Glendale Union High School District

Arizona · runs grade 9 through grade 12

NCES ID 0403450 · guhsdaz.org · (623) 435-6000

There is no ZIP Code area where Glendale Union High is the only school district serving the homes. It holds a real share in 16 of them and shares every one, with 10 different districts in total. A lookup that returns a single district name for any of those ZIP Codes is guessing which side of a line an address falls on.

It never has a ZIP Code to itself

At 2,343 homes to the square mile this is city territory, and district lines in a city follow streets. Glendale Union High covers 59 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 85029 this district holds 100% of the homes; in 85033 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

Glendale Union High is the largest district in 9 ZIP Code areas. Answer with its name alone and the high school answer misses 28,828 of the 148,856 homes those areas hold — though in 1 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.

Glendale Union High holds 9,684 of the 18,034 homes in ZIP Code 85020 · Phoenix, Arizona, so its name is the right high school answer for most of the area and the wrong one for the rest: 8,350 homes with Phoenix Union High and Paradise Valley Unified.

The elementary districts that feed it

Students arrive at Glendale Union High from 6 districts that run the lower grades in the same ZIP Code areas — Washington Elementary, which sends 64%, Glendale Elementary, which sends 25% and Alhambra Elementary, which sends 6.6%. 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.

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

Glendale Union High shares ZIP Code areas with 10 different districts. The most frequent are Washington Elementary, Phoenix Union High, Alhambra Elementary and Glendale Elementary. In a neighborhood this crowded the question is not which district serves the ZIP Code but which side of which street an address is on.

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 16 of the 18 ZIP Code areas Glendale 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.
