Public ArcGIS FeatureServer endpoint for Statewide 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 Statewide parcel search runs this same layer in your browser, no account and no API key.
Search Statewide parcels →https://arcgisserver.digital.mass.gov/arcgisserver/rest/services/AGOL/MassachusettsPropertyTaxParcels/FeatureServer/1Field by field, whether any endpoint we index for Statewide 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 | No endpoint we index for this county documents this field, so a query cannot ask for it. That is a fact about the services we index, not a legal restriction, and not a statement that the county holds no such record. Where to request it. |

MassGIS Level 3 (L3) Standardized Assessors' Parcel data, a single statewide service covering all 351 Massachusetts municipalities including all 6 target counties: Suffolk (Boston), Middlesex, Worcester, Norfolk, Essex, and Plymouth. Parcels are organized by municipality (TOWN_ID numeric code), not by county. To filter by county: Suffolk towns include Boston (274), Chelsea (54), Revere (223), Winthrop (349); Middlesex includes Cambridge (49), Lowell (168), Newton (195); use the MassGIS town-code lookup at mass.gov for the full list. Two-layer workflow: layer 1 (Tax Parcels) carries polygon geometry and parcel ID; layer 4 (L3_ASSESS table, no geometry) carries owner name, address, and assessment data, join on LOC_ID. OWNER_NAME field is public.

Statewide's Tax Parcels layer exposes a parcel identifier (Map-Parcel Identifier) and owner names (Town/City Numeric ID (filter by municipality)). Use it for owner-name lookups and PIN-keyed record pulls. 3 of 5 listed fields accept queries; the rest are returned on read but not indexed for search. Served as an ArcGIS FeatureServer layer, so edits and applyEdits operations are technically exposed (read access only is published here); 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 Statewide actually publishes, not what you might expect from a national standard (there isn't one).
For background, see What is an APN?
arcgisserver.digital.mass.gov serves Statewide, Massachusetts 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 Statewide's FeatureServer 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.
Statewide's layer is hosted by the county on arcgisserver.digital.mass.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but arcgisserver.digital.mass.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.
