School districts in Arizona
Arizona splits the two grade bands between separate districts over a large part of the state: 30% of its homes sit under an elementary district that stops before high school, with a separate secondary district taking over from there. That is why 162 of its 409 ZIP Code areas return a different set of districts for grade school than for high school. In 85396 (Buckeye), the most divided of them, Litchfield Elementary leads the elementary answer and Agua Fria Union High leads the high school one. The two districts that share the most ZIP Codes here are Washington Elementary and Glendale Union High, in 13 of them.
How many school districts are in Arizona?
214: the Census boundary file draws 214 school districts in Arizona that reach at least one ZIP Code area with homes, 97 unified, 102 elementary and 15 secondary. A ZIP Code here can sit in more than one of them, which is why a school district lookup by ZIP Code for Arizona lists them all: find your school district by ZIP code.
Two districts at one address
Arizona keeps 15 separate secondary districts — districts that pick students up partway through and run to the end of high school, over several elementary districts at once. Where one of those sits, an address has two district names and neither is wrong.

The most divided ZIP Code area in Arizona
ZIP Code area 85396 holds 13,232 homes, and 7 districts each take a meaningful share of them for elementary grades — Litchfield Elementary first at 36%, then Wickenburg Unified. A lookup that names the first is describing that share of the homes and silently not the 8,438 homes that remain.
Each percentage here is a share of the 13,232 homes counted in ZIP Code 85396, not the chance that any one address is in that district. Enrollment follows the street: two houses on opposite sides of the same road can be in different districts, and only the district office can say which.
Every track below is 35 cells long and stands for all 13,232 homes counted in ZIP Code 85396, so one cell is 378 homes, rounded to the nearest whole cell. Cells lit solid are the homes one district holds, and the unlit cells are the homes held by the other districts in the same list.
- Litchfield Elementary District4,794 of 13,232 homes36%
- Wickenburg Unified District4,015 of 13,232 homes30%
- Saddle Mountain Unified School District2,912 of 13,232 homes22%
- Buckeye Elementary District970 of 13,232 homes7.3%
- Palo Verde Elementary District517 of 13,232 homes3.9%
2 further districts reach into this area and hold 24 homes between them, under half a percent of the homes named at this level each.
For grade school, an answer of one district name would be wrong for 8,438 of the 13,232 here.
Where the high school answer in Arizona is missing from the file
Across the 409 ZIP Code areas in Arizona with homes in them, an answer of one district name misses 436,691 of the 3,060,477 homes they hold. The arithmetic understates it here: in 72 of those areas some homes have no high school district named at all, so the name that is right for the early grades is not wrong later — there is nothing there to be right about.
ZIP Code 85375 · Sun City West, Arizona is the case Arizona is known for: 13,907 of its 19,718 homes have no high school district named in the federal file, and Dysart Unified leads what is named for grade school. An answer of one name misses 16,066 homes there and the arrangement behind them.
In ZIP Code 85705 · Tucson, Arizona the largest district for grade school is Amphitheater Unified, and naming it alone misses 15,150 of the 28,336 homes counted there. For grade school the rest is 15,150 homes with Flowing Wells Unified and Tucson Unified.
In ZIP Code 85364 · Yuma, Arizona the largest district for grade school is Crane Elementary, and naming it alone misses 14,114 of the 30,243 homes counted there. For grade school the rest is 14,114 homes with Yuma Elementary.
Where a ZIP Code here names more than one district
Of the 409 ZIP Code areas in Arizona that the federal file names a district for, 259 name more than one school district.

What to do next
Ask the district office to confirm your street address: look on its site for a school locator, a find my school tool or an attendance zone map, or call the office.
A ZIP Code is a set of mail delivery routes, not a boundary: 259 of the 409 ZIP Code areas in Arizona with a district named for them are served by more than one school district, and the line between two of them runs along streets. Only the district can say which side of that line an address is on.
District websites and phone numbers here come from the NCES Common Core of Data directory, 2024-25 school year, filed under the same district ID as the Census boundary files. Where it lists no usable website, none is printed rather than guessed.
If a house purchase depends on the answer, ask the district itself for written confirmation of that exact address. A listing is not a district record, and neither is this page.
Where these numbers come from
The homes were counted in the 2020 Census and the district lines are the 2026 boundary file, so a fast-growing area may have changed since; ZIP Codes here are the Census Bureau's ZIP Code Tabulation Areas; a share is a share of homes, not the chance that one address is in a district; and a district is not a school attendance zone. Every source, file and caveat is on the method page.
