what is an apn number for property

[ReidLee]

An APN, or Assessor's Parcel Number, is a unique identifier assigned to a property by the local tax assessor for records and tax purposes. It tracks ownership, value, zoning, and other property details, and is usually on tax bills. APN formats vary by location, and it’s vital for real estate transactions and public records. It may also be called a Property Identification Number (PIN) or Sidwell Number.
