Enter any U.S. street address. We resolve it to your state and county via the U.S. Census Geocoder, then deep-link the public parcel REST API for that county so you can pull the actual APN, PIN, or owner record. No account, nothing stored.
A street address and a parcel number are two different identifiers for the same physical place. The address is what the post office uses; the parcel number is what your county tax assessor uses. To get from one to the other you have to cross the boundary between the postal address space and the county cadastral system.
The U.S. Census Bureau publishes a free, no-key geocoder that takes an address and returns the precise state + county FIPS code, plus the matched address (lowercase noise removed, street type normalized) and a latitude/longitude. That's the first hop.
From there the path depends on what your county publishes. 117 counties across 39 states expose a public ArcGIS REST API for parcels — that's the second hop. If your county is one of them, this tool deep-links to Parcel Lookup with the county's endpoint URL pre-filled, so you can search by address, owner, or APN against live county data.
If your county isn't indexed yet — most aren't — you'll see a handoff to your County Assessor's site. Many counties publish a web-based parcel viewer even without a REST API; we'll surface the most relevant one.

A parcel number — also called an Assessor's Parcel Number (APN), Property Index Number (PIN), or tax parcel ID — is the unique identifier your county assigns to a piece of real estate. You need it for property tax lookups, deed transfers, permit applications, public-notice mailings, and almost any government form that asks about a specific property. Every parcel has one; format varies by county.
You enter your street address. The U.S. Census Geocoder maps that address to a state and county. If your county publishes a public ArcGIS REST API for parcels — and 117 counties across 39 states do — the tool deep-links you straight into Parcel Lookup with that county's URL pre-filled. From there you can search by address, owner name, or APN against the live county data. If your county isn't indexed yet, the tool tells you where to look it up manually (usually the County Assessor's site).
No. The geocoding request goes through a stateless edge proxy on our side that calls the U.S. Census Geocoder and returns the response without logging. There is no account, no cookie, no analytics on what you typed. The browser tool that follows the deep-link also runs entirely client-side and queries the county REST endpoint directly.
Three reasons, in order of frequency: (1) the county isn't yet indexed in the UrbanKit atlas — we cover 117 counties and are growing; (2) the county's public REST layer indexes parcels by PIN only and not by address, so you'll need a PIN first (try the County Assessor's address search to get one); (3) the county's GIS server doesn't include CORS headers, so the browser tool can't fetch it directly. The Parcel Lookup page will tell you which case applies.
No. The County Assessor's website is the authoritative source — your county built it. This tool is a unified front-end across 117 counties so you don't have to learn each one. For the parcel record itself (legal description, tax history, owner name when not redacted), the Assessor's page is canonical. This tool gets you to the right county quickly and exposes the underlying REST endpoint so you (or your code) can integrate with it.
