To identify the location of an Montana phone number, you need to understand the North American Numbering Plan (NANP) structure that all Alabama numbers follow: +1 NPA NXX XXXX.
The area code (NPA) is your key to determining location. By matching the three-digit area code to Montana's regional assignments, you can identify which part of the state the phone number originates from. Each area code corresponds to specific cities and counties throughout Montana, making it possible to narrow down the caller's general location.
Here's a complete list of Montana area codes with major cities:
Area Codes | Cities |

Montana has approximately 1.46 million active phone numbers. Cell phones are the most popular type, with about 1.2 million users, while traditional landlines continue to decrease with about 104,000 connections statewide. Internet phone services have around 152,000 subscribers.
This means that when you search a Montana phone number, it's most likely a cell phone. The decreasing number of landlines implies newer phone numbers are often harder to trace compared to older landline numbers, which had more readily available public information.
