Juricode

Every point on the map sits inside 8 to 15 overlapping layers of government — federal, state, county, city, congressional district, school district, and more.

A Juricode is the complete, ordered stack of jurisdictions that govern a single address. Most people can name three of them. Jurisdictional surfaces all of them.

What is a Juricode?

The word "jurisdiction" means the right to exercise authority over a place. When you live at a specific address, multiple governments simultaneously have jurisdiction over you — each with different powers, different elected officials, and different rules.

A Juricode is the complete, ordered list of those jurisdictions for a single point on earth. Enter an address, and we geocode it to a precise latitude/longitude, then query our database of Census TIGER boundaries to find every jurisdiction that contains that point.

The result is a structured civic fingerprint: the layers of government that touch your address, from the federal government down to your school district.

How it works

1

Address

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

2

Geocode

Converted to precise latitude and longitude coordinates.

3

Juricode

A spatial query finds every jurisdiction boundary that contains that point — returning the ordered governance stack, from federal to neighborhood.

Example: 300 Hemlock Ave, Vacaville, CA

A single residential address has all of these governance layers.

federal United States of America
state California
congressional district CA-4 Congressional District
