Denver County School District 1

Colorado · runs pre-K through grade 12

NCES ID 0803360 · dpsk12.org · (720) 423-3200

Denver County School District 1 covers 344,980 of the homes in 41 ZIP Code areas, but its smallest measured presence is a different thing entirely: in ZIP Code area 80226 it holds 90 of 14,349 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 4 further ZIP Code areas, the least of them no homes at all in 80264.

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

At 2,254 homes to the square mile this is city territory, and district lines in a city follow streets. Denver County School District 1 covers 153 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 80211 this district holds 100% of the homes; in 80294 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.

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 18 of the 41 ZIP Code areas Denver County School District 1 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.
