Where this district is the answer, and where it is not

At 4,311 homes to the square mile this is city territory, and district lines in a city follow streets. Seattle covers 86 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 98103 this district holds 100% of the homes; in 98174 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 an answer of one district name misses here

Seattle is the largest district in 26 ZIP Code areas. Answer with its name alone and the answer misses 11,547 of the 372,049 homes those areas hold — though in 22 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

ZIP Code 98133 · Shoreline, Washington is a two-district area: 13,527 of its 23,778 homes are inside Seattle, and the other 10,251 homes are with Shoreline. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 98106 · Seattle, Washington the split runs 10,234 to 940 and the larger part is Seattle's: the rest is 940 homes with Highline.

In ZIP Code 98101 · Seattle, Washington the single-name answer is the true one: Seattle holds all 11,888 homes counted there, and no other district holds a share worth naming.

ZIP Code 98102 · Seattle, Washington is another area where one name covers everything — 16,957 homes, all of them inside Seattle.

ZIP Code 98177 · Shoreline, Washington is close to being two districts in equal parts: Seattle holds 3,413 of its 8,076 homes and Shoreline leads the rest. A lookup that picks the larger name is making a coin-toss look like a fact.

Seattle reaches into ZIP Code 98178 · Bryn Mawr-Skyway, Washington with 2,644 of its 9,818 homes; 3 districts there hold a real share of it, and Renton leads them. The familiar answer for that area is one of the others, and it is wrong for those 2,644 homes.

Seattle reaches into ZIP Code 98146 · Burien, Washington with 2,016 of its 10,983 homes, behind Highline. The familiar answer for that area is the other name, and it is wrong for those 2,016 homes.

Who takes the other homes in its ZIP Codes

Seattle runs pre-K through grade 12 itself, so an address it holds sees no change of authority between grade school and high school. The districts listed below are the ones that take the other homes in the ZIP Code areas it shares — Shoreline, Highline and Lake Washington. They are neighbors on the same postal ground, not the next stop for its own students.

• Shoreline School District29,575 homes in 3 shared ZIP Code areas
• Highline School District19,090 homes in 5 shared ZIP Code areas
• Lake Washington School District18,570 homes in 1 shared ZIP Code area
• Renton School District6,733 homes in 1 shared ZIP Code area
• Tukwila School District4,665 homes in 2 shared ZIP Code areas

Who it shares ZIP Codes with

These districts appear alongside Seattle in the same ZIP Code areas: Highline, Shoreline, Renton and Tukwila. A single-name lookup for one of those areas has to choose between them, and the choice is right for some addresses and wrong for others.

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 7 of the 34 ZIP Code areas Seattle 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.
