The most divided ZIP Code area in Pennsylvania
ZIP Code area 15946 holds 3,107 homes and 7 districts take a real share of them for the early grades, but Portage Area holds 86% on its own at that level. This is the shape that makes a single-name lookup look right: it names Portage Area and describes most of the homes here, and silently not the rest.
Each percentage here is a share of the 3,107 homes counted in ZIP Code 15946, 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 3,107 homes counted in ZIP Code 15946, so one cell is 89 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.

How much of Pennsylvania a single district name misses
Across the 1,826 ZIP Code areas in Pennsylvania with homes in them, an answer of one district name misses 893,114 of the 5,742,828 homes they hold — 16% of the state. In 892 of those areas the largest district for the early grades holds every home counted; in the other 934 it leaves some out. That is a different count from the 868 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.

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: 868 of the 1,826 ZIP Code areas in Pennsylvania 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.
