DistrictByZip Every school district that touches your ZIP Code

How do I find my school district number?

There are three different numbers people mean by it, and they are not interchangeable: the federal NCES district ID, which every district in the country has; the code a state education agency gives its own districts; and, in a few states, a school district code for the state income tax return. This site prints the first one for each of the 13,257 school districts that hold a measurable share of a ZIP Code area, on every district page and in every ZIP Code answer. Of the other 211 in the Census boundary files, 22 reach a ZIP Code area only below half a percent of the homes named at their level and are counted there without a name, and 189 are linked to no ZIP Code area in the block files this site is built from.

The NCES district ID

The National Center for Education Statistics gives every public school district a seven-digit ID, the LEAID. The first two digits are the state FIPS code and the other five number the district. Fayetteville School District, for example, is 0506120: the leading 05 is the code of Arkansas, and the rest numbers the district inside it. The Census Bureau files school district boundaries under the same seven digits, which is why this site can match a boundary to a district website without guessing by name.

To find it: look up your ZIP Code here and the answer lists each district with its NCES ID, website and phone; or open a district page, where the ID stands under the name. 13,221 of the 13,468 districts in the boundary files are in the NCES Common Core of Data directory for 2024-25.

The state district code

Each state education agency numbers its own districts, and that code is what state report cards, enrollment forms and state data files use. It follows no national pattern: some states use four digits, some put a county number first, some add letters. The NCES directory carries the state code beside the federal ID, so either one leads to the other, but this site does not print state codes and does not convert between them.

The school district code on a tax return

When a tax form asks for a school district number, it means the state's own tax code, and neither the NCES ID nor this site can supply it. A wrong code there costs a corrected return, so take it from the state that sets it. These are the official lookups, each with the day it was last opened and checked:

Other states that tie income tax to the school district publish their own tables in the instructions to the state return. The tax code follows the address, not the ZIP Code, for the same reason the district does: 17,865 of the 33,555 ZIP Code areas with homes are served by more than one school district.

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: 17,865 of the 33,555 ZIP Code areas in the country with homes in them are served by more than one school district, and the line between two of 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.
