ZIP Code 60030 · Grayslake, Illinois
Lake County · 15,104 counted · 6 districts
Each percentage here is a share of the 15,104 homes counted in ZIP Code 60030, 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 60030, Grayslake, Illinois are not the districts named for high school, and the set changes in both directions: 3 districts arrive for high school that no elementary answer names, and 3 run the early grades and stop. 6 districts hold the 15,104 homes counted here between them, and Grayslake Community High School District 127 is the largest by homes. The largest share leaves 4,973 homes elsewhere: 4,908 homes with Warren Township High School District 121 and Mundelein Consolidated High School District 120; 65 homes in districts too small to name here.
Three districts share the early grades
3 districts hold a measurable share of ZIP Code 60030 at this level. Grayslake Consolidated Community School District 46 is the largest with 8,213 homes; the smallest of them holds 1,884 homes. Grayslake Consolidated Community School District 46, Woodland Community Consolidated School District 50 and Fremont School District 79 are named here for grade school and not for high school.
Every track below is 35 cells long and stands for all 15,104 homes counted in ZIP Code 60030, so one cell is 432 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.

Below half a percent at the grade school level: Libertyville School District 70 and Wauconda Community Unit School District 118 hold 65 homes between them, which is why they are counted under the list rather than inside it. A lookup that named them alongside the districts above would be listing a boundary crossing rather than an answer.
Round Lake Community Unit School District 116 reaches into ZIP Code 60030 at the grade school level as well and holds no home counted in it: the boundary crosses the postal area without picking up a single one.

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.

The set of names changes in both directions
Grayslake Community High School District 127, Warren Township High School District 121 and Mundelein Consolidated High School District 120 are named for high school here and for no elementary grades, and Grayslake Consolidated Community School District 46, Woodland Community Consolidated School District 50 and Fremont School District 79 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 60030
A lookup that answers ZIP Code 60030 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.

Look up 60030 again, or look up another ZIP Code
The lookup holds every ZIP Code area in the country with homes in it, including the ones with no page of their own. Opening it at 60030 recomputes the same 15,104 homes from the same snapshot, and typing five other digits answers for somewhere else. No server is asked for the answer: the whole index travels with the lookup page itself.
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: 4,973 of the 15,104 homes counted in 60030 sit outside the district holding the most of them, and the line between the two runs along streets rather than around the postal area.
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.
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.
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.
