ZIP Code 93036 · Oxnard, California
Ventura County · 15,095 counted · 4 districts
Each percentage here is a share of the 15,095 homes counted in ZIP Code 93036, 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 93036, Oxnard, 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 15,095 homes counted here between them, and Oxnard Union High is the largest by homes. The largest share is high enough that one name is right for most of the homes counted and wrong for the other 1: 1 home in districts too small to name here.
Three districts share the early grades
3 districts hold a measurable share of ZIP Code 93036 at this level. Rio Elementary is the largest with 11,099 homes; the smallest of them holds 159 homes. Rio Elementary, Oxnard Elementary and Mesa Union Elementary are named here for grade school and not for high school.

Ventura Unified School District reaches into ZIP Code 93036 at the grade school level as well and holds no home counted in it: the boundary crosses the postal area without picking up a single one.

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.

Then confirm it with the district office. Each district named here, with its NCES district ID, website and phone:
- Oxnard Union High School District NCES ID 0629270 oxnardunion.org (805) 385-2500
- Rio Elementary School District NCES ID 0632760 rioschools.org (805) 485-3111

- Mesa Union Elementary School District NCES ID 0624720 mesaschool.org (805) 485-1411
The set of names changes in both directions
Oxnard Union High is named for high school here and for no elementary grades, and Rio Elementary, Oxnard Elementary and Mesa 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 93036
A lookup that answers ZIP Code 93036 with one district name has to pick one of the names below and drop the rest. Measured against the 15,095 homes counted here, for the early grades it is wrong for 3,996 homes and for high school it is wrong for 1 home. 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 93036 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.

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: 1 of the 15,095 homes counted in 93036 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.
