The most divided ZIP Code area in Colorado
ZIP Code area 80808 is the most divided in Colorado: 6 districts reach into its 2,706 homes, led for the early grades by Calhan School District RJ-1 and Ellicott School District 22. No single name describes this postal code, and no lookup that gives one is telling the whole truth about it.
Each percentage here is a share of the 2,706 homes counted in ZIP Code 80808, not the chance that any one address is in that district. Enrollment follows the street: two houses on opposite sides of the same road can be in different districts, and only the district office can say which.
Every track below is 35 cells long and stands for all 2,706 homes counted in ZIP Code 80808, so one cell is 77 homes, rounded to the nearest whole cell. Cells lit solid are the homes one district holds, and the unlit cells are the homes held by the other districts in the same list.
- Calhan School District RJ-11,276 of 2,706 homes47%
- Ellicott School District 22988 of 2,706 homes37%
- Miami-Yoder School District 60-JT209 of 2,706 homes7.7%
- Peyton School District 23-JT124 of 2,706 homes4.6%
- Big Sandy School District 100J66 of 2,706 homes2.4%
- Kiowa School District C-242 of 2,706 homes1.6%
One further district reaches into this area and holds 1 home in it, under half a percent of the homes named at this level.
For grade school, an answer of one district name would be wrong for 1,430 of the 2,706 here.
How much of Colorado a single district name misses
Across the 520 ZIP Code areas in Colorado with homes in them, an answer of one district name misses 229,900 of the 2,491,525 homes they hold — 9.2% of the state. In 251 of those areas the largest district for the early grades holds every home counted; in the other 269 it leaves some out. That is a different count from the 234 areas served by more than one district: it also counts districts under half a percent of the homes and homes in no district, and it does not count a high school district that differs.

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: 234 of the 520 ZIP Code areas in Colorado with a district named for 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.
