Below half a percent at the grade school level: Downers Grove Grade School District 58 holds 20 homes, which is why it is counted under the list rather than inside it. A lookup that named it alongside the districts above would be listing a boundary crossing rather than an answer.

High school is split between two districts

2 districts hold a measurable share of ZIP Code 60148 at this level. Glenbard Township High School District 87 is the largest with 16,927 homes; the smallest of them holds 5,256 homes. Glenbard Township High School District 87 and DuPage High School District 88 are named here for high school and not for the early grades.

• Glenbard Township High School District 8716,927 of 22,203 homes76%
• DuPage High School District 885,256 of 22,203 homes24%

Below half a percent at the high school level: Community High School District 99 holds 20 homes, which is why it is counted under the list rather than inside it. A lookup that named it alongside the districts above would be listing a boundary crossing rather than an answer.

The set of names changes in both directions

DuPage High School District 88 and Glenbard Township High School District 87 are named for high school here and for no elementary grades, and Addison School District 4, Glen Ellyn School District 41 and Lombard School District 44 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 60148

A lookup that answers ZIP Code 60148 with one district name has to pick one of the names below and drop the rest. Measured against the 22,203 homes counted here, for the early grades it is wrong for 7,782 homes and for high school it is wrong for 5,276 homes. 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.

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: 5,276 of the 22,203 homes counted in 60148 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:

• Glenbard Township High School District 8711 ZIP Code areas in all
• How this is worked out4 Census Bureau files

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.
