700 of the 14,205 homes here have no high school district named in the federal file.

Each percentage here is a share of the 14,205 homes counted in ZIP Code 85339, 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.

The districts named for the early grades in ZIP Code 85339, Phoenix, Arizona are not the districts named for high school, and the set changes in both directions: one district arrives for high school that no elementary answer names, and another runs the early grades and stops. 5 districts hold the 14,205 homes counted here between them, and Laveen Elementary is the largest by homes. The largest share is high enough that one name is right for most of the homes counted and wrong for the other 876: 787 homes with Roosevelt Elementary and Union Elementary, 39 homes in districts too small to name here and 700 homes in no grade school district in the federal file.

Three districts share the early grades

3 districts hold a measurable share of ZIP Code 85339 at this level. Laveen Elementary is the largest with 12,679 homes; the smallest of them holds 137 homes. Laveen Elementary, Roosevelt Elementary and Union Elementary are named here for grade school and not for high school.

Every track below is 35 cells long and stands for all 14,205 homes counted in ZIP Code 85339, so one cell is 406 homes, rounded to the nearest whole cell. Cells lit solid are the homes one district holds; the hatched cells at the end of a track are homes that no district of that kind is drawn to serve at all.

  • Roosevelt Elementary District650 of 14,205 homes4.6%
  • Union Elementary District137 of 14,205 homes1.0%

700 of the 14,205 homes here have no grade school district named in the federal file.

Below half a percent at the grade school level: Kyrene Elementary District, Sacaton Elementary District and Fowler Elementary District, and 3 more hold 39 homes between them, which is why they are counted under the list rather than inside it. A lookup that named them alongside the districts above would be listing a boundary crossing rather than an answer.

High school is split between two districts

2 districts hold a measurable share of ZIP Code 85339 at this level. Phoenix Union High is the largest with 13,329 homes; the smallest of them holds 137 homes. Phoenix Union High and Tolleson Union High are named here for high school and not for the early grades.

  • Phoenix Union High School District13,329 of 14,205 homes94%
  • Tolleson Union High School District137 of 14,205 homes1.0%

700 of the 14,205 homes here have no high school district named in the federal file.

Below half a percent at the high school level: Tempe Union High School District, Casa Grande Union High School District and Maricopa Unified School District hold 39 homes between them, which is why they are counted under the list rather than inside it. A lookup that named them alongside the districts above would be listing a boundary crossing rather than an answer.

The set of names changes in both directions

Phoenix Union High and Tolleson Union High are named for high school here and for no elementary grades, and Laveen Elementary, Roosevelt Elementary and Union Elementary run the early grades and no more. An address on the wrong street can therefore change district at the change of grade and land in a district that was never part of its elementary answer, while a neighbor two blocks away keeps one name the whole way through.

What one district name costs in 85339

A lookup that answers ZIP Code 85339 with one district name has to pick one of the names below and drop the rest. Measured against the 14,205 homes counted here, for the early grades it is wrong for 1,526 homes and for high school it is wrong for 876 homes. That is the whole difference between this page and a one-line answer: the same federal file, read to the end instead of to the first row.

The districts that reach into 85339

The districts named above are not alike in size or in reach. Phoenix Union High touches 31 ZIP Code areas in all and holds 13,329 homes inside this one; Laveen Elementary touches 3 areas. Not one of them is ever the only district in a ZIP Code area anywhere in the country: every postal area they touch, they share with somebody. 1 of them has a page here listing every ZIP Code area it reaches.

Where Laveen Elementary goes from here

Laveen Elementary District runs pre-K through grade 8, and it is the only school district serving 0 of the 3 ZIP Code areas it touches, shares 2 more with neighbors, and holds under half a percent of the homes in the remaining 1. Inside its own boundary it holds 15,581 homes over 28 square miles; the part of it counted in ZIP Code 85339 is 12,679 of those. The district it shares the most postal ground with is Phoenix Union High School District, across 2 ZIP Code areas. Its thinnest measured foothold is elsewhere: in ZIP Code area 85041 it holds 2,902 of 18,934 homes, or 15% of them.

Look up 85339 again, or look up another ZIP Code

The lookup holds every ZIP Code area in the country with homes in it, including the ones with no page of their own. Opening it at 85339 recomputes the same 14,205 homes from the same snapshot, and typing five other digits answers for somewhere else. Nothing here is fetched from anywhere while you read: the whole index travels with the lookup page itself.

What to do next

Ask the district office to confirm your street address. A district settles that question on its own site: look for a school locator, a find my school tool, or an attendance zone map. Where there is none, ask the office itself.

A ZIP Code is a set of mail delivery routes, not a boundary: 876 of the 14,205 homes counted in 85339 sit outside the district holding the most of them, and the line between the two runs along streets rather than around the postal area.

This site links to no district website. None of the federal files it is built from publishes one, and a guessed address is worse than none. It is the district office, not a search engine, that settles an address.

What this site can hand you instead:

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.

What this cannot tell you

The homes were counted in the 2020 Census and the district lines are the 2026 boundary file. Nothing on this page adjusts one to the other. Where houses have been built or cleared since the count, a share here describes the place as it was counted rather than as it stands today, and in the fastest-growing ZIP Code areas that gap is the largest single source of error on this site.

A share on this page is a share of the homes in the ZIP Code area, not a probability for any particular address. Enrollment is decided by street address, and a district may run magnet, charter or choice programs that ignore the boundary entirely. If a decision depends on the answer, the district office is the only authority; this page shows what the federal boundary files say and when they were published.

A district boundary is not a school attendance zone. This site never says which school an address is assigned to: no current national dataset of attendance zones exists, and the district draws them itself. Nor is anything here endorsed or certified by the Census Bureau; we use their published files, and that is the whole of the relationship.

A ZIP Code is a set of mail delivery routes, not an area. What is mapped here is the Census Bureau's ZIP Code Tabulation Area, the closest published approximation to it. The two are not identical, and a handful of ZIP Codes used only for post office boxes or single buildings have no tabulation area at all.

Where these numbers come from

School district boundaries come from the Census Bureau's Census Geographic Relationship File, current 2026 vintage, which assigns every census block to a unified district or to an elementary and a secondary district. Homes and residents in each block come from the 2020 Census Redistricting Data (PL 94-171), H1_001 and P1_001. The ZIP Code areas come from the same Geographic Relationship File, block to ZIP Code Tabulation Area. District names and grade ranges come from the Census Gazetteer 2025, with 2020 for districts no longer listed.

The place name printed beside a ZIP Code comes from the Census 2020 ZIP Code Tabulation Area relationship files: place, county subdivision and county, taken 2026-09-06. It is a label rather than a measurement: the Census Bureau does not publish which post office a ZIP Code belongs to, so the place named is the one covering the most land inside the area, not the city the Postal Service prints on an envelope.

Everything else on this page — the shares, the counts of districts per ZIP, the comparison between the two grade bands, the rankings — is computed here from those files. The source publishes none of it. Snapshot taken 2026-09-03.
