Pittsburgh School District

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

At 2,919 homes to the square mile this is city territory, and district lines in a city follow streets. Pittsburgh covers 55 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 15217 this district holds 100% of the homes; in 15290 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.

The areas it leads without holding most of the homes

Pittsburgh is the largest district in 22 ZIP Code areas. Answer with its name alone and the answer misses 15,785 of the 165,262 homes those areas hold — though in 12 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

Pittsburgh is the largest name in ZIP Code 15216 · Pittsburgh, Pennsylvania and still holds a minority of it: 4,315 of 11,568 homes. The other 7,253 homes are with Keystone Oaks, Mount Lebanon and Chartiers Valley. This is the shape that makes a one-name answer worst — the name is right for fewer homes than it is wrong for.

ZIP Code 15220 · Pittsburgh, Pennsylvania repeats the pattern with 3 names holding a real share: 3,831 of its 8,960 homes are Pittsburgh's, and the other 5,129 are not.

Pittsburgh holds 5,233 of the 6,802 homes in ZIP Code 15214 · Pittsburgh, Pennsylvania, so its name is right for most of the area and wrong for the rest: 1,569 homes with North Hills and Shaler Area.

In ZIP Code 15212 · Pittsburgh, Pennsylvania the split runs 14,360 to 1,083 and the larger part is Pittsburgh's: the rest is 1,083 homes with Shaler Area and North Hills.

ZIP Code 15210 · Pittsburgh, Pennsylvania is a two-district area: 12,501 of its 12,558 homes are inside Pittsburgh, and the other 57 homes are in a district too small to name here. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 15205 · Pittsburgh, Pennsylvania this district is one name among 4. Montour leads with the largest share and Pittsburgh holds 3,437 of the 12,239 homes counted there; no single name describes that area at all.

Pittsburgh reaches into ZIP Code 15221 · Wilkinsburg, Pennsylvania with 2,472 of its 16,979 homes; 3 districts there hold a real share of it, and Wilkinsburg Borough leads them. The familiar answer for that area is one of the others, and it is wrong for those 2,472 homes.

ZIP Code 15227 · Baldwin, Pennsylvania is another area where Pittsburgh is present without being the answer: 1,505 of its 13,646 homes, behind Baldwin-Whitehall.

Who takes the other homes in its ZIP Codes

Pittsburgh 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 — Woodland Hills, Penn Hills and Keystone Oaks. They are neighbors on the same postal ground, not the next stop for its own students.

• Woodland Hills School District14,657 homes in 3 shared ZIP Code areas
• Penn Hills School District13,752 homes in 1 shared ZIP Code area
• Keystone Oaks School District10,755 homes in 5 shared ZIP Code areas
• Wilkinsburg Borough School District9,187 homes in 2 shared ZIP Code areas
• Steel Valley School District8,733 homes in 1 shared ZIP Code area
• Chartiers Valley School District8,412 homes in 3 shared ZIP Code areas

Who it shares ZIP Codes with

Pittsburgh shares ZIP Code areas with 16 different districts. The most frequent are Keystone Oaks, Baldwin-Whitehall, Chartiers Valley and Mount Lebanon. In a neighborhood this crowded the question is not which district serves the ZIP Code but which side of which street an address is on.

What to do next

Ask the district office to confirm your street address. A district settles that question on its own site: look for a school locator, a find my school tool, or an attendance zone map. Where there is none, ask the office itself.

A ZIP Code is a set of mail delivery routes, not a boundary: in 13 of the 32 ZIP Code areas Pittsburgh 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.

This site links to no district website. None of the federal files it is built from publishes one, and a guessed address is worse than none. It is the district office, not a search engine, that settles an address.

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.

What this cannot tell you

The homes were counted in the 2020 Census and the district lines are the 2026 boundary file. Nothing on this page adjusts one to the other. Where houses have been built or cleared since the count, a share here describes the place as it was counted rather than as it stands today, and in the fastest-growing ZIP Code areas that gap is the largest single source of error on this site.

A share on this page is a share of the homes in the ZIP Code area, not a probability for any particular address. Enrollment is decided by street address, and a district may run magnet, charter or choice programs that ignore the boundary entirely. If a decision depends on the answer, the district office is the only authority; this page shows what the federal boundary files say and when they were published.

A district boundary is not a school attendance zone. This site never says which school an address is assigned to: no current national dataset of attendance zones exists, and the district draws them itself. Nor is anything here endorsed or certified by the Census Bureau; we use their published files, and that is the whole of the relationship.

A ZIP Code is a set of mail delivery routes, not an area. What is mapped here is the Census Bureau's ZIP Code Tabulation Area, the closest published approximation to it. The two are not identical, and a handful of ZIP Codes used only for post office boxes or single buildings have no tabulation area at all.

Where these numbers come from

School district boundaries come from the Census Bureau's Census Geographic Relationship File, current 2026 vintage, which assigns every census block to a unified district or to an elementary and a secondary district. Homes and residents in each block come from the 2020 Census Redistricting Data (PL 94-171), H1_001 and P1_001. The ZIP Code areas come from the same Geographic Relationship File, block to ZIP Code Tabulation Area. District names and grade ranges come from the Census Gazetteer 2025, with 2020 for districts no longer listed.

The place name printed beside a ZIP Code comes from the Census 2020 ZIP Code Tabulation Area relationship files: place, county subdivision and county, taken 2026-09-06. It is a label rather than a measurement: the Census Bureau does not publish which post office a ZIP Code belongs to, so the place named is the one covering the most land inside the area, not the city the Postal Service prints on an envelope.

Everything else on this page — the shares, the counts of districts per ZIP, the comparison between the two grade bands, the rankings — is computed here from those files. The source publishes none of it. Snapshot taken 2026-09-03.
