There is no ZIP Code area where East Side Union High is the only school district serving the homes. It holds a real share in 21 of them and shares every one, with 14 different districts in total. A lookup that returns a single district name for any of those ZIP Codes is guessing which side of a line an address falls on.
It never has a ZIP Code to itself
At 1,167 homes to the square mile this is city territory, and district lines in a city follow streets. East Side Union High covers 139 square miles in all — small enough that a single ZIP Code area can hold most of it, and several ZIP Codes can cut across it.

The ZIP Code areas it reaches
The spread is the thing to notice. In 95127 this district holds 100% of the homes; in 95120 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
East Side Union High is the largest district in 15 ZIP Code areas. Answer with its name alone and the high school answer misses 18,019 of the 172,885 homes those areas hold — though in 5 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 95123 · San Jose, California is a two-district area for high school: 18,494 of its 24,996 homes are inside East Side Union High, and the other 6,502 homes are with San Jose Unified. Which one an address belongs to is settled by the street, not by the five digits.
In ZIP Code 95136 · San Jose, California the split runs 10,504 to 5,947 and the larger part is East Side Union High's: the rest is 5,947 homes with San Jose Unified.
East Side Union High holds 3,209 of the 3,292 homes in ZIP Code 95119 · San Jose, California, so its name is the right high school answer for most of the area and the wrong one for the rest: 83 homes with Morgan Hill Unified.
East Side Union High is one of 4 high school districts the file names for ZIP Code 95140 · Santa Clara County, California.

East Side Union High reaches into ZIP Code 95134 · San Jose, California with 2,754 of its 14,100 homes; 3 districts there hold a real share of it, and Santa Clara Unified leads them. The familiar answer for that area is one of the others, and it is wrong for those 2,754 homes.
East Side Union High is not the name anyone would give for ZIP Code 95125 · San Jose, California — San Jose Unified leads it — and East Side Union High holds 1,007 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 East Side Union High from 6 districts that run the lower grades in the same ZIP Code areas — Oak Grove Elementary, which sends 23%, Alum Rock Union Elementary, which sends 18% and Evergreen Elementary, which sends 18%. 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.

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.
Where this district sits
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 21 of the 22 ZIP Code areas East Side Union 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.
