Montana State in United States

Montana, known as Big Sky Country, is celebrated for its wide-open spaces, stunning mountain ranges, and national parks like Glacier and parts of Yellowstone. With a strong frontier spirit and a deep connection to the outdoors, Montana remains one of the most naturally preserved and sparsely populated states in the U.S.

Montana is served entirely by a single area code — 406, which has been in place since 1947. Despite modest population growth, area code 406 continues to support the entire state, from Billings and Missoula to remote ranching towns and scenic wilderness areas. It stands as a symbol of Montana’s unified, low-density communication network.
