ZIP Code 85345 · Peoria, Arizona
Maricopa County · 23,455 counted · 3 districts
Each percentage here is a share of the 23,455 homes counted in ZIP Code 85345, 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 85345, Peoria, Arizona are not the districts named for high school, and the set changes in both directions: 1 district arrives for high school only, 1 runs the early grades and stops, and 1 serves both bands. 3 districts hold the 23,455 homes counted here between them, and Peoria Unified 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 578: 489 homes with Glendale Elementary and 89 homes in a district too small to name here.
The early grades are split between two districts
2 districts hold a measurable share of ZIP Code 85345 at this level. Peoria Unified is the largest with 22,877 homes; the smallest of them holds 489 homes. Glendale Elementary is named here for grade school and not for high school.

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.
Check an exact address with the Census Geocoder
Then confirm it with the district office. Each district named here, with its NCES district ID, website and phone:
- Peoria Unified School District NCES ID 0406250 peoriaunified.org (623) 486-6000
- Glendale Elementary District NCES ID 0403420 gesd40.org (623) 237-7100
- Glendale Union High School District NCES ID 0403450 guhsdaz.org (623) 435-6000
The set of names changes in both directions
Glendale Union High is named for high school here and for no elementary grades, and Glendale Elementary runs 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 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: 578 of the 23,455 homes counted in 85345 sit outside the district holding the most of them, and the line between the two runs along streets rather than around the postal area.
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.
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.
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.
