Where the parcel data comes from
This is a statewide map, not a county site. Montana Cadastral (Montana State Library) covers parcels across Montana, and Phillips County is one part of it. Statewide parcel layers are usually stitched together from county files, so the newest splits or sales may show up on the county's own records first. As of our October 2026 test, anyone could open it without signing in or paying.
Finding a property on this statewide map
- Open Montana Cadastral (Montana State Library) in a new tab and zoom to Phillips County (around Malta).
- Type a street address into the search box, or click directly on a parcel.
- Review the parcel attributes; field names vary by state.
- Confirm anything important with the county assessor, since the statewide layer is a compiled copy.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.
