliest.[3] Despite Las Vegas' continued growth, 702/725 is nowhere near exhaustion.
