Juricode

A Juricode is the complete stack of jurisdictions that govern a single point on the map — from the federal government down to your local school district.

Enter any U.S. address and we geocode it to precise coordinates, then query every jurisdiction boundary in our database to find the ones that contain that point. The result is a layered view of who governs here.

1

Address

Any U.S. street address — a home, office, landmark.

2

Geocode

Convert to precise latitude/longitude coordinates.

3

Spatial Query

PostGIS ST_Contains against every jurisdiction boundary (TIGER shapefiles).

4

Juricode

The full governance stack — federal, state, county, congressional, school district, city.

Data source

Boundaries come from the U.S. Census Bureau TIGER/Line shapefiles (2025 vintage). Imported as PostGIS geometries and indexed with GIST for fast spatial queries.

Completeness

Full coverage for states, counties, and congressional districts. Place-level coverage is expanding — school districts and county subdivisions are being added by state.
