About the official source
This is a statewide map, not a county site. MARIS Mississippi Statewide Parcels map viewer covers parcels across Mississippi, and Washington County is one part of it. A statewide layer can trail the county's own books by weeks or months, so treat it as a fast first look rather than the final word. When we tested the link in October 2026 it opened with no login and no fee.
Finding a property on this statewide map
- Press the button to load the statewide viewer, then move the map to Washington 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.
Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.

Before you rely on the lines
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.
