ZIP Code 94044 · Pacifica, California
San Mateo County · 14,670 counted · 3 districts
Each percentage here is a share of the 14,670 homes counted in ZIP Code 94044, 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 94044, Pacifica, 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 2 run the early grades and stop. 3 districts hold the 14,670 homes counted here between them, and Jefferson Union High is the largest by homes. 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. The area sits in San Mateo County, California.
The early grades are split between two districts
2 districts hold a measurable share of ZIP Code 94044 at this level. Pacifica is the largest with 14,321 homes; the smallest of them holds 349 homes. Pacifica and Jefferson Elementary are named here for grade school and not for high school.

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:
- Jefferson Union High School District NCES ID 0618930 juhsd.net (650) 550-7900
- Pacifica School District NCES ID 0620460 pacificasd.org (650) 738-6600
- Jefferson Elementary School District NCES ID 0618870 jsd.k12.ca.us (650) 991-1000
The set of names changes in both directions
Jefferson Union High is named for high school here and for no elementary grades, and Pacifica and Jefferson 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 94044
A lookup that answers ZIP Code 94044 with one district name has to pick one of the names below and drop the rest. Measured against the 14,670 homes counted here, for the early grades it is wrong for 349 homes and for high school one name is right for every home counted. 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.

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 94044, 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.
