ZIP Code 85033 · Phoenix, Arizona
Maricopa County · 16,168 counted · 4 districts
Each percentage here is a share of the 16,168 homes counted in ZIP Code 85033, 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 85033, Phoenix, Arizona are not the districts named for high school, and the set changes in both directions: 2 districts arrive for high school that no elementary answer names, and 2 run the early grades and stop. 4 districts hold the 16,168 homes counted here between them, and Cartwright Elementary and Phoenix Union High hold the most of them, 15,857 homes each. The largest share is high enough that one name is right for most of the homes counted and wrong for the other 311: 311 homes with Pendergast 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.

Then confirm it with the district office. Each district named here, with its NCES district ID, website and phone:
- Cartwright Elementary District NCES ID 0401680 csd83.org (623) 691-4000
- Phoenix Union High School District NCES ID 0406330 phoenixunion.org (602) 764-0860
- Pendergast Elementary District NCES ID 0406210 pesd92.org (623) 772-2200
- Tolleson Union High School District NCES ID 0408520 tuhsd.org (623) 478-4000
The set of names changes in both directions
Phoenix Union High and Tolleson Union High are named for high school here and for no elementary grades, and Cartwright Elementary and Pendergast Elementary run 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: 311 of the 16,168 homes counted in 85033 sit outside each of the 2 districts tied for the most of them, and the line 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.
