Fairfax County Public Schools

Virginia · runs pre-K through grade 12

NCES ID 5101260 · fcps.edu · (571) 423-1010

Fairfax County covers 427,149 of the homes in 49 ZIP Code areas, but its smallest measured presence is a different thing entirely: in ZIP Code area 22304 it holds 148 of 24,596 homes, or 0.6% of them. An address in that ZIP Code is almost certainly not in this district, and a lookup that names the district without the share says the opposite. Below the half-percent line this page draws it reaches 1 further ZIP Code area, the least of them 48 homes in 22207.

A few homes at the edge of someone else's ZIP Code

At 1,092 homes to the square mile this is city territory, and district lines in a city follow streets. Fairfax County covers 391 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 22003 this district holds 100% of the homes; in 22207 it holds 48 homes, under half a percent. 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

Fairfax County is the largest district in 43 ZIP Code areas. Answer with its name alone and the answer misses 13,860 of the 437,331 homes those areas hold — though in 34 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

ZIP Code 22030 · Braddock, Virginia is a two-district area: 14,033 of its 20,959 homes are inside Fairfax County, and the other 6,926 homes are with Fairfax City. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 22312 · Lincolnia, Virginia the split runs 8,587 to 3,129 and the larger part is Fairfax County's: the rest is 3,129 homes with Alexandria City.

In ZIP Code 20121 · Bull Run, Virginia the single-name answer is the true one: Fairfax County holds all 10,349 homes counted there, and no other district holds a share worth naming.

ZIP Code 20124 · Union Mill, Virginia is another area where one name covers everything — 5,020 homes, all of them inside Fairfax County.

Fairfax County reaches into ZIP Code 22046 · Falls Church, Virginia with 2,046 of its 7,203 homes, behind Falls Church City. The familiar answer for that area is the other name, and it is wrong for those 2,046 homes.

Fairfax County is not the name anyone would give for ZIP Code 22302 · Alexandria, Virginia — Alexandria City leads it — and Fairfax County holds 679 homes there all the same. Answer that area with one name and that is what it is wrong about.

ZIP Code 22311 · Alexandria, Virginia is another area where Fairfax County is present without being the answer: 611 of its 9,172 homes, behind Alexandria City.

Who takes the other homes in its ZIP Codes

Fairfax County 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 — Alexandria City, Arlington County and Fairfax City. They are neighbors on the same postal ground, not the next stop for its own students.

Arlington County Public Schools26,482 homes in 2 shared ZIP Code areas
Fairfax City Public Schools9,330 homes in 3 shared ZIP Code areas

Who it shares ZIP Codes with

These districts appear alongside Fairfax County in the same ZIP Code areas: Alexandria City, Fairfax City, Falls Church City and Loudoun County. 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.

Where this district sits

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 13 of the 49 ZIP Code areas Fairfax County 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.
