To find a Parcel ID for your property online, go to your county assessor’s website and search by street address, owner name, or by clicking the property on the county’s GIS map viewer. The number, sometimes called an Assessor’s Parcel Number (APN), Property Identification Number (PIN), or tax map number, will appear on the results page along with the assessed value and tax history. If you already have the deed, tax bill, or title report in front of you, the number is almost certainly printed on it and you can skip the search entirely.
Search the County Assessor’s Website
Nearly every county in the country runs an online property search through the assessor’s or tax collector’s office. To find yours, search the county name plus “assessor’s office,” “parcel viewer,” or “GIS maps.”1U.S. Geological Survey. Authoritative Source: Parcel Viewer If nothing turns up at the county level, check whether your state hosts a statewide parcel viewer through its GIS or mapping department.
Once the portal loads, you’ll usually see fields for address, owner name, and parcel number. Enter whatever you have. An address search is the most direct route. The results page displays the Parcel ID next to the assessed value, tax history, lot size, and often building details.
Searching by owner name works too, but if the person owns more than one property you’ll get multiple hits. Use the address or the map location to pick out the right one.
Use the County’s GIS Map Viewer
Many counties offer an interactive GIS map alongside or in place of the standard search form. These viewers let you zoom into an area and click directly on a parcel to pull up its ID and property details.
Map tools are especially useful when you can see the property on a satellite image but don’t know its exact address. You navigate visually and click the lot. Parcel boundaries are drawn as overlays on the aerial imagery, so you can confirm you’re on the right piece of land before writing the number down.
Check Documents You Already Have
If the property is yours, the fastest way to get the Parcel ID isn’t online at all. It’s already printed on paperwork you own.
- Your annual property tax bill displays the Parcel ID near the top, next to the owner name and property location. Most counties will mail a duplicate or let you access old bills online if you’ve lost the original.
- The deed you received when you bought the property includes the Parcel ID, usually near or within the legal description.
- If you bought title insurance, the preliminary title report issued before closing lists the parcel number along with the legal description and any recorded encumbrances.
- Some lenders print the parcel number on periodic mortgage statements or on the original loan documents.
Any of these gives you the number in seconds. If you’re looking up a Parcel ID for someone else’s property, you won’t have their paperwork and the online methods are the way in.
When the Online Search Turns Up Nothing
Online tools occasionally miss a property. The usual reasons: the address was recently assigned or changed, the property was recently subdivided and the new parcels haven’t been indexed yet, or the search field wants a specific address format you’re not using.
Try variations before giving up. Drop the directional prefix. Spell out “Street” instead of abbreviating it. Search by owner name instead of address. If the property still doesn’t appear, the record exists somewhere in the county’s system, but the public search tool isn’t reaching it. Call the assessor’s office directly.
Finding a Parcel ID for Vacant or Rural Land
Vacant lots and rural acreage often have no street address at all, which makes the standard search useless. This is where most people get stuck. You have several workarounds.
If you have a deed or any document with the property’s legal description, use the description to search the county records. Many assessor sites accept legal description searches, and staff can look it up over the phone if the site doesn’t. The legal description references townships, ranges, sections, lots, and blocks, all of which map directly to how the assessor organizes parcel data.
A GIS map viewer solves most of the rest. Navigate to the approximate location using roads, landmarks, or neighboring properties you can identify, then click on the parcel. Even land in the middle of nowhere has visible parcel boundary lines drawn on the county GIS map. If you have GPS coordinates, some viewers let you enter them directly to jump to the spot.
You can also work backward from adjacent parcels. If you know the Parcel ID of a neighboring property, the assessor’s records or GIS map will show the surrounding parcels, and you can pick yours out by its position. Tax records are tied to parcel numbers rather than street addresses, so the county always has a record. You just need a different way in.
Call the Assessor’s Office When Online Fails
If the online tools don’t get you there, a phone call or visit will. The assessor, tax collector, and recorder’s offices all keep property records and can look up a Parcel ID for you. Give them whatever identifying details you have: address, owner name, legal description, or a description of the property’s location relative to landmarks or cross streets.
Parcel IDs are public information. You don’t need to prove you own the property, and most counties provide the number at no charge. Some offices handle lookups over the phone in minutes. Larger jurisdictions may point you back to their website or ask for a written request. A certified copy of a property record costs a small recording fee, typically under $10.
A handful of states restrict online display of owner names or other identifying details without the owner’s written permission. The parcel number itself is still public in those places, but you may run into limits when searching by owner name online. Calling the office usually clears it up.
What a Parcel ID Is, and What It Isn’t
A Parcel ID is a numerical code the county assigns to a specific piece of land for tax and record-keeping. Different jurisdictions call it different things (APN, PIN, tax map number, tax ID), but the function is the same: it links a defined piece of land to its tax records, ownership history, and assessed value.
A Parcel ID is not a street address. A street address tells a mail carrier where to deliver packages. A Parcel ID tells the county which piece of land is being taxed or transferred. One building might sit on two parcels, each with its own number. A vacant lot might have a Parcel ID but no street address. Neighboring parcels owned by the same person can sometimes be combined under a single number.
A Parcel ID is also not a legal description. The legal description, written in metes-and-bounds language or referencing a recorded plat, is what actually defines the property’s boundaries in a legal sense. If a deed shows a parcel number that conflicts with the legal description, the legal description controls. The Bureau of Land Management defines a legally sufficient property description as one that “can be located on the ground by a land surveyor,” which a parcel number alone cannot do.2Bureau of Land Management. Specifications for Descriptions of Land The parcel number is an administrative shortcut, useful for finding records, not for defining boundaries.
