ZIP Code 92028 · Fallbrook, California
San Diego County · 18,426 counted · 4 districts
Each percentage here is a share of the 18,426 homes counted in ZIP Code 92028, 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 92028, Fallbrook, California are not the districts named for high school, and the set changes in both directions: 1 district arrives for high school only, 2 run the early grades and stop, and 1 serves both bands. 4 districts hold the 18,426 homes counted here between them, and Fallbrook Union High is the largest by homes. The largest share leaves 2,289 homes elsewhere: 2,278 homes with Bonsall Unified and 11 homes in districts too small to name here. Districts holding under half a percent of the homes named at their own level are listed separately below and are not counted in that number.
Three districts share the early grades
3 districts hold a measurable share of ZIP Code 92028 at this level. Fallbrook Union Elementary is the largest with 15,291 homes; the smallest of them holds 846 homes. Fallbrook Union Elementary and Vallecitos Elementary are named here for grade school and not for high school.
Every track below is 35 cells long and stands for all 18,426 homes counted in ZIP Code 92028, so one cell is 526 homes, rounded to the nearest whole cell. Cells lit solid are the homes one district holds, and the unlit cells are the homes held by the other districts in the same list.

- Vallecitos Elementary School District846 of 18,426 homes4.6%
Below half a percent at the grade school level: Murrieta Valley Unified School District and Valley Center-Pauma Unified School District hold 11 homes between them, which is why they are counted under the list rather than inside it. A lookup that named them alongside the districts above would be listing a boundary crossing rather than an answer.
High school is split between two districts
2 districts hold a measurable share of ZIP Code 92028 at this level. Fallbrook Union High is the largest with 16,137 homes; the smallest of them holds 2,278 homes. Fallbrook Union High is named here for high school and not for the early grades.

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.

The set of names changes in both directions
Fallbrook Union High is named for high school here and for no elementary grades, and Fallbrook Union Elementary and Vallecitos 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 92028
A lookup that answers ZIP Code 92028 with one district name has to pick one of the names below and drop the rest. Measured against the 18,426 homes counted here, for the early grades it is wrong for 3,135 homes and for high school it is wrong for 2,289 homes. That is the whole difference between this page and a one-line answer: the same federal file, read to the end instead of to the first row.

Look up 92028 again, or look up another ZIP Code
The lookup holds every ZIP Code area in the country with homes in it, including the ones with no page of their own. Opening it at 92028 recomputes the same 18,426 homes from the same snapshot, and typing five other digits answers for somewhere else. No server is asked for the answer: the whole index travels with the lookup page itself.
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: 2,289 of the 18,426 homes counted in 92028 sit outside the district holding the most of them, and the line between the two runs along streets rather than around the postal area.
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.
