The rules in Montana

Montana sex offender laws & risk levels

Three risk levels. Montana courts designate sexual offenders as Level 1 (low), Level 2 (moderate), or Level 3 (high risk). All levels appear on the public registry, with the level flagged on each record; Level 3 offenders face the broadest notification.

No statewide residency restriction. Montana law does not restrict where registrants live; individualized conditions apply through supervision.

Registration & verification. Registrants must keep their address, employment, and schooling current with the registry, and verify in person on a recurring schedule — more frequently for higher-risk or higher-tier registrants. Failure to register or verify is itself a crime and commonly appears as a listed offense on registry records.

Common questions

Montana sex offender registry FAQ

How many registered sex offenders live in Montana?

As of July 2026, there are 5,037 registered sex offenders in Montana — about 46.5 for every 10,000 residents, 94% above the national average. Counts change as offenders register, move, or are removed from the registry.

Which city in Montana has the most sex offenders?

Billings has the most registered sex offenders in Montana with 946. Raw counts track population, so the fairer comparison is per capita: adjusted for population, Helena has the highest rate among major cities at 111.2 per 10,000 residents, while Bozeman has the lowest at 17.7.

How do I find sex offenders near my address in Montana?

Use the free Predator Map app to search any Montana address and see registered offenders around it on a map, with photos and offense details from official registry records. You can also search the official Montana Sexual or Violent Offender Registry (DOJ) website directly.

Why is this number different from the official Montana registry website?

Public registry websites only show what the state chooses to publish. Montana publishes all levels, but its registry mixes sexual and violent offenders — this page counts sex offender records only. Statistics on this page are compiled from aggregated official registry records, so they can differ from — and often exceed — what a manual search of the public site returns.

Does Montana restrict where sex offenders can live?

No statewide residency restriction. Montana law does not restrict where registrants live; individualized conditions apply through supervision. Address-level monitoring matters more than assumptions about "safe" neighborhoods.

What do Montana's levels mean?

Montana courts assign Level 1 (low risk of repeat offense), Level 2 (moderate), and Level 3 (high). All levels appear on the public registry with the designation shown. There are currently 286 registrants at the highest classification in Montana.

How current is this data?

Statistics on this page are compiled from official state registry records and refreshed monthly. This page was last updated in July 2026. Always verify individual records with the official state registry.

Can I get alerts when a sex offender moves near me in Montana?

Yes. Predator Map Pro monitors up to 5 addresses daily and sends push and email alerts when a registered offender moves in nearby, a new offender registers, or someone moves away.

Is it legal to look up sex offenders near me?

Yes. Registry information is public record under federal and state law (Megan's Law), and anyone may search it to protect themselves and their family. What the law prohibits is using registry information to harass, threaten, or commit a crime against a registrant — misuse can be prosecuted.

Methodology: Statistics are compiled from aggregated official state registry records and refreshed monthly. City figures count the city listed on each registry record. Per-capita rates use 2020 U.S. Census populations. Aggregated counts can exceed what public registry websites display because some classification levels are excluded from public searches. Figures are estimates and change daily as registries update — always verify individual records with the official state registry.
