https://services.nconemap.gov/secure/rest/services/NC1Map_Parcels/MapServer/1Field by field, whether any endpoint we index for Onslow County answers it, and the evidence for each. We only call a field restricted when there is a stated reason we can cite. Everything else here is a fact about the services we index, not a claim about the law.

Onslow County, North Carolina (Jacksonville; FIPS 37133) is served via the NC OneMap statewide parcel aggregation (NC1Map_Parcels), the same layer as the other North Carolina records, filtered by cntyname = 'Onslow' (95,297 rows on 2026-10-10, the same count as cntyfips = '133'). Owner is populated on 95,262 rows (99.96%), situs on 95,260 (99.96%) and mailing on 94,945 (99.6%). scity is populated on 95,254 rows. Owner reads 'UNKNOWN OWNER' on 3 rows, a placeholder rather than a name. Key fields: parno (parcel number), ownname/ownname2 (owner names), siteadd (site address), scity, mailadd/mcity/mstate/mzip (mailing address), parval, landval, improvval, gisacres, saledate, cntyname, cntyfips. The layer publishes no editingInfo and revisedate is null on every Onslow row, so the vintage of this county's roll cannot be dated from the service: there is no reliable per-county date. The layer allows 5,000 rows per page with pagination and answers cross-origin requests (the server echoes the request Origin). The service lives under /secure/rest and sets an AGS_ROLES cookie, as it does for the other North Carolina records. Verified 2026-10-10 with an Origin: https://urbankitstudio.com header: an owner SMITH search matches 1,041 rows; the control county Forsyth (cntyfips '067') answers the same queries with 166,755 rows and 166,378 owners.

Onslow County's Parcels (polys) layer exposes a parcel identifier (Parcel Number), owner names (Owner Name), and address fields (Site Address). Use it for owner-name lookups and address-based parcel searches. 4 of 11 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 2026-10-10.
/query?where=…&outFields=*&f=jsonto the URL. 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 Onslow County actually publishes, not what you might expect from a national standard (there isn't one).

services.nconemap.gov serves Onslow County, North Carolina 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 Onslow County's MapServer layer on 2026-10-10. 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.
Onslow County's layer is hosted by the county on services.nconemap.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but services.nconemap.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.
