Each percentage here is a share of the 17,030 homes counted in ZIP Code 95127, 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 95127, San Jose, California are not the districts named for high school, and the set changes in both directions: 1 district arrives for high school that no elementary answer names, and 3 run the early grades and stop. 4 districts hold the 17,030 homes counted here between them, and East Side Union High is the largest by homes. The area sits in Santa Clara County, California.

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:

  • East Side Union High School District NCES ID 0611820 esuhsd.org (408) 347-5000
  • Alum Rock Union Elementary School District NCES ID 0602310 arusd.org (408) 928-6800
  • Mount Pleasant Elementary School District NCES ID 0626400 mpesd.org (408) 223-3710
  • Berryessa Union Elementary School District NCES ID 0604800 berryessa.k12.ca.us (408) 923-1800

The set of names changes in both directions

East Side Union High is named for high school here and for no elementary grades, and Alum Rock Union Elementary, Mount Pleasant Elementary and Berryessa Union Elementary 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 95127

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: one district covers every home counted in 95127, and even then the street is what enrolls a child, because magnet, charter and choice programs ignore the boundary entirely.

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.
