406 area code summary

Area code 406 covers the entire state of Montana, making it one of the few states in the U.S. with a single area code. Established in 1947, it’s a badge of statewide identity, spanning all major cities including Billings, Missoula, Bozeman, Great Falls, and Helena. The economy of Montana is rooted in agriculture, mining, tourism, and increasingly, tech and education. Missoula and Bozeman have grown into regional tech and university hubs, hosting the University of Montana and Montana State University, respectively. Outdoor recreation—from skiing to fishing—plays a central role in local culture and business. Tourism to Yellowstone and Glacier National Parks also brings substantial seasonal business activity. A 406 number instantly communicates authenticity and local presence across a rugged, independent state. Whether you’re a real estate agent in Bozeman, a contractor in Billings, or launching an online business in Kalispell, 406 carries weight and trust in Montana.

Fun fact 💡
