The ZIP Code areas it reaches

The spread is the thing to notice. In 30080 this district holds 100% of the homes; in 30122 it holds 1 home, 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 an answer of one district name misses here

Cobb County is the largest district in 18 ZIP Code areas. Answer with its name alone and the answer misses 38,258 of the 309,087 homes those areas hold — though in 5 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

ZIP Code 30064 · Marietta, Georgia is a two-district area: 12,772 of its 19,547 homes are inside Cobb County, and the other 6,775 homes are with Marietta City. Which one an address belongs to is settled by the street, not by the five digits.

Cobb County holds 15,565 of the 22,179 homes in ZIP Code 30067 · Marietta, Georgia, so its name is right for most of the area and wrong for the rest: 6,614 homes with Marietta City.

In ZIP Code 30060 · Marietta, Georgia the split runs 9,406 to 5,590 and the larger part is Cobb County's: the rest is 5,590 homes with Marietta City.

In ZIP Code 30101 · Acworth, Georgia the split runs 17,580 to 4,946 and the larger part is Cobb County's: the rest is 4,849 homes with Paulding County and Bartow County; 97 homes in districts too small to name here.

In ZIP Code 30080 · Smyrna, Georgia the single-name answer is the true one: Cobb County holds all 25,989 homes counted there, and no other district holds a share worth naming.

Cobb County reaches into ZIP Code 30102 · Cherokee County, Georgia with 4,349 of its 15,867 homes; 3 districts there hold a real share of it, and Cherokee County leads them. The familiar answer for that area is one of the others, and it is wrong for those 4,349 homes.

ZIP Code 30075 · Roswell, Georgia is another area where Cobb County is present without being the answer: 3,714 of its 21,652 homes, behind Fulton County.

Cobb County is not the name anyone would give for ZIP Code 30188 · Woodstock, Georgia — Cherokee County leads it — and Cobb County holds 495 homes there all the same. Answer that area with one name and that is what it is wrong about.

Who takes the other homes in its ZIP Codes

They are neighbors on the same postal ground, not the next stop for its own students.

Have a street address?

A ZIP Code names every district that can serve the area; a street address settles which one serves a home. The Census Bureau geocoder takes an exact address and returns its school districts from the current boundary files, free and with no account.

What to do next

Ask the district office to confirm your street address: look on its site for a school locator, a find my school tool or an attendance zone map, or call the office.

A ZIP Code is a set of mail delivery routes, not a boundary: in 17 of the 24 ZIP Code areas Cobb 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.

District websites and phone numbers here come from the NCES Common Core of Data directory, 2024-25 school year, filed under the same district ID as the Census boundary files. Where it lists no usable website, none is printed rather than guessed.

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.

Where these numbers come from

The homes were counted in the 2020 Census and the district lines are the 2026 boundary file, so a fast-growing area may have changed since; ZIP Codes here are the Census Bureau's ZIP Code Tabulation Areas; a share is a share of homes, not the chance that one address is in a district; and a district is not a school attendance zone. Every source, file and caveat is on the method page.
