DeSoto County (Southaven and Olive Branch; pop. 185,000; Memphis metro south) is Mississippi's fastest-growing county and carries the highest parcel-lookup demand in the state. The Tax Parcels layer sits at index 28 of the DeSoto County Layers MapServer (maps.desotocountyms.gov). 15 confirmed fields: PIN, ACREAGE, FULL_ADDR (site address), OWNER_NAME, SECOND_OWNER (co-owner), OWNER_ADDRESS, CITY, STATE, ZIP_CODE, DEED_BOOK1, DEED_PAGE1, WD_Link (warranty deed hyperlink), Tax_Info (hyperlink to county tax record), and Tax_Map (tax map hyperlink). Owner-name queries confirmed live 2026-05-15; SMITH returns Olive Branch MS addresses. WD_Link and Tax_Info are URL fields that deep-link directly into the county's deed and tax systems -- a convenience not common in Mississippi public layers. DeSoto County's GIS Hub at desotocounty-dcms-gis.hub.arcgis.com provides bulk downloads. The county tax assessor portal at desotocountyms.gov handles exemption and appeal records not surfaced in the REST layer. MIGRATED 2026-06-06: Layer 28 of Layers/MapServer was retired (ArcGIS 404) -- parcels now at CountyWebMap/Tax_Assessors_County_Web_Map/MapServer/29 (84,713 parcels; OWNER_NAME search re-verified live). Deed/tax hyperlink fields from the old layer are not confirmed on the new one.

DeSoto County's Tax Parcels layer exposes a parcel identifier (Parcel Identification Number), owner names (Owner Name), and address fields (Full Site Address). Use it for owner-name lookups and address-based parcel searches. 3 of 9 listed fields accept queries; the rest are returned on read but not indexed for search. Served as an ArcGIS MapServer layer, which supports query operations but not write operations; last verified 2026-06-06.

The sample query above is a working example you can paste into a browser tab to see the raw JSON response.Counties publish parcel data through their own ArcGIS Server installations, each with its own schema. One county uses APN, another uses PIN, a third uses PARCEL_ID. Some expose owner names; others keep them on a separate assessor's portal. The searchable fields list above reflects what DeSoto County actually publishes, not what you might expect from a national standard (there isn't one).

maps.desotocountyms.gov serves DeSoto County, Mississippi parcels over public ArcGIS REST, but, like most county servers, it may not send the CORS headers a browser needs for a cross-origin fetch. If a direct browser call fails, the layer still works from curl, Postman, or a server-side script; the UrbanKit parcel lookup tool proxies the request, so a search that succeeds there confirms the layer is genuinely public.
We last verified DeSoto County's MapServer layer on 2026-06-06. County GIS teams move services without notice, so if you hit a fresh 404, tell us and we'll re-check. Atlas entries are re-verified on a rolling basis.
DeSoto County's layer is hosted by the county on maps.desotocountyms.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but maps.desotocountyms.gov can throttle heavy automated traffic at the host level. Page through results with resultOffset / resultRecordCount and request only the fields you need. There's no API key and no charge from the county.
