Where the parcel data comes from

It is a county-level map: Natrona County or the company it hires keeps the parcel layer up to date. When we tested the link in October 2026 it opened with no login and no fee.

Searching for a parcel, step by step

  1. Press the button above; an ArcGIS Experience Builder app opens in a new tab. Accept any splash or disclaimer screen.
  2. Search by address or parcel ID, or pan to the area.
  3. Select a parcel to view the information the publisher makes available.
  4. Explore the app's panels for layers, legends or printing.

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.
