Helena High School District

It never has a ZIP Code to itself

Helena High covers 1,361 square miles, and the ZIP Code areas inside it are small by comparison. Its 27,267 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 59633 this district holds 100% of the homes; in 59623 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

Helena High is the largest district in 7 ZIP Code areas. Answer with its name alone and the high school answer misses 1,780 of the 28,826 homes those areas hold — though in 4 of them it holds every home there is for high school. The count is homes, not addresses, and it is the number no lookup prints.

ZIP Code 59602 · Helena Valley Northeast, Montana is a two-district area for high school: 11,184 of its 12,619 homes are inside Helena High, and the other 1,435 homes are with East Helena K-12. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 59601 · Helena, Montana the split runs 14,949 to 330 and the larger part is Helena High's: the rest is 330 homes with East Helena K-12.

Helena High holds 630 of the 645 homes in ZIP Code 59648 · Milford Colony, Montana, so its name is the right high school answer for most of the area and the wrong one for the rest: 15 homes with Augusta High.

Helena High holds all 32 homes counted for high school in ZIP Code 59625 · Helena, Montana, and no other high school district holds a share worth naming. For grade school the same homes are named for Helena Elementary (32 homes), so a single name answers only one of the two questions there.

ZIP Code 59633 · Canyon Creek, Montana is another area where Helena High holds every home counted for high school — 168 homes — and for grade school the same homes are named for Trinity Elementary (168 homes).

In ZIP Code 59421 · Hardy, Montana this district is one name among 4. Cascade High leads with the largest share and Helena High holds 193 of the 1,469 homes counted there; no single name describes that area at all.

Helena High is not the name anyone would give for ZIP Code 59639 · Lincoln, Montana — Lincoln K-12 Schools leads it — and Helena High holds 21 homes there all the same. Answer that area with one name and that is what it is wrong about.

The elementary districts that feed it

Students arrive at Helena High from 6 districts that run the lower grades in the same ZIP Code areas — Helena Elementary, which sends 94%, Trinity Elementary, which sends 3.4% and Wolf Creek Elementary, which sends 2.3%. An address on that ground belongs to two districts at once, one for grade school and this one for high school, and neither name is the whole answer.

This list is an estimate, names as well as percentages. The snapshot behind this site keeps the homes each district holds in each ZIP Code area, not the pair of districts on each census block, so a district is listed here when it runs the other band in a ZIP Code area this one shares, and each percentage spreads that area's homes across those districts in proportion to the share each holds there. Unified districts are left out: a block in a unified district belongs to no elementary or secondary district. Read the percentages as the size of the crossing, not as a count of houses.

Who it shares ZIP Codes with

Helena High shares ZIP Code areas with 9 different districts. The most frequent are Helena Elementary, Trinity Elementary, East Helena K-12 and Wolf Creek Elementary.

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.

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: in 9 of the 11 ZIP Code areas Helena 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.

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.

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.
