High schoolGreat Falls High School District98%15,048 of 15,393 homes

Each percentage here is a share of the 15,393 homes counted in ZIP Code 59405, 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 59405, Great Falls, Montana 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 4 run the early grades and stop. 7 districts hold the 15,393 homes counted here between them, and Great Falls High is the largest by homes. The largest share is high enough that one name is right for most of the homes counted and wrong for the other 345: 315 homes with Centerville High and Cascade High; 30 homes in districts too small to name here.

The early grades are divided four ways

4 districts hold a measurable share of ZIP Code 59405 at this level. Great Falls Elementary is the largest with 14,994 homes; the smallest of them holds 79 homes. Great Falls Elementary, Centerville Elementary, Cascade Elementary and one more district are named here for grade school and not for high school.

Every track below is 35 cells long and stands for all 15,393 homes counted in ZIP Code 59405, so one cell is 440 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: Highwood K-12 holds 5 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.

Three districts share high school

3 districts hold a measurable share of ZIP Code 59405 at this level. Great Falls High is the largest with 15,048 homes; the smallest of them holds 114 homes. Great Falls High, Centerville High and Cascade High are named here for high school and not for the early grades.

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.

Check an exact address with the Census Geocoder

Then confirm it with the district office. Each district named here, with its NCES district ID, website and phone:

The set of names changes in both directions

Great Falls High, Centerville High and Cascade High are named for high school here and for no elementary grades, and Great Falls Elementary, Centerville Elementary, Cascade Elementary and one more district 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 59405

A lookup that answers ZIP Code 59405 with one district name has to pick one of the names below and drop the rest. Measured against the 15,393 homes counted here, for the early grades it is wrong for 399 homes and for high school it is wrong for 345 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.

Look up 59405 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 59405 recomputes the same 15,393 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: 345 of the 15,393 homes counted in 59405 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.
