Parcel Number (APN)
The unique ID your county uses to identify your property on every tax record and appeal.
The Assessor’s Parcel Number (APN) — also called a parcel ID or folio number — is the unique identifier your county assigns to your land. It appears on your assessment notice, tax bill, and deed.
You’ll need it on every appeal form and when pulling your property record to check for errors. It’s the key that ties all your county’s data about the property together.
