Mississippi has 82 counties, each served by an elected Tax Assessor who handles both assessment and collection functions. There is no statewide parcel REST layer. The Mississippi Automated Resource Information System (MARIS) at gis.ms.gov is the state GIS clearinghouse, but it focuses on environmental and administrative layers, not a unified cadastral dataset. An important practical resource is the Mississippi Department of Environmental Quality's OPCGIS server (opcgis.deq.state.ms.us), which hosts parcel layers for multiple Mississippi counties under its Government folder — a government GIS server that has become a de facto parcel host for counties that published there rather than running their own ArcGIS Server. DeSoto County, Mississippi's fastest-growing county, operates its own server with a notably attribute-rich public layer including deed and tax record hyperlinks.
Mississippi has no statewide parcel aggregation service comparable to MassGIS or MnGeo. MARIS (gis.ms.gov) is the nominal state GIS authority but covers environmental and natural resource layers. The MDEQ OPCGIS server at opcgis.deq.state.ms.us/opcgis/rest/services/Government/ hosts parcel layers for Hinds, DeSoto, and other counties — an informal arrangement where counties chose that server as their publication point. DeSoto County operates its own ArcGIS Server at maps.desotocountyms.gov separately, with additional fields including deed hyperlinks not available through OPCGIS-hosted layers. Counties without public REST layers typically have browser-based assessor portals through county websites, but these lack documented APIs.
The Mississippi Department of Environmental Quality's GIS server under the Government/ services folder hosts parcel layers for Hinds and other counties. This reflects a historical publishing arrangement — MDEQ built GIS capacity early and some counties chose to publish their parcel data there rather than run their own infrastructure. The pattern for Hinds is /Government/HINDS_PARCELS/MapServer/0; other counties in the folder follow similar naming conventions. This is not a statewide coordinated program, so coverage is incomplete. If you are looking for a county not in the atlas, check the OPCGIS Government/ folder before assuming no public layer exists.
DeSoto County's Tax Parcels layer at maps.desotocountyms.gov/arcgis/rest/services/Layers/MapServer/28 includes WD_Link (warranty deed URL), Tax_Info (county tax record URL), and Tax_Map (tax map URL) as URL fields in each feature, deep-linking directly into county deed and tax systems. DEED_BOOK1 and DEED_PAGE1 are also present. OWNER_NAME and SECOND_OWNER (co-owner) are both in the schema and return data on public queries. This level of attribute exposure is not common in Mississippi public parcel layers and reflects the county's substantial growth pressure (Southaven, Olive Branch — Memphis metro south, pop. 185,000).
Mississippi parcel IDs have no statewide standard. Hinds County uses PARNO as the primary parcel number and PPIN as an alternate; DeSoto uses PIN. The PARNO field in Hinds follows a section-township-range-based convention. ALTPARNO in Hinds provides an alternate reference that may correspond to legacy records or sub-parcel splits. Do not assume Mississippi county parcel number fields share a name or format — query the layer's field schema before scripting. Cross-county Mississippi lookups require field-mapping each endpoint individually.
State capital county (Jackson, pop. 231,000). Parcel layer on MDEQ OPCGIS at opcgis.deq.state.ms.us under Government/HINDS_PARCELS/MapServer/0. OWNNAME, MAILADD1/2, MCITY1/2, SITEADD, and SCITY are all present. PARNO and PPIN serve as alternate parcel identifiers. Owner queries confirmed live as of May 2026.
Mississippi's fastest-growing county (Southaven, Olive Branch; Memphis metro south). Own ArcGIS Server at maps.desotocountyms.gov. Tax Parcels at layer 28. OWNER_NAME, SECOND_OWNER, DEED_BOOK1, DEED_PAGE1, WD_Link, and Tax_Info are all present — the most attribute-rich public Mississippi county layer in the atlas.
Hinds County owner search: ?where=UPPER(OWNNAME)+LIKE+UPPER('%25SMITH%25')&outFields=PARNO,PPIN,OWNNAME,MAILADD1,SITEADD,SCITY&returnGeometry=false&f=json&resultRecordCount=10 (base: opcgis.deq.state.ms.us/opcgis/rest/services/Government/HINDS_PARCELS/MapServer/0).

2 Mississippi counties are indexed in the UrbanKit atlas with verified public REST endpoints: Hinds and DeSoto. Each exposes an owner-name field you can search directly on the public layer.
Hinds and DeSoto expose an owner-name field on the public REST layer. Hinds, for example, uses the OWNNAME field — a case-insensitive search is ?where=UPPER(OWNNAME)%20LIKE%20UPPER('%25SMITH%25')&outFields=*&f=json. Open a county's page here for its full field list and a ready-to-run sample query.
Hinds publishes parcels at https://opcgis.deq.state.ms.us/opcgis/rest/services/Government/HINDS_PARCELS/MapServer/0 — a MapServer (layer 0). It indexes by Parcel Number, Alternate Parcel Number, PPIN, and Owner Name. Owner-name search: UPPER(OWNNAME) LIKE UPPER('%25SMITH%25').
Mississippi's indexed counties (Hinds and DeSoto) publish county-hosted ArcGIS MapServer layers. MapServer supports the same /query operation for owner, parcel-ID, and address lookups as FeatureServer — for read-only parcel lookups the two are interchangeable.
