Plainfield City School District

It never has a ZIP Code to itself

At 2,874 homes to the square mile this is city territory, and district lines in a city follow streets. Plainfield City covers 6 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 07062 this district holds 91% of the homes; in 08812 it holds 0.7% of the homes. 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

Plainfield City is the largest district in 3 ZIP Code areas, and not one of them is wholly its own. Answer with its name alone and the answer misses 8,065 of the 25,154 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.

Plainfield City holds 9,443 of the 15,933 homes in ZIP Code 07060 · Plainfield, New Jersey, so its name is right for most of the area and wrong for the rest: 6,482 homes with North Plainfield Borough and 8 homes in a district too small to name here.

In ZIP Code 07063 · Plainfield, New Jersey the split runs 3,090 to 1,136 and the larger part is Plainfield City's: the rest is 1,134 homes with North Plainfield Borough and 2 homes in a district too small to name here.

ZIP Code 07062 · Plainfield, New Jersey is a two-district area: 4,556 of its 4,995 homes are inside Plainfield City, and the other 439 homes are with North Plainfield Borough. Which one an address belongs to is settled by the street, not by the five digits.

Plainfield City is not the name anyone would give for ZIP Code 08812 · Dunellen, New Jersey — Dunellen Borough leads it — and Plainfield City holds 36 homes there all the same. Answer that area with one name and that is what it is wrong about.

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.

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 4 of the 4 ZIP Code areas Plainfield 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.
