DeKalb County School District

Georgia · runs pre-K through grade 12

DeKalb County covers 294,463 of the homes in 37 ZIP Code areas, but its smallest measured presence is a different thing entirely: in ZIP Code area 30350 it holds 109 of 18,405 homes, or 0.6% of them. An address in that ZIP Code is almost certainly not in this district, and a lookup that names the district without the share says the opposite. Below the half-percent line this page draws it reaches 2 further ZIP Code areas, the least of them no homes at all in 30071.

A few homes at the edge of someone else's ZIP Code

At 1,159 homes to the square mile this is city territory, and district lines in a city follow streets. DeKalb County covers 254 square miles in all — small enough that a single ZIP Code area can hold most of it, and several ZIP Codes can cut across it.

The ZIP Code areas it reaches

The spread is the thing to notice. In 30083 this district holds 100% of the homes; in 30071 it holds no homes at all. 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

DeKalb County is the largest district in 23 ZIP Code areas. Answer with its name alone and the answer misses 27,655 of the 300,689 homes those areas hold — though in 12 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

DeKalb County is the largest name in ZIP Code 30294 · Forest Park, Georgia and still holds a minority of it: 6,774 of 15,395 homes. The other 8,621 homes are 8,573 with Clayton County and Henry County; 48 in a district too small to name here. This is the shape that makes a one-name answer worst — the name is right for fewer homes than it is wrong for.

ZIP Code 30084 · Tucker, Georgia is a two-district area: 11,527 of its 16,572 homes are inside DeKalb County, and the other 5,045 homes are with Gwinnett County. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 30087 · Tucker, Georgia the split runs 9,653 to 4,627 and the larger part is DeKalb County's: the rest is 4,627 homes with Gwinnett County.

DeKalb County holds 18,241 of the 21,556 homes in ZIP Code 30319 · Brookhaven, Georgia, so its name is right for most of the area and wrong for the rest: 3,315 homes with Atlanta City and Fulton County.

In ZIP Code 30360 · Dunwoody, Georgia the split runs 5,241 to 909 and the larger part is DeKalb County's: the rest is 892 homes with Gwinnett County and 17 homes in a district too small to name here.

ZIP Code 30316 · Atlanta, Georgia is close to being two districts in equal parts: DeKalb County holds 8,228 of its 16,948 homes and Atlanta City leads the rest. A lookup that picks the larger name is making a coin-toss look like a fact.

DeKalb County reaches into ZIP Code 30030 · Decatur, Georgia with 3,900 of its 15,261 homes, behind Decatur City. The familiar answer for that area is the other name, and it is wrong for those 3,900 homes.

ZIP Code 30324 · Atlanta, Georgia is another area where DeKalb County is present without being the answer: 2,702 of its 19,029 homes, behind Atlanta City.

Who takes the other homes in its ZIP Codes

DeKalb 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 — Atlanta City, Gwinnett County and Rockdale County. They are neighbors on the same postal ground, not the next stop for its own students.

Who it shares ZIP Codes with

DeKalb County shares ZIP Code areas with 8 different districts. The most frequent are Atlanta City, Gwinnett County, Fulton County and Rockdale County. In a neighborhood this crowded the question is not which district serves the ZIP Code but which side of which street an address is on.

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 21 of the 37 ZIP Code areas DeKalb 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.
