The most divided ZIP Code area in Delaware

ZIP Code area 19802 holds 11,427 homes, and 4 districts each take a meaningful share of them for elementary grades — Brandywine first at 55%, then Red Clay Consolidated. A lookup that names the first is describing that share of the homes and silently not the 5,125 homes that remain.

Grade schoolBrandywine School District55%6,302 of 11,427 homes

High schoolBrandywine School District55%6,302 of 11,427 homes

Each percentage here is a share of the 11,427 homes counted in ZIP Code 19802, 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 11,427 homes counted in ZIP Code 19802, so one cell is 326 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.

Colonial School District387 of 11,427 homes3.4%

How much of Delaware a single district name misses

In 31 of those areas the largest district for the early grades holds every home counted; in the other 37 it leaves some out. That is a different count from the 34 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: 34 of the 68 ZIP Code areas in Delaware 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.
