Missoula High School District

It never has a ZIP Code to itself

Missoula High covers 2,046 square miles, and the ZIP Code areas inside it are small by comparison. Its 50,623 homes are spread thinly enough that the postal map and the school map have little reason to agree anywhere.

The ZIP Code areas it reaches

The spread is the thing to notice. In 59801 this district holds 100% of the homes; in 59821 it holds no homes at all. Same district, opposite answers, and a lookup that names it without the share tells the second household the same thing as the first.

What one name misses, and what changes later

Missoula High is the largest district in 9 ZIP Code areas. Answer with its name alone and the answer misses 1,642 of the 36,610 homes those areas hold — though in 4 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

Missoula High holds 8,346 of the 9,665 homes in ZIP Code 59808 · Missoula, Montana, so its name is right for most of the area and wrong for the rest: 1,319 homes with Frenchtown K-12 Schools and Arlee High.

In ZIP Code 59825 · Clinton, Montana the split runs 904 to 264 and the larger part is Missoula High's: the rest is 264 homes with Drummond High and Philipsburg K-12 Schools.

ZIP Code 59868 · Seeley Lake, Montana is a two-district area: 1,551 of its 1,558 homes are inside Missoula High, and the other 7 homes are in a district too small to name here. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 59804 · Orchard Homes, Montana the split runs 3,376 to 1 and the larger part is Missoula High's: the rest is 1 home in a district too small to name here.

In ZIP Code 59802 · Missoula, Montana the single-name answer is the true one: Missoula High holds all 9,992 homes counted there, and no other district holds a share worth naming.

ZIP Code 59801 · Missoula, Montana is close to being two districts in equal parts: Missoula High holds 15,384 of its 15,384 homes and Missoula Elementary leads the rest. A lookup that picks the larger name is making a coin-toss look like a fact.

Missoula High is not the name anyone would give for ZIP Code 59911 · Bigfork, Montana — Bigfork High leads it — and Missoula High holds 143 homes there all the same. Answer that area with one name and that is what it is wrong about.

ZIP Code 59851 · Bonner-West Riverside, Montana is another area where Missoula High is present without being the answer: 94 of its 94 homes, behind Bonner Elementary.

The elementary districts that feed it

Students arrive at Missoula High from 6 districts that run the lower grades on the same ground — Missoula Elementary, which sends 65%, Hellgate Elementary, which sends 13% and Lolo Elementary, which sends 4.5%. Each of those addresses therefore belongs to two districts at once, one for grade school and this one for high school, and neither name is the whole answer.

• Missoula Elementary School District65% of Missoula High's homes come from here
• Hellgate Elementary School District13% of Missoula High's homes come from here
• Lolo Elementary School District4.5% of Missoula High's homes come from here
• Target Range Elementary School District3.4% of Missoula High's homes come from here
• Seeley Lake Elementary School District2.9% of Missoula High's homes come from here
• Bonner Elementary School District2.7% of Missoula High's homes come from here

The names in this list are exact: the federal file gives the district of each band for every census block. The percentages are not. They spread each shared ZIP Code area's homes across the other band in proportion to the share each district holds there, because the file names the two districts of a block and not how a household moves between them. Read them as the size of the crossing, not as a count of houses.

Who it shares ZIP Codes with

Missoula High shares ZIP Code areas with 30 different districts. The most frequent are Missoula Elementary, Bonner Elementary, Sunset Elementary and Swan Valley Elementary. In a neighborhood this crowded the question is not which district serves the ZIP Code but which side of which street an address is on.

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: in 14 of the 15 ZIP Code areas Missoula High reaches, at least one other district holds a real share of the homes as well, and the line between 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.
