The ZIP Code areas it reaches

The spread is the thing to notice. In 21702 this district holds 100% of the homes; in 21705 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

Frederick County is the largest district in 27 ZIP Code areas. Answer with its name alone and the answer misses 7,377 of the 108,686 homes those areas hold — though in 22 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

Frederick County is the largest name in ZIP Code 21771 · Green Valley, Maryland and still holds a minority of it: 4,884 of 10,942 homes. The other 6,058 homes are with Carroll County, Howard County and Montgomery County. 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 21758 · Garretts Mill, Maryland is a two-district area: 1,122 of its 1,848 homes are inside Frederick County, and the other 726 homes are with Washington County. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 21757 · Carroll County, Maryland the split runs 620 to 542 and the larger part is Frederick County's: the rest is 542 homes with Carroll County.

In ZIP Code 21701 · Frederick, Maryland the single-name answer is the true one: Frederick County holds all 17,680 homes counted there, and no other district holds a share worth naming.

ZIP Code 21702 · Frederick, Maryland is another area where one name covers everything — 17,813 homes, all of them inside Frederick County.

ZIP Code 21791 · Union Bridge, Maryland is close to being two districts in equal parts: Frederick County holds 948 of its 2,088 homes and Carroll County leads the rest. A lookup that picks the larger name is making a coin-toss look like a fact.

Frederick County reaches into ZIP Code 21783 · Cavetown, Maryland with 488 of its 3,616 homes, behind Washington County. The familiar answer for that area is the other name, and it is wrong for those 488 homes.

ZIP Code 21776 · New Windsor, Maryland is another area where Frederick County is present without being the answer: 265 of its 2,241 homes, behind Carroll County.

Who takes the other homes in its ZIP Codes

Frederick 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 — Carroll County, Montgomery County and Washington County. They are neighbors on the same postal ground, not the next stop for its own students.

Who it shares ZIP Codes with

These districts appear alongside Frederick County in the same ZIP Code areas: Carroll County, Washington County, Montgomery County and Howard 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.

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 11 of the 35 ZIP Code areas Frederick 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.
