Pennsylvania · runs pre-K through grade 12

NCES ID 4218990 · philasd.org · (215) 400-4000

Philadelphia City spreads across 52 ZIP Code areas — enough that no single postal code describes it. It is the only district in 47 of them and shares 1 more; in the remaining 4 it holds under half a percent of the homes. In total it covers 726,815 homes over 134 square miles.

A district wide enough to cross many ZIP Codes

At 5,411 homes to the square mile this is city territory, and district lines in a city follow streets. Philadelphia City covers 134 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 19143 this district holds 100% of the homes; in 19428 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

Philadelphia City is the largest district in 48 ZIP Code areas. Answer with its name alone and the answer misses 57 of the 726,854 homes those areas hold — though in 46 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

ZIP Code 19118 · Philadelphia, Pennsylvania is a two-district area: 4,850 of its 4,887 homes are inside Philadelphia City, and the other 37 homes are with Springfield Township. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 19128 · Philadelphia, Pennsylvania the split runs 18,280 to 20 and the larger part is Philadelphia City's: the rest is 20 homes in a district too small to name here.

In ZIP Code 19102 · Philadelphia, Pennsylvania the single-name answer is the true one: Philadelphia City holds all 5,482 homes counted there, and no other district holds a share worth naming.

ZIP Code 19103 · Philadelphia, Pennsylvania is another area where one name covers everything — 21,071 homes, all of them inside Philadelphia City.

Who takes the other homes in its ZIP Codes

Philadelphia City 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 — Colonial, Lower Merion and Upper Merion Area. They are neighbors on the same postal ground, not the next stop for its own students.

  • Colonial School District12,946 homes in 2 shared ZIP Code areas
  • Lower Merion School District4,761 homes in 1 shared ZIP Code area
  • Upper Merion Area School District1,087 homes in 1 shared ZIP Code area
  • Springfield Township School District358 homes in 2 shared ZIP Code areas

Who it shares ZIP Codes with

One district shares ZIP Codes with Philadelphia City: Springfield Township, in 1 of them. For those areas a single-name lookup is choosing between exactly two answers, and it does not tell you it is choosing.

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 1 of the 52 ZIP Code areas Philadelphia City 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.
