What one name misses where high school is arranged elsewhere

Dysart Unified is the largest district in 9 ZIP Code areas. Answer with its name alone and the answer misses 19,580 of the 95,982 homes those areas hold — though in 4 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

Dysart Unified holds 3,652 of the 19,718 homes in ZIP Code 85375 · Sun City West, Arizona, and 13,907 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 16,066 of them, and it also misses the arrangement: the high school districts the file does name here are Dysart Unified and Peoria Unified.

Dysart Unified holds 5,531 of the 7,487 homes in ZIP Code 85387 · Surprise, Arizona, so its name is right for most of the area and wrong for the rest: 1,500 homes with Nadaburg Unified and Wickenburg Unified; 456 homes in no grade school district in the federal file.

ZIP Code 85355 · Citrus Park, Arizona is a two-district area: 3,126 of its 4,204 homes are inside Dysart Unified, and the other 1,078 homes are with Litchfield Elementary. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 85378 · Surprise, Arizona the split runs 3,631 to 476 and the larger part is Dysart Unified's: the rest is 476 homes with Peoria Unified.

In ZIP Code 85335 · El Mirage, Arizona the single-name answer is the true one: Dysart Unified holds all 11,482 homes counted there, and no other district holds a share worth naming.

Dysart Unified reaches into ZIP Code 85363 · Youngtown, Arizona with 780 of its 2,724 homes, behind Peoria Unified. The familiar answer for that area is the other name, and it is wrong for those 780 homes.

In ZIP Code 85307 · Glendale, Arizona this district is one name among 6. Agua Fria Union High leads with the largest share and Dysart Unified holds 722 of the 3,953 homes counted there; no single name describes that area at all.

Dysart Unified is not the name anyone would give for ZIP Code 85361 · Surprise, Arizona — Nadaburg Unified leads it — and Dysart Unified holds 31 homes there all the same. Answer that area with one name and that is what it is wrong about.

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 8 of the 15 ZIP Code areas Dysart 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.
