Understanding Montana’s Only Area Code: 406

Understanding Montana’s 406 Phone Number Area Code

The 406 area code in Montana is one of the most iconic and long-standing telephone codes in the United States. Established in 1947, it has served the entire state of Montana ever since. Unlike most U.S. states

that now have multiple area codes, Montana proudly operates with just one — 406.

If you’re a business owner, marketer, or resident interested in buying a Montana local phone number or learning about its telecommunications history, this article covers everything — from city listings

and dialing rules to how to get a Montana virtual number for your company.

What Is the Montana Area Code?

Area code 406 represents the entire state of Montana, covering cities, towns, and rural regions alike. Assigned in October 1947 as part of the North American Numbering Plan (NANP), it remains one of the few single-area-code states

in the country.

According to Wikipedia’s entry on area code 406, the number has become a cultural symbol for Montana — often seen on local apparel, business branding, and state-themed merchandise.

The Story Behind Montana’s Area Code 406

When the North American Numbering Plan was introduced by AT&T in 1947, Montana was assigned 406. With its vast land area but relatively small population, there was no immediate need for additional codes. Even decades later, Montana’s

population density remains one of the lowest in the nation, allowing the 406 code to persist statewide.

From rotary phones to cloud-based

business phone systems, Montana’s 406 area code has stayed constant.

Montana’s 10-Digit Dialing Update
