Whether you're eyeing acreage outside Sumrall or settling a question about your own lot in Hattiesburg, the Lamar County parcel map is the first stop.
This guide walks through the official link, the kinds of land you'll find around Hattiesburg, and what to do when the map and the ground don't agree.
Opening the Lamar County parcel viewer
Start with the Lamar County parcel viewer; it opens in a normal browser with no sign-in. A parcel number from a Lamar County tax bill is the most precise search; failing that, an owner name or a click on the map near Hattiesburg works. Bookmark the Platbookmapper page for Lamar County too; we update it when the official map moves.
Reading property lines on the Lamar County parcel map
Lines on the map show roughly where one parcel near Purvis ends and the next begins; the exact spot is a surveyor's call. The section grid shapes many farm tracts around Arnold Line; boundaries often follow quarter-section lines you can spot on the map. For rural ground near Arnold Line, a recorded survey or a new one is the only reliable source for the true line.
What the map covers, from Purvis to the back roads
Parcel searches in Lamar County tend to center on Purvis, the county seat, plus Hattiesburg, Lumberton, and Sumrall. The county's land area is about 497 square miles, and the Census Bureau estimated 66,217 residents there in 2023. The mix of town lots in Sumrall and rural acreage beyond makes the Lamar County parcel map useful for house hunters and land buyers alike.
Private and public hunting ground in Lamar County
Near Sumrall, a single field edge can separate two owners with very different answers about access; the map tells you which is which. Before hunting around Sumrall, read the Mississippi Department of Wildlife, Fisheries, and Parks's current season rules. A landowner near Arnold Line is more likely to say yes to a hunter who names the exact parcel and offers a phone number.
Behind the map: land records in Lamar County
Recorded deeds and plats for Lamar County are kept by the chancery clerk, while the parcel layer is maintained for tax assessment. A deed or plat for land near Hattiesburg is kept by the Lamar County chancery clerk, Mississippi's land-records custodian. If you need a plat for a lot in Hattiesburg, look for the plat book and page or the subdivision name in the parcel record, then request that document from the recording office.
Who uses the Lamar County parcel map
Here's who tends to use it in Lamar County. Someone house hunting in Sumrall can check whether a yard really is as big as the listing implies, and who owns the open lot behind it. A builder sizing up an infill lot near Sumrall can check its width, depth and road frontage in a couple of minutes. Unlisted land near Purvis sometimes turns up this way: an empty parcel, an absentee owner, and a polite letter.
Before you rely on the data
A lot in Sumrall that sold last month may still show the previous owner on the map. Acreage on the Lamar County map is a tax figure; a survey is what a lender or buyer should rely on.
The Lamar County economy in brief

Measured against national shares, forestry and logging, pipeline transportation, and support activities for mining and drilling are overrepresented in Lamar County.
