ZIP Code 93550 · Palmdale, California
Los Angeles County · 24,636 counted · 3 districts
Each percentage here is a share of the 24,636 homes counted in ZIP Code 93550, 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 93550, Palmdale, 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 1 serves both bands. 3 districts hold the 24,636 homes counted here between them, and Antelope Valley Union Joint 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 235: 230 homes with Acton-Agua Dulce Unified and 5 homes in districts too small to name here.
The early grades are split between two districts
2 districts hold a measurable share of ZIP Code 93550 at this level. Palmdale Elementary is the largest with 24,391 homes; the smallest of them holds 230 homes. Palmdale Elementary is named here for grade school and not for high school.
Every track below is 35 cells long and stands for all 24,636 homes counted in ZIP Code 93550, so one cell is 704 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.
- Palmdale Elementary School District24,391 of 24,636 homes99%
- Acton-Agua Dulce Unified School District230 of 24,636 homes0.9%
Below half a percent at the grade school level: Keppel Union Elementary School District, La Cañada Unified School District and Eastside Union Elementary School District, and one more hold 15 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.
Azusa Unified School District, Pasadena Unified School District and Snowline Joint Unified School District reach into ZIP Code 93550 at the grade school level as well and hold 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.

- Antelope Valley Union Joint High School District NCES ID 0602820 avdistrict.org (661) 948-7655
- Palmdale Elementary School District NCES ID 0629580 palmdalesd.org (661) 947-7191

The set of names changes in both directions
Antelope Valley Union Joint High is named for high school here and for no elementary grades, and Palmdale 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 93550

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.

The lookup holds every ZIP Code area in the country with homes in it, including the ones with no page of their own.

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: 235 of the 24,636 homes counted in 93550 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.
