Given an address or latitude/longitude coordinate pair, Geocodio can return information about the location's state legislative districts. You can upload a spreadsheet, or use our API.
For states with bicameral districts:
For state with a unicameral legislature, such as Nebraska, data will be returned under a "Senate" header.
We do not currently return data for multi-member districts, but this is on our roadmap.
We do not return state legislator contact information. (This is not on our current roadmap.)
Many state legislative districts will be redistricted based on changes from the 2020 Census.
Redistricting: This is a fluid situation and we are monitoring all states for approved and revised maps. See our redistricting 2020 page for more information on updated states and how to add the new districts.
OCD-IDs: Open Civic Data Division Identifiers (OCD-IDs) are a new data inclusion and are automatically returned when adding upcoming districts.
If you would prefer to programmatically integrate state legislative district data, you can see our API documentation for state legislative district appends here.
Requests are billed as geocode + state legislative info (i.e., two lookups). For example, if you have 100 addresses that you want state legislative districts for, that would count as 200 lookups.
You can calculate how much this will cost you and how long it will take here.
