The areas it leads without holding most of the homes

Peoria Unified is the largest district in 8 ZIP Code areas. Answer with its name alone and the answer misses 20,989 of the 112,091 homes those areas hold — though in 2 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

Peoria Unified holds 17,787 of the 25,243 homes in ZIP Code 85383 · Peoria, Arizona, so its name is right for most of the area and wrong for the rest: 7,437 homes with Deer Valley Unified and 19 homes in a district too small to name here.

Peoria Unified holds 4,575 of the 10,853 homes in ZIP Code 85373 · Sun City, Arizona, and 6,253 of the homes counted there have no high school district named for them in the federal file at all. A lookup that answers with one name misses 6,278 of them, and it also misses the arrangement: the high school districts the file does name here are Peoria Unified and Dysart Unified.

ZIP Code 85306 · Glendale, Arizona is a two-district area: 6,715 of its 9,776 homes are inside Peoria Unified, and the other 3,061 homes are with Washington Elementary. Which one an address belongs to is settled by the street, not by the five digits.

They are neighbors on the same postal ground, not the next stop for its own students.

Who it shares ZIP Codes with

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 11 of the 17 ZIP Code areas Peoria Unified 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.
