what area code is 308

The area code 308 is located in western Nebraska and covers cities such as Grand Island, Kearney, and North Platte. It was created on July 1, 1954, by splitting the numbering plan area (NPA) 402 along a roughly S-shaped boundary from the Wyoming border to the Kansas border. The 308 area code covers both the Mountain and Central time zones. According to projections, the 308 area code will remain in its current configuration until at least 2050, as its supply of telephone numbers is in no immediate danger of exhaustion.
