ZIP Code 92154 · San Diego, California
San Diego County · 23,036 counted · 4 districts
Each percentage here is a share of the 23,036 homes counted in ZIP Code 92154, 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 92154, San Diego, 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 23,036 homes counted here between them, and Sweetwater Union High is the largest by homes. The area sits in San Diego County, California.

Have a street address?

The set of names changes in both directions
Sweetwater Union High is named for high school here and for no elementary grades, and South Bay Union, Chula Vista Elementary and San Ysidro 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 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 92154, 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.
