Phoenix Union High School District

It never has a ZIP Code to itself

At 1,554 homes to the square mile this is city territory, and district lines in a city follow streets. Phoenix Union High covers 174 square miles in all — small enough that a single ZIP Code area can hold most of it, and several ZIP Codes can cut across it.

The ZIP Code areas it reaches

The spread is the thing to notice. In 85008 this district holds 100% of the homes; in 85026 it holds no homes at all. Same district, opposite answers, and a lookup that names it without the share tells the second household the same thing as the first.

What one name misses, and what changes later

Phoenix Union High is the largest district in 22 ZIP Code areas. Answer with its name alone and the high school answer misses 28,529 of the 282,011 homes those areas hold — though in 12 of them it holds every home there is for high school. The count is homes, not addresses, and it is the number no lookup prints.

Phoenix Union High holds 10,055 of the 19,872 homes in ZIP Code 85018 · Phoenix, Arizona, so its name is the right high school answer for most of the area and the wrong one for the rest: 9,817 homes with Scottsdale Unified.

ZIP Code 85017 · Phoenix, Arizona is a two-district area for high school: 8,503 of its 12,943 homes are inside Phoenix Union High, and the other 4,440 homes are with Glendale Union High. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 85015 · Phoenix, Arizona the split runs 13,537 to 3,868 and the larger part is Phoenix Union High's: the rest is 3,868 homes with Glendale Union High.

In ZIP Code 85339 · Phoenix, Arizona the split runs 13,329 to 876 and the larger part is Phoenix Union High's: the rest is 137 homes with Tolleson Union High, 39 homes in districts too small to name here and 700 homes in no high school district in the federal file.

Phoenix Union High holds all 5,414 homes counted for high school in ZIP Code 85003 · Phoenix, Arizona, and no other high school district holds a share worth naming. For grade school the same homes are named for Phoenix Elementary (5,236 homes) and Osborn Elementary (178 homes), so a single name answers only one of the two questions there.

In ZIP Code 85020 · Phoenix, Arizona this district is one name among 5. Glendale Union High leads with the largest share and Phoenix Union High holds 5,925 of the 18,034 homes counted there; no single name describes that area at all.

Phoenix Union High holds 5,647 of the 24,657 homes for high school in ZIP Code 85301 · Glendale, Arizona, behind Glendale Union High at that level. For grade school the area is named for Glendale Elementary (19,008 homes), Alhambra Elementary (5,647 homes) and 2 homes in a district under half a percent.

ZIP Code 85043 · Phoenix, Arizona repeats the pattern with 5 names holding a real share: 2,588 of its 10,417 homes are Phoenix Union High's, and the other 7,829 are not.

The elementary districts that feed it

Students arrive at Phoenix Union High from 6 districts that run the lower grades in the same ZIP Code areas — Roosevelt Elementary, which sends 13%, Madison Elementary, which sends 12% and Cartwright Elementary, which sends 11%. An address on that ground belongs to two districts at once, one for grade school and this one for high school, and neither name is the whole answer.

• Roosevelt Elementary District13% of Phoenix Union High's homes come from here
• Madison Elementary District12% of Phoenix Union High's homes come from here
• Cartwright Elementary District11% of Phoenix Union High's homes come from here
• Creighton Elementary District11% of Phoenix Union High's homes come from here

This list is an estimate, names as well as percentages. The snapshot behind this site keeps the homes each district holds in each ZIP Code area, not the pair of districts on each census block, so a district is listed here when it runs the other band in a ZIP Code area this one shares, and each percentage spreads that area's homes across those districts in proportion to the share each holds there. Unified districts are left out: a block in a unified district belongs to no elementary or secondary district. Read the percentages as the size of the crossing, not as a count of houses.

Who it shares ZIP Codes with

Phoenix Union High shares ZIP Code areas with 25 different districts. The most frequent are Osborn Elementary, Phoenix Elementary, Glendale Union High and Madison Elementary.

Have a street address?

A ZIP Code names every district that can serve the area; a street address settles which one serves a home. The Census Bureau geocoder takes an exact address and returns its school districts from the current boundary files, free and with no account.

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: in 30 of the 31 ZIP Code areas Phoenix Union High reaches, at least one other district holds a real share of the homes as well, and the line between 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.
