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).

services8.arcgis.com serves Oklahoma County, Oklahoma 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 Oklahoma County's FeatureServer layer on 2026-06-05. 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.
Oklahoma County's layer is hosted on Esri ArcGIS Online. Public ArcGIS endpoints rarely rate-limit individual reads, but services8.arcgis.com 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.
