The most divided ZIP Code area in New York
ZIP Code area 13021 holds 18,827 homes and 8 districts take a real share of them for the early grades, but Auburn City holds 84% on its own at that level. This is the shape that makes a single-name lookup look right: it names Auburn City and describes most of the homes here, and silently not the rest.
Each percentage here is a share of the 18,827 homes counted in ZIP Code 13021, 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.
Every track below is 35 cells long and stands for all 18,827 homes counted in ZIP Code 13021, so one cell is 538 homes, rounded to the nearest whole cell. Cells lit solid are the homes one district holds, and the unlit cells are the homes held by the other districts in the same list.

For grade school, an answer of one district name would be wrong for 3,021 of the 18,827 here.
How much of New York a single district name misses
Across the 1,807 ZIP Code areas in New York with homes in them, an answer of one district name misses 781,726 of the 8,488,023 homes they hold — 9.2% of the state. In 724 of those areas the largest district for the early grades holds every home counted; in the other 1,083 it leaves some out. That is a different count from the 1,018 areas served by more than one district: it also counts districts under half a percent of the homes and homes in no district, and it does not count a high school district that differs.

South Huntington Union Free is the largest of them for grade school, and an answer of its name alone misses 13,065 of the 22,045 homes there; for grade school the rest is 12,969 homes with Half Hollow Hills Central, Huntington Union Free and Commack Union Free; 96 homes in a district too small to name here.

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: 1,018 of the 1,807 ZIP Code areas in New York with a district named for 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.
