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.)
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.
