How the Montana Registry Works
The Montana Department of Justice runs Montana's registry. Before you search, know what the public site includes and what it legally can't show — the answer differs state to state, and Montana's version has its own rules.

NSOPW — National Search (includes Montana)

The US DOJ's national portal queries every state, territory, and tribal registry at once — the only true cross-state search. Start here when the person may have moved.
VINELink — Custody Status
Official Free
If a registrant is currently in custody, VINE tracks it and alerts you on release — the registry itself only shows the registered address.
Frequently Asked Questions
Does the Montana website show every registrant?
Montana's combined Sexual or Violent Offender Registry covers both categories in one search — check the offense type before assuming. The national NSOPW search fills cross-state gaps.
Can I get alerts for my address?
Most state registries offer email alerts for a radius around addresses you save — school, home, workplace. Set them once and the registry watches for you.
What can I legally do with registry information?
Awareness and protection. Every state criminalizes using the registry to harass, threaten, or discriminate against a registrant — landlords and employers have separate rules to follow.
Someone on the registry lists a wrong address. Who do I tell?
The sheriff verifying that area, or the Montana Department of Justice directly — address verification is the compliance backbone, and tips get acted on.

The registry shows registration, not the case: Montana court records hold the underlying conviction, the criminal records page covers full background checks, and the inmate search shows who is in custody now.
