The ZIP Code areas it reaches

The spread is the thing to notice. In 29485 this district holds 92% of the homes; in 29414 it holds 21 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.

The areas it leads without holding most of the homes

Dorchester School District 2 is the largest district in 5 ZIP Code areas, and not one of them is wholly its own. Answer with its name alone and the answer misses 18,444 of the 73,772 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.

Dorchester School District 2 is the largest name in ZIP Code 29456 · North Charleston, South Carolina and still holds a minority of it: 6,291 of 15,367 homes. The other 9,076 homes are with Charleston County and Berkeley County. This is the shape that makes a one-name answer worst — the name is right for fewer homes than it is wrong for.

Dorchester School District 2 holds 19,964 of the 22,812 homes in ZIP Code 29483 · Summerville, South Carolina, so its name is right for most of the area and wrong for the rest: 2,848 homes with Berkeley County and Charleston County.

ZIP Code 29420 · North Charleston, South Carolina is a two-district area: 6,742 of its 9,100 homes are inside Dorchester School District 2, and the other 2,358 homes are with Charleston County. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 29485 · North Charleston, South Carolina the split runs 21,017 to 1,790 and the larger part is Dorchester School District 2's: the rest is 1,790 homes with Charleston County.

Dorchester School District 2 reaches into ZIP Code 29418 · North Charleston, South Carolina with 2,472 of its 10,947 homes, behind Charleston County. The familiar answer for that area is the other name, and it is wrong for those 2,472 homes.

Dorchester School District 2 is not the name anyone would give for ZIP Code 29470 · Ravenel, South Carolina — Charleston County leads it — and Dorchester School District 2 holds 154 homes there all the same. Answer that area with one name and that is what it is wrong about.

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 8 of the 9 ZIP Code areas Dorchester School District 2 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.
