Oklahoma County is Oklahoma's most populous county (pop. 810,000; county seat Oklahoma City). The TaxParcelsPublics_view FeatureServer is hosted on ArcGIS Online (services8.arcgis.com, org ID euhkr1dAJeQBIjV0) and published via the OK County GIS Hub at ok-county-gis-hub-ok-co.hub.arcgis.com. Live query confirmed 336,922 parcels and owner-name exposure. Key fields: accountno (R-prefixed account number, e.g. 'R189878000'), name1/name2/name3 (up to three owners), mailingaddress1, city (mailing city), location (combined property address when populated, e.g. '17622 N INDIAN MERIDIAN RD OKLAHOMA CITY'), locationcity (property city), propertyid (numeric internal ID), taxdistrict, taxdistrictname, currentmarket, currentassessed, currenttaxable, landvalue, legal (legal description), subname, lot, block, section, township, range, acreage. Note: location and locationcity fields may be null for some rural parcels — when null, use legal/section/township/range for location. The former county ArcGIS Server at oklahomacounty.geocortex.com is no longer reachable (DNS fails as of 2026-06); the ArcGIS Online hosted view is the current canonical public layer. Oklahoma County Assessor portal at assessor.oklahomacounty.org provides the full record with appeals and valuation history.

Oklahoma County's TaxParcelPublic layer exposes a parcel identifier (Account Number (APN)), owner names (Owner Name (Primary), Owner Name 2, Owner Name 3), and address fields (Property Address, Mailing Address). Use it for owner-name lookups and address-based parcel searches. All 7 listed fields accept queries. Served as an ArcGIS FeatureServer layer, so edits and applyEdits operations are technically exposed (read access only is published here); last verified 2026-06-05.

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 Oklahoma County actually publishes — not what you might expect from a national standard (there isn't one).
For background, see What is an APN?
Many county servers allow public reads but block browser cross-origin requests. The UrbanKit parcel lookup tool fetches directly from your browser; if it works there, the layer is technically public. For your own integration, you may need a same-origin proxy or server-side fetch.
Possibly — counties move services without warning. We re-verify entries weekly and flag stale ones. If you're seeing a fresh 404, please let us know and we'll update the listing.
Most are. Public ArcGIS layers don't typically rate-limit individual reads, but heavy programmatic use can trigger throttling at the host level. Be respectful — query what you need.
