Alvord Unified School District

It never has a ZIP Code to itself

At 1,036 homes to the square mile this is city territory, and district lines in a city follow streets. Alvord Unified covers 32 square miles in all — small enough that a single ZIP Code area can hold most of it, and several ZIP Codes can cut across it.

The ZIP Code areas it reaches

The spread is the thing to notice. In 92505 this district holds 97% of the homes; in 91752 it holds no homes at all. Same district, opposite answers, and a lookup that names it without the share tells the second household the same thing as the first.

What one name misses in the areas it leads

Alvord Unified is the largest district in 2 ZIP Code areas, and not one of them is wholly its own. Answer with its name alone and the answer misses 11,769 of the 41,627 homes those areas hold. That count is computed here from census blocks; the lookups that answer this question with a single name never print it.

Alvord Unified holds 14,772 of the 26,153 homes in ZIP Code 92503 · Riverside, California, so its name is right for most of the area and wrong for the rest: 11,381 homes with Riverside Unified.

In ZIP Code 92505 · Riverside, California the split runs 15,086 to 388 and the larger part is Alvord Unified's: the rest is 388 homes with Riverside Unified.

Alvord Unified reaches into ZIP Code 92879 · Corona, California with 2,796 of its 14,526 homes, behind Corona-Norco Unified. The familiar answer for that area is the other name, and it is wrong for those 2,796 homes.

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.

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: in 3 of the 7 ZIP Code areas Alvord Unified reaches, at least one other district holds a real share of the homes as well, and the line between them runs along streets. Only the district can say which side of that line an address is on.

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.

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.
