The areas it leads without holding most of the homes

Answer with its name alone and the high school answer misses 13,288 of the 26,708 homes those areas hold. That count is computed here from census blocks; the lookups that answer this question with a single name never print it.

Alhambra Unified School District (9-12) holds 8,969 of the 17,412 homes in ZIP Code 91770 · Rosemead, California, so its name is the right high school answer for most of the area and the wrong one for the rest: 8,417 homes with El Monte Union High and Montebello Unified; 26 homes in a district too small to name here.

Alhambra Unified School District (9-12) is the largest name in ZIP Code 91755 · Monterey Park, California and still holds a minority of it: 4,451 of 9,296 homes.

In ZIP Code 91776 · San Gabriel, California this district is one name among 5. San Gabriel Unified leads with the largest share and Alhambra Unified School District (9-12) holds 1,804 of the 12,674 homes counted there; no single name describes that area at all.

The elementary districts that feed it

Students arrive at Alhambra Unified School District (9-12) from 2 districts that run the lower grades in the same ZIP Code areas — Garvey Elementary, which sends 72% and Rosemead Elementary, which sends 28%.

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.

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 3 of the 4 ZIP Code areas Alhambra Unified School District (9-12) 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.
