Understanding the Parcel Numbering System
Most counties use a numbering system to identify parcels for tax purposes. In Arizona, the Assessor's Parcel Number (APN) refers to the map book number and acts as the index for researching parcel information. Information is available for public viewing in most County Assessor's Offices and Recorder's Offices.
The Parcel Number usually consists of three parts. For example, APN 222-446-88 would mean Assessor's Book 222, Page 44 and Block 6 of that page, and parcel 88 of that block.
How to Locate Parcels
If street names are shown on the Plat Map, use the street index guide of another larger area map to locate the parcel.
If no street names are present, use the Township and Range numbers to locate the parcel.
The United States is divided into a large grid pattern of Townships and Ranges, approximately six miles wide. Each Township and Range intersection is comprised of 36 Sections of land. A single Section is one square mile in size.
Refer to the legend of another general area map to identify its Section, Township and Range markings. For example, N. 1/2 , Sec. 12, T.4S, R2E across the top of a Plat Map would mean the North Half of Section 12, Township 4 South, Range 2 East. Refer to the legend of another general area map to identify corresponding Section, Township and Range markings.
To obtain a variety of maps you may want to contact the counties' Assessor's Office and Planning Departments. These offices can help you find property information. You may also consider calling a title company to find more information about the land you are interested in acquiring. There are also many locations online that may help to determine more information on properties. The United States Department of the Interior, Geological Survey (U.S.G.S.) maps cover the entire country and come in several different scales. You can find many of these maps at local retail stores. Visit your local camping outlet, map dealer or book store.
