How to Find Your Parcel Number (APN) for Any Piece of Land
Updated September 2026 by Cooper and Jennifer Best, Best Land Holdings.
Every piece of land in the country has an ID number assigned by the county. It is the fastest way for a buyer, title company or tax office to find exactly which property you mean, and it is the one thing we ask for to start an offer.
It goes by many names
Depending on the state and county, your parcel number may be called an APN (assessor's parcel number), PIN (parcel identification number), parcel ID, tax ID, tax map number, account number or folio number. They all mean the same thing for our purposes.
Four ways to find it
- Your property tax bill. The parcel number is printed on every annual tax bill and usually on the county's online tax payment page.
- The county property search. Search the county assessor, appraiser, property valuation or tax office website by owner name. The result shows the parcel number, acreage and a map.
- The county GIS map. Most counties have an online parcel map. Zoom to the land and click it to see the parcel number and owner.
- Your deed or closing papers. Many deeds and settlement statements list the parcel number near the legal description.
Still can't find it?
Call the county tax office with the owner's name. They can usually look it up in a minute. Or just send us the county, state and owner name and we will find it for you.
Why buyers ask for it
With a parcel number we can pull the exact boundaries, acreage, road access, flood zone, tax status and nearby sales. That is how we can give you a real written offer, usually within 48 hours, instead of a guess.
Frequently asked questions
Is the parcel number the same as the address?
No. Much vacant land has no street address at all. The parcel number is the reliable identifier.
Can one property have more than one parcel number?
Yes. Larger tracts are sometimes split into several parcels for tax purposes. Send us all of them.
Is it safe to share my parcel number?
Yes. Parcel numbers and ownership are public records available on the county website.
