What is an Assessors Parcel Number (APN)?
An Assessor’s Parcel Number is an series of ten numbers/digits that are used as a file number to inventory or identify property. • The first three numbers of the series are used to identify the map book the real property is located in. • The fourth number/digit is used for future expansion of the book series. Typically the entry here is 0 for land and improvement assessments. • The fifth and sixth digits are used to identify the page of the book the property is located on. • The seventh digit is used to identify the blocks of the page. Not all pages have blocks. In these cases a 0 appears in this space. • The eighth and ninth digits are used to identify the number assigned to a parcel. • The last or tenth digit is a suffix number used to identify the type of interest held (land only, land & mineral, or mineral only, etc.).
