Where no high school district is named

In 768 ZIP Code areas the federal file names an elementary district and leaves more than 2% of the homes counted there with no high school district named. That is not missing data: it is an arrangement in which a town runs its own grade school and buys high school places from somebody else. Of the 60 areas listed below, 33 are in New Hampshire (15), Arizona (11) and Maine (7), which is where the arrangement is concentrated.

Which of these have a page here

1 of the 60 areas listed above have a page of their own on this site, each with the full split by grade band, the districts that reach into it and how it compares inside its state. The other 59 are answered by the lookup, which holds every one of the 33,559 ZIP Code areas in the country with homes in them and needs no page to do it. A page is added where the set of districts is unique in the country and the two grade bands have something to disagree about; everywhere else a page would only repeat what the lookup already computes.

Where the arrangement lives

Counted over all 768 areas rather than the 60 shown, 320 are in the six New England states, where a town has run its own school since before the state did and buys high school places from a neighbor or an academy. The rest are spread through the rural West and Midwest, where distance rather than history produced the same arrangement.

The largest single case is ZIP Code 85614 · Green Valley, Arizona: 15,499 of its homes have no secondary district named in the federal file at all. That is not a small print exception to a lookup answer — it is the whole answer for high school, and no national dataset contains it. The town office is the only place that knows which school the students are sent to, and whether the family chooses.

What to do with this

If your ZIP Code is on this list, the question “which district” has no answer for high school, and the right question for the town office is where its students are sent and whether the family gets a choice. Some towns designate one receiving school; some let families choose among several; a few send students to a private academy that serves as the town high school.

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: 17,865 of the 33,555 ZIP Code areas in the country with homes in them are served by more than one school district, and the line between two of 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.
