School districts in Missouri
In Missouri the federal boundary file names an elementary district and no secondary district at all for part of 140 ZIP Code areas. That is an arrangement rather than a hole in the data: the town runs its own grade school and pays tuition for its high school students elsewhere. St. Louis City is the largest district in the state at 173,479 homes; the smallest arrangements are the ones a single-name lookup cannot describe. Its most divided ZIP Code area, 65775, is split between 10 districts for elementary grades alone. In 156 of them the answer for grade school is not the answer for high school.
How many school districts are in Missouri?

The most divided ZIP Code area in Missouri
ZIP Code area 65775 is the most divided in Missouri: 10 districts reach into its 11,101 homes, led for the early grades by West Plains R-VII and Fairview R-XI. No single name describes this postal code, and no lookup that gives one is telling the whole truth about it.
5,102 of the 11,101 homes here have no high school district named in the federal file.
Each percentage here is a share of the 11,101 homes counted in ZIP Code 65775, not the chance that any one address is in that district. Enrollment follows the street: two houses on opposite sides of the same road can be in different districts, and only the district office can say which.
Every track below is 35 cells long and stands for all 11,101 homes counted in ZIP Code 65775, so one cell is 317 homes, rounded to the nearest whole cell. Cells lit solid are the homes one district holds, and the unlit cells are the homes held by the other districts in the same list.
- West Plains R-VII School District5,720 of 11,101 homes52%
- Fairview R-XI School District1,611 of 11,101 homes15%
- Richards R-V School District1,178 of 11,101 homes11%
- Glenwood R-VIII School District1,006 of 11,101 homes9.1%
- Howell Valley R-I School District855 of 11,101 homes7.7%
- Junction Hill C-12 School District452 of 11,101 homes4.1%
- Oregon-Howell R-III School District120 of 11,101 homes1.1%
- Alton R-IV School District60 of 11,101 homes0.5%
3 further districts reach into this area and hold 99 homes between them, under half a percent of the homes named at this level each.
For grade school, an answer of one district name would be wrong for 5,381 of the 11,101 here.
Where the high school answer in Missouri is missing from the file
Across the 1,034 ZIP Code areas in Missouri with homes in them, an answer of one district name misses 376,961 of the 2,786,952 homes they hold. The arithmetic understates it here: in 140 of those areas some homes have no high school district named at all, so the name that is right for the early grades is not wrong later — there is nothing there to be right about.
ZIP Code 63123 · Affton, Missouri names 5 districts. Affton 101 is the largest of them for grade school, and an answer of its name alone misses 12,912 of the 23,854 homes there; for grade school the rest is 12,912 homes with Bayless, Lindbergh, Mehlville R-IX and one more district.
In ZIP Code 63376 · St. Peters, Missouri the largest district for grade school is Fort Zumwalt R-II, and naming it alone misses 12,781 of the 30,463 homes counted there. For grade school the rest is 12,781 homes with Francis Howell R-III and St. Charles R-VI.
ZIP Code 63136 · Jennings, Missouri names 4 districts. Riverview Gardens is the largest of them for grade school, and an answer of its name alone misses 11,763 of the 20,674 homes there; for grade school the rest is 11,741 homes with Jennings, Hazelwood and St. Louis City; 22 homes in districts too small to name here.
Where a ZIP Code here names more than one district
Of the 1,034 ZIP Code areas in Missouri that the federal file names a district for, 749 name more than one school district.

Each row opens the full answer for that ZIP Code, with every district named for grade school and for high school and the share of the homes each one holds.

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: 749 of the 1,034 ZIP Code areas in Missouri with a district named for them are served by more than one school district, and the line between two of 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.
