Montana, known for its vast landscapes and rural character, is served by two primary area codes: 406 and the recently added 557. Established in 1947, the 406 area code covers the entire state, reflecting Montana's relatively low population density—approximately 1.1 million residents as of the 2020 census. This expansive coverage spans urban centers like Billings and Missoula, as well as remote areas and small towns, emphasizing the sparse nature of its population distribution.
In response to growing demand for phone numbers, particularly due to the increase in cellular and data services, the 557 area code was introduced in 2021 as an overlay for the existing 406 region. This allows for a greater supply of telephone numbers while maintaining the integrity of the existing 406 code.
Montana's unique geography can influence telecommunications. The state's mountainous terrain often leads to variations in signal strength and coverage, posing challenges for traditional phone services. Consequently, many rural areas rely heavily on mobile and satellite communications, which further shapes the telecommunications landscape.
Understanding Montana's area codes is essential not just for making calls but also for grasping the broader context of communication infrastructure within a region characterized by its demographic and geographic singularities. The area codes play a critical role in connecting communities across the state.

Montana has 1 area codes (406). These area codes are split between cities or states, so if you want to call to Montana, you need to know exactly where you would like to call.
The first 3 digits to call Montana may vary depending on where you want to call to, being one or the other depending on the region or city. Take a look at our listing above to find out which area code you need.
Calling Montana from another state in the United States is considered a long-distance call. Here’s how to make the call: First, dial the area code for Montana. Each state, and sometimes specific cities within a state, has unique area codes. Then, enter the 7-digit phone number of the person or business you’re trying to reach. If you’re calling from a landline, check with your provider, as long-distance charges may apply. However, most mobile carriers in the U.S. offer nationwide calling without additional fees. Alternatively, you can use VoIP or internet-based calling apps, like Skype, Zoom, or WhatsApp, to bypass traditional long-distance charges. The number you want to reach should look like this: 1-(AreaCode)-111-2222.
When making calls within the United States, dialing +1 depends on several factors. On most modern mobile phones, carriers automatically recognize the country code when calling within the U.S., so dialing +1 is usually not required; you can simply enter the area code followed by the phone number, such as 213-555-1234. If you’re using a landline, dialing 1 (the U.S. country code) before the area code and phone number is often necessary for long-distance calls; for example, calling from one state to another may require dialing 1-213-555-1234. When calling the U.S. from another country, dialing +1 is necessary, so a call from abroad would be formatted as +1-213-555-1234. VoIP and internet-based calling platforms, like Skype and WhatsApp, generally handle country codes automatically, making it unnecessary to dial +1 manually for U.S. numbers.
