ZIP Code 60453 · Oak Lawn, Illinois
Cook County · 23,362 counted · 7 districts
Each percentage here is a share of the 23,362 homes counted in ZIP Code 60453, 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.
The districts named for the early grades in ZIP Code 60453, Oak Lawn, Illinois are not the districts named for high school, and the set changes in both directions: one district arrives for high school that no elementary answer names, and another runs the early grades and stops. 7 districts hold the 23,362 homes counted here between them, and Oak Lawn-Hometown School District 123 is the largest by homes. The largest share leaves 10,389 homes elsewhere: 10,389 homes with Ridgeland School District 122, Alsip-Hazelgreen-Oaklawn School District 126, Chicago Ridge School District 127-5 and 1 more district.

Oak Lawn Community High School District 229 and Community High School District 218 are named here for high school and not for the early grades.
- Oak Lawn Community High School District 22912,638 of 23,362 homes54%
- Community High School District 21810,724 of 23,362 homes46%
The set of names changes in both directions
Community High School District 218 and Oak Lawn Community High School District 229 are named for high school here and for no elementary grades, and Alsip-Hazelgreen-Oaklawn School District 126, Atwood Heights School District 125 and Chicago Ridge School District 127-5 run the early grades and no more. An address on the wrong street can therefore change district at the change of grade and land in a district that was never part of its elementary answer, while a neighbor two blocks away keeps one name the whole way through.
What one district name costs in 60453
A lookup that answers ZIP Code 60453 with one district name has to pick one of the names below and drop the rest.

That is the whole difference between this page and a one-line answer: the same federal file, read to the end instead of to the first row.

Nothing here is fetched from anywhere while you read: the whole index travels with the lookup page itself.
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: 10,389 of the 23,362 homes counted in 60453 sit outside the district holding the most of them, and the line between the two runs along streets rather than around the postal area.
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.
What this site can hand you instead:
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.
