About the official source
Carbon County doesn't have its own viewer in our directory, so we point you to a statewide map: Montana Cadastral (Montana State Library). Zoom in on Carbon County to see its parcels. 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.
How to use the Carbon County viewer
- Press the button to load the statewide viewer, then move the map to Carbon County.
- Use the viewer's search tool to find an address or parcel, if it has one.
- Click a lot to read its details.
- For deeds, taxes or official copies, take the parcel number to the county's own offices.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.

Maps vs. surveys
Keep in mind that a GIS parcel layer is a tax map, not a survey. For exact boundaries, look at the recorded deed and plat or hire a licensed land surveyor.
