Each percentage here is a share of the 16,114 homes counted in ZIP Code 85042, 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 85042, 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 3 run the early grades and stop. 5 districts hold the 16,114 homes counted here between them, and Phoenix Union High and Roosevelt Elementary hold the most of them, 12,406 homes each. The largest share leaves 3,708 homes elsewhere: 3,708 homes with Tempe School District and Kyrene Elementary. The area sits in Maricopa County, Arizona.

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:

  • Phoenix Union High School District NCES ID 0406330 phoenixunion.org (602) 764-0860
  • Roosevelt Elementary District NCES ID 0407080 rsd66.org (602) 243-4800
  • Tempe Union High School District NCES ID 0408340 tempeunion.org (480) 839-0292
  • Tempe School District NCES ID 0408310 tempeschools.org (480) 730-7100
  • Kyrene Elementary District NCES ID 0404230 kyrene.org (480) 541-1000

The set of names changes in both directions

Phoenix Union High and Tempe Union High are named for high school here and for no elementary grades, and Roosevelt Elementary, Tempe School District and Kyrene 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 one district name costs in 85042

A lookup that answers ZIP Code 85042 with one district name has to pick one of the names below and drop the rest. Measured against the 16,114 homes counted here, for the early grades it is wrong for 3,708 homes and for high school it is wrong for 3,708 homes. That is the whole difference between this page and a one-line answer: the same federal file, read to the end instead of to the first row.

Look up 85042 again, or look up another ZIP Code

The lookup holds every ZIP Code area in the country with homes in it, including the ones with no page of their own. Opening it at 85042 recomputes the same 16,114 homes from the same snapshot, and typing five other digits answers for somewhere else. No server is asked for the answer: the whole index travels with the lookup page itself.

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: 3,708 of the 16,114 homes counted in 85042 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.
