https://gis.rgv911.org/server/rest/services/RGV911_Web_Apps_MIL1/MapServer/7Field by field, whether any endpoint we index for Hidalgo 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.

Hidalgo County, Texas (county seat Edinburg; FIPS 48215) was asked for through the free tools. The parcels are Hidalgo County Appraisal District data, published as layer 7 ('Hidalgo Parcels') of the RGV911_Web_Apps_MIL1 MapServer on the server of RGV911, the regional emergency-communications district, not by the appraisal district itself: 334,098 parcels on 2026-10-14, 331,009 of them with an owner. The owner is file_as_name; the parcel id is prop_id (an integer) with the CAD geographic id geo_id. SITUS IS ONE FULL STRING: the situs column holds the whole site address with city and state in one value (for example a house number, street, city name and 'TX'), on 330,212 rows, so an address LIKE on a street word or a '123 MAIN' prefix works (the two largest cities, Edinburg and McAllen, show up in about 41,600 and 40,700 rows). MAILING IS THE STREET LINE ONLY: addr_line1 holds the owner mailing street or PO Box line on 330,779 rows, and addr_line2, addr_line3, addr_city, addr_state and zip are published but empty (0 rows), so the mailing city, state and ZIP are NOT available from this layer; the registry lists addr_line1 as the mailing column for that reason. CONFIDENTIAL OWNERS: 1 row reads exactly 'CONFIDENTIAL' in file_as_name; Texas Tax Code 25.025 lets protected persons have their information withheld, and that word is a placeholder, not an owner name. CORS answers Access-Control-Allow-Origin with the calling origin (checked with Origin https://urbankitstudio.com). maxRecordCount is 2000 with pagination; the layer is Web Mercator (wkid 102100) and a point query with inSR 4326 at the county courthouse in Edinburg returned one parcel whose situs is 100 N Closner Blvd, Edinburg. Currency: the newest last_edited_date and created_date in the layer are both 2026-08-14 (the layer document carries no editingInfo, so this is a row-level date, not a publish date); no tax-year column exists, so the roll year is not stated. LICENSE AND DURABILITY: no license text; the host is a third-party public agency that republishes the district roll for 911 addressing, so the layer index (7) and the service name can change when RGV911 republishes its web-app map; re-resolve from the RGV911 service directory if the liveness probe flags it. The contact is the appraisal district, which owns the underlying roll. Verified 2026-10-14: a count, resultRecordCount=10, an owner LIKE query (360 rows for %SMITH%) and a point query.

Hidalgo County's Hidalgo Parcels layer exposes a parcel identifier (Parcel ID (Hidalgo CAD property id)), owner names (Owner Name, Owner Mailing Address (street line)), and address fields (Situs Address). Use it for owner-name lookups and address-based parcel searches. 6 of 8 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 2026-10-14.
/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 Hidalgo County actually publishes, not what you might expect from a national standard (there isn't one).

gis.rgv911.org serves Hidalgo County, Texas 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 Hidalgo County's MapServer layer on 2026-10-14. 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.
Hidalgo County's layer is hosted by the county on gis.rgv911.org. Public ArcGIS endpoints rarely rate-limit individual reads, but gis.rgv911.org 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.
