Property
Parcel Number
The unique ID a county assigns to a piece of land. Also called APN (Assessor's Parcel Number), PIN, or folio number.
The parcel number is the reliable way to identify a tax sale property. Addresses can be missing, shared, or wrong, especially for vacant land.
Use the parcel number to look up the assessor record, the parcel map, and recorded documents before bidding.
