How to Find Your School District by Address (and Confirm the Boundary)
Public school assignments in the US are determined by district boundaries — geographic lines drawn by school boards or state agencies. Two houses across the street can attend different schools, sometimes paying very different per-pupil-funded taxes.

How boundaries are drawn
Most US public school districts are coterminous with a city, township, or county. But many states (Texas, California, Pennsylvania) have hundreds of independent districts whose boundaries don't follow city limits at all.
Within a district, individual school 'attendance zones' (which elementary, middle, high you go to) are drawn by the local board. These can change year-to-year as enrollment shifts.
Why the same street splits
Geographic features (rivers, highways, rail lines) often serve as boundaries. So do historic political boundaries that no longer match modern roads. So do 'magnet' or 'choice' carve-outs that cross district lines for specialty programs.
If your address is near a boundary, the district's address-lookup tool is the source of truth, not the apparent school in the next block.
Where the data comes from
The US Department of Education's National Center for Education Statistics (NCES) publishes the Common Core of Data (CCD) annually with: district boundary shapefiles, per-school enrollment, demographics, federal-funding eligibility, and student-teacher ratios.
zipradar overlays the NCES shapefile against your ZIP centroid to show the assigned district. For block-level certainty, use the district's own enrollment portal.
What zipradar shows
The assigned public school district for your ZIP centroid, the per-school enrollment + student-teacher ratio for the schools in that district, and a deep-link to GreatSchools.org for parent-rating data (we don't aggregate ratings ourselves; we link).
Coverage: all US public schools and districts. Private and charter coverage is partial as state reporting varies.
