An assessor's parcel number, or APN, is a number assigned to a property by the tax assessor of a particular jurisdiction that helps to identify that property. Different jurisdictions may use different names for the APN.

To find your APN, you can start by looking in your deed for the property. If for some reason you do not have the deed, you will need to contact your tax assessor’s office. Sometimes assessors may have an online portal for you to access your APN using your address or a county map.
