NPA 775 split from 702 for northern Nevada

Area code 775 was created on December 12, 1998, when it was split from area code 702. The split divided Nevada geographically, with 775 assigned to the northern and rural parts of the state, including Reno and Carson City, while 702 continued to serve Clark County and Las Vegas. This split reduced area code 702 to serve only Las Vegas and the surrounding area.
