The ZIP Code areas it reaches

The spread is the thing to notice. In 40214 this district holds 100% of the homes; in 40231 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.

What an answer of one district name misses here

Jefferson County School District is the largest district in 38 ZIP Code areas. Answer with its name alone and the answer misses 10,906 of the 366,849 homes those areas hold — though in 30 of them it holds every home there is.

ZIP Code 40229 · Louisville/Jefferson County, Kentucky is a two-district area: 10,605 of its 15,827 homes are inside Jefferson County School District, and the other 5,222 homes are with Bullitt County. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 40245 · Louisville/Jefferson County, Kentucky the split runs 14,085 to 660 and the larger part is Jefferson County School District's: the rest is 647 homes with Shelby County and 13 homes in a district too small to name here.

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 8 of the 43 ZIP Code areas Jefferson County School District 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.
