Montana's single 406 area code covers the entire Big Sky State — from Billings' energy and agriculture economy to Bozeman's booming tech and tourism sector.
Montana uses a single area code, 406, spanning the entire Big Sky State — Billings (the largest city), Missoula (University of Montana), Great Falls, Bozeman (Montana State), Helena (the capital), Kalispell, Havre, and the vast rural stretches of the Rocky Mountain west — in the Mountain Time zone.
Montana's single 406 area code covers the entire Big Sky State — from Billings' energy and agriculture economy to Bozeman's booming tech and tourism sector. Montana's 406 code covers Big Sky Country's emerging remote-work economy — Bozeman is one of the fastest-growing small cities in the US — alongside Billings' energy and agricultural distribution hub, Missoula's University of Montana research cluster, and Glacier National Park's multi-billion-dollar tourism economy.
