Each percentage here is a share of the 26,596 homes counted in ZIP Code 92336, 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 92336, Fontana, California are not the districts named for high school, and the set changes in both directions: 1 district arrives for high school only, 1 runs the early grades and stops, and 2 serve both bands. 4 districts hold the 26,596 homes counted here between them, and Fontana Unified is the largest by homes. The largest share leaves 10,679 homes elsewhere: 10,679 homes with Etiwanda Elementary and Rialto Unified. The area sits in San Bernardino 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:

  • Fontana Unified School District NCES ID 0613920 fusd.net (909) 357-7600
  • Chaffey Joint Union High School District NCES ID 0608160 cjuhsd.net (909) 988-8511
  • Etiwanda Elementary School District NCES ID 0612960 etiwanda.k12.ca.us (909) 899-2451
  • Rialto Unified School District NCES ID 0632370 kec.rialto.k12.ca.us (909) 820-7700

The set of names changes in both directions

Chaffey Joint Union High is named for high school here and for no elementary grades, and Etiwanda Elementary runs 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 92336

A lookup that answers ZIP Code 92336 with one district name has to pick one of the names below and drop the rest. Measured against the 26,596 homes counted here, for the early grades it is wrong for 10,679 homes and for high school it is wrong for 10,679 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 92336 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 92336 recomputes the same 26,596 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: 10,679 of the 26,596 homes counted in 92336 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.
