Assessor Parcel Number (APN) is a unique number assigned to each plot of land by a county tax assessor. The APN is based on formatting codes depending on the home’s location. The local government uses APNs to identify and keep track of land ownership for property tax purposes.

To find your home’s APN, go to your local county assessor’s office website and search for your address. There you can see information regarding lot size, home type, view information, property tax history, and the sale price history.
