Kenmore-Tonawanda Union Free School District

Where this district is the answer, and where it is not

At 1,862 homes to the square mile this is city territory, and district lines in a city follow streets. Kenmore-Tonawanda Union Free covers 17 square miles in all — small enough that a single ZIP Code area can hold most of it, and several ZIP Codes can cut across it.

The ZIP Code areas it reaches

The spread is the thing to notice. In 14217 this district holds 100% of the homes; in 14207 it holds 4.3% of the homes. Same district, opposite answers, and a lookup that names it without the share tells the second household the same thing as the first.

The areas it leads without holding most of the homes

Kenmore-Tonawanda Union Free is the largest name in ZIP Code 14150 · Tonawanda Town, New York and still holds a minority of it: 9,473 of 19,945 homes. The other 10,472 homes are with Tonawanda City and Sweet Home Central. This is the shape that makes a one-name answer worst — the name is right for fewer homes than it is wrong for.

ZIP Code 14223 · Tonawanda Town, New York is a two-district area: 10,449 of its 10,460 homes are inside Kenmore-Tonawanda Union Free, and the other 11 homes are in a district too small to name here. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 14217 · Tonawanda Town, New York the single-name answer is the true one: Kenmore-Tonawanda Union Free holds all 11,451 homes counted there, and no other district holds a share worth naming.

Kenmore-Tonawanda Union Free is not the name anyone would give for ZIP Code 14207 · Buffalo, New York — Buffalo City leads it — and Kenmore-Tonawanda Union Free holds 495 homes there all the same. Answer that area with one name and that is what it is wrong about.

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 2 of the 4 ZIP Code areas Kenmore-Tonawanda Union Free 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.
