Public ArcGIS MapServer endpoint for Northampton 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 Northampton County parcel search runs this same layer in your browser, no account and no API key.

https://services.nconemap.gov/secure/rest/services/NC1Map_Parcels/MapServer/1Field by field, whether any endpoint we index for Northampton 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.

| Owner mailing address | Not published | mailadd is filled on 100.0% of Northampton County's rows, but only 21 of 25 sampled values on 2026-10-17 were street-like (a house number or a PO Box). The atlas requires 90%, so no mailing field is listed. Owner names and site addresses are unaffected. Where to request it. |

Northampton County, North Carolina (FIPS 37131). Served by NC OneMap's statewide parcel layer (NC1Map_Parcels MapServer layer 1, "Parcels (polys)", on services.nconemap.gov), which the NC Center for Geographic Information and Analysis (NC CGIA) compiles through the NC Integrated Cadastral Data Exchange by transforming each county's assessor data; credit the Northampton County tax assessor's office and NC OneMap (NC CGIA). The layer carries all 100 counties (5,938,900 rows), so every attribute search here is scoped with cntyname = 'Northampton' (20,504 rows read 2026-10-17; cntyfips = '131' selects the same rows). Informational only and not a legal record: verify with the Northampton County tax office, whose roll is the authoritative source. The layer pages with resultOffset and resultRecordCount and returns up to 5,000 rows per request; the county-scoped parcel-number lookups we ran on 2026-10-17 answered in 2.0 to 2.8 s. Share of the county's rows filled, read 2026-10-17: parno 98.9%, ownname 98.9%, siteadd 52.5%, parval above zero 98.8%, gisacres above zero 98.2%; not listed because under 50%: scity 0.0%, szip 0.0%, parusedesc 0.0%. ownname is blank (an empty or all-space string) on 1.1% of rows (218), so those parcels cannot be found by owner name. Mailing columns not mapped; the owner mailing address capability record says why. No field in the layer dates the county's roll; the state transformed this county's data in June 2025 (transfdate), so lastVerified is our probe date, not a data date. CORS: the server echoes the request Origin, so browser tools call it directly.

Northampton 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. 3 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 2026-10-17.
/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 Northampton County actually publishes, not what you might expect from a national standard (there isn't one).

services.nconemap.gov serves Northampton 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 Northampton County's MapServer layer on 2026-10-17. 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.
Northampton 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.
