What is an APN?
APN stands for Assessor's Parcel Number. It is a unique identifier used by local assessor offices to track parcels of land. Some areas may use terms like parcel ID, tax parcel number, or property identification number.
How APN lookup helps property research
An APN can help connect a parcel to public property records, tax records, ownership-related data, acreage, and county assessor information depending on the jurisdiction. Landy gives you a map-first way to find the APN for a lot and use it to cross reference county records.

Parcel identifiers across U.S. counties
APN formats vary widely across the United States. Some counties use short numeric IDs, others use longer dashed strings, and a few use legal descriptions for parcels that have never been assigned a tidy number. Landy accepts the parcel number as published by the relevant county and helps you locate it on the map.
