Montana's 406 Area Code: Get a Local 406 Business Number
Montana is one of the few states that still has a single area code. Every Montana phone number starts with 406, from Missoula to Billings. Big Sky Telecom is a Montana provider, so a local 406 number for your business is what we do every day.
What Is Montana's Area Code?
Montana's area code is 406, and it covers the entire state. Montana has used 406 since area codes were created in 1947, so there is no separate area code for Missoula, Billings or any other city.
That makes Montana phone numbers easy to recognize. Customers see 406 on caller ID and know you are local.
