Each County is first divided into school districts. The school district boundaries are established and numbered by the County School Superintendent and many have been in place since territorial days. Each school district is given a County number; for example, school district #1 in Cochise County is Tombstone, school district #1 in Maricopa County is Phoenix Elementary and school district #1 in Navajo is Winslow Unified.

City boundaries are then overlaid onto the County divided into school districts so areas in and out of the cities are created in each school district. Next, special district boundaries are added creating another layer of districts to each County. Hundreds of combinations of districts must be identified, numbered and placed on a map by the Assessor.

Each unique area is identified with a number. When the Board of Supervisors sets the tax rates, a rate is established for each unique area. These identification numbers are referred to as “tax area codes.”  For example:

Area 0100 could be school district #1 and no other entities.
Area 0110 could be school district #1 inside city #1.
Area 0120 could be school district #1 inside city #2.
Area 0101 could be school district #1 outside any city but inside fire district #10.

The combinations are endless and as new subdivisions are created, cities annex property and new special districts are established, the Assessor is constantly adding new tax area code numbers and drawing new maps. Computerized mapping systems known as Geographic Information Systems (GIS) are enhancing the Assessor’s ability to meet the mapping responsibilities and speeding up the process.
