Each percentage here is a share of the 20,609 homes counted in ZIP Code 53209, 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.

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:

The set of names changes in both directions

Nicolet Union High is named for high school here and for no elementary grades, and Glendale-River Hills 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 one district name costs in 53209

A lookup that answers ZIP Code 53209 with one district name has to pick one of the names below and drop the rest. Measured against the 20,609 homes counted here, for the early grades it is wrong for 5,699 homes and for high school it is wrong for 5,699 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 53209 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.

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: 5,699 of the 20,609 homes counted in 53209 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.
