Area code 406 is Montana's only area code, covering the entire state — Billings, Missoula, Great Falls, Bozeman, Kalispell, and Helena. Billings is Montana's largest city and the primary commercial hub for the northern Great Plains, serving as a regional centre for energy, healthcare, and agribusiness across a vast geographic catchment. Malmstrom Air Force Base in Great Falls hosts one of the three Minuteman III missile wings in the US nuclear arsenal. Montana State University in Bozeman and the University of Montana in Missoula are growing research institutions, and Bozeman's tech ecosystem has attracted significant out-of-state migration, making it one of the fastest-growing small metros in the US. The state's outdoor recreation and tourism economy is a major economic pillar.
