School districts in Oklahoma
In Oklahoma the federal boundary file names an elementary district and no secondary district at all for part of 124 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. Oklahoma City is the largest district in the state at 136,908 homes; the smallest arrangements are the ones a single-name lookup cannot describe. Its most divided ZIP Code area, 74501, is split between 12 districts for elementary grades alone. In 128 of them the answer for grade school is not the answer for high school.
Towns that run grade school and buy the rest
The state sits well above the national rate: 73% of its ZIP Code areas cross a district line against 53% across the country. With 506 districts over 663 populated ZIP Code areas, every extra district is another line to cross.

The most divided ZIP Code area in Oklahoma
ZIP Code area 74501 holds 12,841 homes and 12 districts take a real share of them for the early grades, but McAlester holds 61% on its own at that level. This is the shape that makes a single-name lookup look right: it names McAlester and describes most of the homes here, and silently not the rest.
2,169 of the 12,841 homes here have no high school district named in the federal file.
Each percentage here is a share of the 12,841 homes counted in ZIP Code 74501, 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 12,841 homes counted in ZIP Code 74501, so one cell is 367 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.

- Stuart Public Schools118 of 12,841 homes0.9%
- Hartshorne Public Schools96 of 12,841 homes0.7%
2 further districts reach into this area and hold 30 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 5,064 of the 12,841 here.
Where the high school answer in Oklahoma is missing from the file
Across the 663 ZIP Code areas in Oklahoma with homes in them, an answer of one district name misses 299,590 of the 1,746,757 homes they hold. The arithmetic understates it here: in 124 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 73099 · Oklahoma City, Oklahoma names 4 districts. Yukon is the largest of them for grade school, and an answer of its name alone misses 14,458 of the 33,316 homes there; Mustang, Piedmont and Banner Public School hold the rest.
In ZIP Code 74136 · Tulsa, Oklahoma the largest district for grade school is Tulsa, and naming it alone misses 7,671 of the 16,241 homes counted there. The rest are with Jenks and Union.
ZIP Code 73401 · Ardmore, Oklahoma names 5 districts. Ardmore is the largest of them for grade school, and an answer of its name alone misses 7,526 of the 16,442 homes there; Plainview, Dickson and Lone Grove hold the rest.
Where a ZIP Code here names more than one district
Of the 663 ZIP Code areas in Oklahoma that the federal file names a district for, 485 name more than one school district. These are the 12 with the most, starting at 12 districts in one postal area: McAlester, Park Hill and Rocky Mountain. 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. 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: 485 of the 663 ZIP Code areas in Oklahoma 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.
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.
