About the official source

This is a statewide map, not a county site. OKMaps (Oklahoma Office of Geographic Information) - Statewide Parcels layer covers parcels across Oklahoma, and Grant 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

  1. Open the statewide viewer in a new tab and move the map to Grant County (around Medford).
  2. Nothing parcel-related shows at first. Add it through Explore > Land Parcels > Statewide Parcels, then click the green +.
  3. Zoom in closely; at wide views the parcel layer stays blank.
  4. Click a parcel to see its record, and keep the parcel ID handy for later searches with the county assessor or county clerk.

Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.

A note on accuracy

Online parcel lines are drawn for tax and planning use. They can be off by several feet, so use a recorded plat or a licensed surveyor for fences, setbacks or a sale.
