West Allis School District

Wisconsin · runs pre-K through grade 12

NCES ID 5516260 · wawmsd.org · (414) 604-3000

There is no ZIP Code area where West Allis is the only school district serving the homes. It holds a real share in 6 of them and shares every one, with 5 different districts in total. A lookup that returns a single district name for any of those ZIP Codes is guessing which side of a line an address falls on.

It never has a ZIP Code to itself

At 2,387 homes to the square mile this is city territory, and district lines in a city follow streets. West Allis covers 14 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.

What one name misses in the areas it leads

West Allis 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 4,702 of the 28,110 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.

ZIP Code 53214 · West Allis, Wisconsin is a two-district area: 13,820 of its 16,706 homes are inside West Allis, and the other 2,886 homes are with Milwaukee. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 53227 · West Allis, Wisconsin the split runs 9,588 to 1,816 and the larger part is West Allis': the rest is 1,816 homes with Milwaukee.

West Allis reaches into ZIP Code 53219 · Milwaukee, Wisconsin with 7,669 of its 16,080 homes; 3 districts there hold a real share of it, and Milwaukee leads them. The familiar answer for that area is one of the others, and it is wrong for those 7,669 homes.

West Allis is not the name anyone would give for ZIP Code 53151 · New Berlin, Wisconsin — New Berlin leads it — and West Allis holds 1,306 homes there all the same. Answer that area with one name and that is what it is wrong about.

ZIP Code 53215 · Milwaukee, Wisconsin is another area where West Allis is present without being the answer: 243 of its 21,135 homes, behind Milwaukee.

Who takes the other homes in its ZIP Codes

They are neighbors on the same postal ground, not the next stop for its own students.

Who it shares ZIP Codes with

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 6 of the 7 ZIP Code areas West Allis 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.
