Seaford School District
Delaware · runs pre-K through grade 12
NCES ID 1001530 · seafordbluejays.org · (302) 629-4587
There is no ZIP Code area where Seaford is the only school district serving the homes. It holds a real share in 3 of them and shares every one, with 4 different districts in total. A lookup that returns a single district name for any of those ZIP Codes is guessing which side of a line an address falls on.
It never has a ZIP Code to itself
By homes covered Seaford sits in the bottom quarter of the 16 districts in Delaware, and that is the interesting part: a small district still shows up in 4 ZIP Code areas, because a ZIP Code area does not shrink to fit.

The ZIP Code areas it reaches
The spread is the thing to notice. In 19973 this district holds 95% of the homes; in 19947 it holds 23 homes, under half a percent. Same district, opposite answers, and a lookup that names it without the share tells the second household the same thing as the first.

- ZIP Code 19933 · Bridgeville, Delaware6.1% of the homes
- ZIP Code 19956 · Laurel, Delaware1.4% of the homes
- ZIP Code 19947 · Georgetown, Delaware23 homes, under half a percent
What one name misses in the areas it leads
Seaford is the largest district in 1 ZIP Code area, and that area is not wholly its own. Answer with its name alone and the answer misses 552 of the 10,547 homes that area holds. That count is computed here from census blocks; the lookups that answer this question with a single name never print it.
Seaford is one of 5 districts the file names for ZIP Code 19973 · Seaford, Delaware at that level. It holds 9,995 of the 10,547 homes there; the rest is 522 homes with Laurel, Dorchester County and Woodbridge; 30 homes in a district too small to name here. One name for that area is not a simplification, it is a different answer for 552 of the homes in it.
Seaford is not the name anyone would give for ZIP Code 19933 · Bridgeville, Delaware — Woodbridge leads it — and Seaford holds 248 homes there all the same. Answer that area with one name and that is what it is wrong about.
ZIP Code 19956 · Laurel, Delaware is another area where Seaford is present without being the answer: 92 of its 6,508 homes, behind Laurel.
Who takes the other homes in its ZIP Codes
Seaford runs pre-K through grade 12 itself, so an address it holds sees no change of authority between grade school and high school.

They are neighbors on the same postal ground, not the next stop for its own students.

Have a street address?
A ZIP Code names every district that can serve the area; a street address settles which one serves a home. The Census Bureau geocoder takes an exact address and returns its school districts from the current boundary files, free and with no account.
Where this district sits
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 3 of the 4 ZIP Code areas Seaford 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.
