Lake Forest School District
Delaware · runs pre-K through grade 12
There is no ZIP Code area where Lake Forest is the only school district serving the homes. It holds a real share in 5 of them and shares every one, with 3 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
The counts below come from the census blocks assigned to Lake Forest, grouped by the ZIP Code area each block falls in. The Census Bureau publishes the blocks; the grouping is computed here, and it is the only place these particular numbers exist.

The ZIP Code areas it reaches
The spread is the thing to notice. In 19943 this district holds 93% of the homes; in 19950 it holds 3 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 19979 · Viola, Delaware93% of the homes
- ZIP Code 19946 · Frederica, Delaware91% of the homes

What one name misses in the areas it leads
Lake Forest is the largest district in 4 ZIP Code areas, and not one of them is wholly its own. Answer with its name alone and the answer misses 1,209 of the 12,132 homes those areas hold. That count is computed here from census blocks; the lookups that answer this question with a single name never print it.
Lake Forest holds 3,872 of the 4,498 homes in ZIP Code 19952 · Harrington, Delaware, so its name is right for most of the area and wrong for the rest: 626 homes with Woodbridge and Milford.
ZIP Code 19943 · Riverview, Delaware is a two-district area: 4,865 of its 5,239 homes are inside Lake Forest, and the other 374 homes are with Caesar Rodney. Which one an address belongs to is settled by the street, not by the five digits.
In ZIP Code 19946 · Frederica, Delaware the split runs 1,911 to 187 and the larger part is Lake Forest's: the rest is 187 homes with Milford and Caesar Rodney.
In ZIP Code 19979 · Viola, Delaware the split runs 275 to 22 and the larger part is Lake Forest's: the rest is 22 homes with Caesar Rodney.
Lake Forest reaches into ZIP Code 19954 · Houston, Delaware with 97 of its 660 homes, behind Milford. The familiar answer for that area is the other name, and it is wrong for those 97 homes.
Who takes the other homes in its ZIP Codes
Lake Forest runs pre-K through grade 12 itself, so an address it holds sees no change of authority between grade school and high school. The districts listed below are the ones that take the other homes in the ZIP Code areas it shares — Caesar Rodney, Woodbridge and Milford. They are neighbors on the same postal ground, not the next stop for its own students.
- Caesar Rodney School District10,903 homes in 5 shared ZIP Code areas
- Woodbridge School District2,698 homes in 2 shared ZIP Code areas
- Milford School District1,493 homes in 4 shared ZIP Code areas
Who it shares ZIP Codes with
These districts appear alongside Lake Forest in the same ZIP Code areas: Caesar Rodney, Milford and Woodbridge. A single-name lookup for one of those areas has to choose between them, and the choice is right for some addresses and wrong for others.

Where this district sits
What to do next
Ask the district office to confirm your street address. A district settles that question on its own site: look for a school locator, a find my school tool, or an attendance zone map. Where there is none, ask the office itself.
A ZIP Code is a set of mail delivery routes, not a boundary: in 5 of the 8 ZIP Code areas Lake Forest 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.
This site links to no district website. None of the federal files it is built from publishes one, and a guessed address is worse than none. It is the district office, not a search engine, that settles an address.
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.
What this cannot tell you
The homes were counted in the 2020 Census and the district lines are the 2026 boundary file. Nothing on this page adjusts one to the other. Where houses have been built or cleared since the count, a share here describes the place as it was counted rather than as it stands today, and in the fastest-growing ZIP Code areas that gap is the largest single source of error on this site.
A share on this page is a share of the homes in the ZIP Code area, not a probability for any particular address. Enrollment is decided by street address, and a district may run magnet, charter or choice programs that ignore the boundary entirely. If a decision depends on the answer, the district office is the only authority; this page shows what the federal boundary files say and when they were published.
A district boundary is not a school attendance zone. This site never says which school an address is assigned to: no current national dataset of attendance zones exists, and the district draws them itself. Nor is anything here endorsed or certified by the Census Bureau; we use their published files, and that is the whole of the relationship.
A ZIP Code is a set of mail delivery routes, not an area. What is mapped here is the Census Bureau's ZIP Code Tabulation Area, the closest published approximation to it. The two are not identical, and a handful of ZIP Codes used only for post office boxes or single buildings have no tabulation area at all.
Where these numbers come from
School district boundaries come from the Census Bureau's Census Geographic Relationship File, current 2026 vintage, which assigns every census block to a unified district or to an elementary and a secondary district. Homes and residents in each block come from the 2020 Census Redistricting Data (PL 94-171), H1_001 and P1_001. The ZIP Code areas come from the same Geographic Relationship File, block to ZIP Code Tabulation Area. District names and grade ranges come from the Census Gazetteer 2025, with 2020 for districts no longer listed.
The place name printed beside a ZIP Code comes from the Census 2020 ZIP Code Tabulation Area relationship files: place, county subdivision and county, taken 2026-09-06. It is a label rather than a measurement: the Census Bureau does not publish which post office a ZIP Code belongs to, so the place named is the one covering the most land inside the area, not the city the Postal Service prints on an envelope.
Everything else on this page — the shares, the counts of districts per ZIP, the comparison between the two grade bands, the rankings — is computed here from those files. The source publishes none of it. Snapshot taken 2026-09-03.
