The ZIP Code areas it reaches

The spread is the thing to notice. In 07851 this district holds 100% of the homes; in 07825 it holds 2.0% of the homes. Same district, opposite answers, and a lookup that names it without the share tells the second household the same thing as the first.

The areas it leads without holding most of the homes

Kittatinny Regional is the largest district in 3 ZIP Code areas. Answer with its name alone and the answer misses 6,088 of the 11,297 homes those areas hold — though in 2 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

Kittatinny Regional is the largest name in ZIP Code 07860 · Newton, New Jersey and still holds a minority of it: 5,092 of 11,180 homes. The other 6,088 homes are with Newton Town, Andover Regional, High Point Regional and 2 more districts. This is the shape that makes a one-name answer worst — the name is right for fewer homes than it is wrong for.

In ZIP Code 07851 · Layton, New Jersey the single-name answer is the true one: Kittatinny Regional holds all 112 homes counted there, and no other district holds a share worth naming.

ZIP Code 07881 · Walpack, New Jersey is another area where one name covers everything — 5 homes, all of them inside Kittatinny Regional.

In ZIP Code 07826 · Layton, New Jersey this district is one name among 5. High Point Regional leads with the largest share and Kittatinny Regional holds 688 of the 2,806 homes counted there; no single name describes that area at all.

ZIP Code 07848 · Ross Corner, New Jersey repeats the pattern with 6 names holding a real share: 218 of its 1,779 homes are Kittatinny Regional's, and the other 1,561 are not.

Kittatinny Regional is not the name anyone would give for ZIP Code 07827 · Layton, New Jersey — Montague Township leads it — and Kittatinny Regional holds 179 homes there all the same. Answer that area with one name and that is what it is wrong about.

ZIP Code 07825 · Marksboro, New Jersey is another area where Kittatinny Regional is present without being the answer: 75 of its 3,724 homes, behind North Warren Regional.

The elementary districts that feed it

Students arrive at Kittatinny Regional from 6 districts that run the lower grades on the same ground — Newton Town, which sends 26%, Hampton Township, which sends 14% and Stillwater Township, which sends 13%. Each of those addresses therefore belongs to two districts at once, one for grade school and this one for high school, and neither name is the whole answer.

• Newton Town School District26% of Kittatinny Regional's homes come from here
• Hampton Township School District14% of Kittatinny Regional's homes come from here
• Stillwater Township School District13% of Kittatinny Regional's homes come from here
• Frankford Township School District11% of Kittatinny Regional's homes come from here
• Andover Regional School District11% of Kittatinny Regional's homes come from here
• Fredon Township School District9.0% of Kittatinny Regional's homes come from here

The names in this list are exact: the federal file gives the district of each band for every census block. The percentages are not. They spread each shared ZIP Code area's homes across the other band in proportion to the share each district holds there, because the file names the two districts of a block and not how a household moves between them. Read them as the size of the crossing, not as a count of houses.

Who it shares ZIP Codes with

Kittatinny Regional shares ZIP Code areas with 17 different districts. The most frequent are Sandyston-Walpack Township, Frankford Township, High Point Regional and Andover Regional.

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 7 of the 7 ZIP Code areas Kittatinny Regional 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.
