Public ArcGIS MapServer endpoint for Guilford County parcel data. URL, supported fields, and a working sample query, copy it, or open it directly in the UrbanKit parcel lookup tool.
This page is the endpoint reference. If you came here to find a specific property, the Guilford County parcel search runs this same layer in your browser, no account and no API key.

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.

Guilford County (Greensboro and High Point metro, pop. 540,000) is served via the NC1Map statewide parcel aggregation (services.gis.nc.gov). Filter by cntyfips='081'. The same field schema applies as other NC1Map counties: ownname/ownname2, siteadd/scity/szip, mailadd/mcity, parval, landval, improvval, parusecode/parusedesc, saledate, and legdecfull. Guilford covers two large municipalities -- Greensboro and High Point -- whose parcel data are both captured in this single county layer; the scity field distinguishes them. Guilford County GIS Hub (gcgis.guilfordcountync.gov) exposes boundary and road layers but not the full parcel-plus-owner REST path; NC1Map remains the only public REST route for owner-level queries. Verified 2026-05-15: cntyfips='081' returns Greensboro and High Point addresses. Quarterly update cycle from county to GICC may lag recent deed recordings by up to 3 months.

Guilford 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 6 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 2026-05-15.
/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 Guilford County actually publishes, not what you might expect from a national standard (there isn't one).

services.nconemap.gov serves Guilford 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 Guilford County's MapServer layer on 2026-05-15. 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.
Guilford 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.
