Montana State Government Telephone Directory
The State of Montana Government Telephone Directory lists Montana state office phone numbers by agency, by city or as toll-free listings, all in area code 406. The city view is handy for finding the state office in your own town rather than headquarters.
Find the office a caller named and call it back. General information is 406-444-2511 and the TTY line is 406-444-1421. For individuals, use the State Employee Search linked from the page.
Montana State Employee Directory
The Montana State Employee Directory finds a Montana state employee's phone number by first name or last name. You need at least two characters in one of the name fields, and you can narrow from All Agencies to a single agency.
If the caller's name is listed, reach them through their agency, not the number that called you. Support is at (406) 444-2000. Office numbers by agency or city are at directory.mt.gov.
Is Reverse Phone Lookup Legal in Montana?
Yes. Montana does not restrict the personal use of reverse phone lookup services. The state's privacy law has been in effect since October 1, 2024, giving residents rights to opt out of and delete their data from lookup databases. The Fair Credit Reporting Act (FCRA) prohibits using lookup results for employment, tenant, or credit decisions in every state. Montana's MT-CDPA provides additional state-level protections.
Your Privacy Rights as a Montana Resident
The Montana Consumer Data Privacy Act (MT-CDPA, Mont. Code Ann. § 30-14-3001 et seq., enacted SB 351, 2023) took effect October 1, 2024 and was amended in 2025. Note the correct abbreviation is MT-CDPA - both Montana's and Minnesota's laws were previously misabbreviated as "MCDPA" in some sources. Montana residents can opt out of personal data sales and targeted advertising, and have rights to access, correct, delete, and port their data within a 45-day response window. Nonprofits are generally exempt.

How to opt out of phone number lookup services in Montana?
Under the Montana Consumer Data Privacy Act (MCDPA), you can opt out of the sale of your personal details and request their deletion. Visit each reverse lookup site and use their opt-out form to submit a request.
How to tell if a Montana caller is a real business?
A phone number linked to a business name does not always mean the call is genuine. According to U.S. Census data, there are over 42,015 business establishments in Montana. To confirm a specific company exists, search the Montana Business Entity Search, the state’s official business entity registry.
Are Montana phone numbers harder to trace than other states?
Not inherently, but Montana's mix matters. The state has 1.2 million mobile subscriptions and only 152,000 VoIP lines, which means caller ID is more reliable here than in states with heavy VoIP adoption. Landlines still account for 104,000 subscriptions, a higher proportion than most states.
