Edgefield County School District

It never has a ZIP Code to itself

The counts below come from the census blocks assigned to Edgefield County, 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 29824 this district holds 99% of the homes; in 29138 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.

What one name misses in the areas it leads

Edgefield County 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 4,301 of the 14,623 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.

ZIP Code 29860 · North Augusta, South Carolina is a two-district area: 3,765 of its 7,174 homes are inside Edgefield County, and the other 3,409 homes are with Aiken County. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 29847 · Trenton, South Carolina the split runs 1,651 to 485 and the larger part is Edgefield County's: the rest is 485 homes with Aiken County.

Edgefield County holds 1,921 of the 2,312 homes in ZIP Code 29832 · Johnston, South Carolina, so its name is right for most of the area and wrong for the rest: 391 homes with Saluda County and Aiken County.

ZIP Code 29821 · Clarks Hill, South Carolina is close to being two districts in equal parts: Edgefield County holds 292 of its 668 homes and McCormick County leads the rest. A lookup that picks the larger name is making a coin-toss look like a fact.

Edgefield County reaches into ZIP Code 29838 · Modoc, South Carolina with 127 of its 404 homes, behind McCormick County. The familiar answer for that area is the other name, and it is wrong for those 127 homes.

Edgefield County is not the name anyone would give for ZIP Code 29835 · Willington, South Carolina — McCormick County leads it — and Edgefield County holds 119 homes there all the same. Answer that area with one name and that is what it is wrong about.

ZIP Code 29129 · Ridge Spring, South Carolina is another area where Edgefield County is present without being the answer: 86 of its 1,357 homes, behind Aiken County.

Who takes the other homes in its ZIP Codes

Edgefield County 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 — Aiken County, McCormick County and Saluda County. They are neighbors on the same postal ground, not the next stop for its own students.

• Aiken County School District5,304 homes in 4 shared ZIP Code areas
• McCormick County School District5,014 homes in 4 shared ZIP Code areas
• Saluda County School District4,661 homes in 3 shared ZIP Code areas

Who it shares ZIP Codes with

These districts appear alongside Edgefield County in the same ZIP Code areas: Aiken County, McCormick County, Saluda County and Lexington School District 3. 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.

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 9 of the 10 ZIP Code areas Edgefield County 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.
