Need to add Congressional districts or Senator and Representative contact information to addresses or latitude/longitude coordinates in bulk? You're in the right place.
This article shows you how to add Congressional districts using Geocodio. The Congressional district data returned includes Congressional district number, Congress number, and Congress years, with the option to append legislator data. You can use our API to integrate it into a website, or upload Excel, CSV, and TSV files.
If you just need the Congressional districts and Senator/Representative contact information for one address, you can use the tool below. Just check the box next to ‘Congressional Districts’, then click ‘show results.’
Addresses do not need to be complete in order for you to be able to add Congressional districts.
The following address combinations are acceptable:
Next, create an API key. Creating an account and an API key is free. You can create an API key here.
Results are billed as geocode + Congressional district info (i.e., two lookups). For example, if you have 100 addresses that you want school districts for, that would count as 200 lookups. You can calculate how much this will cost you here.
There are (official libraries)[https://www.geocod.io/docs/#libraries] for node.JS and PHP (including Laravel features). There are also (community-created libraries)[https://www.geocod.io/docs/#libraries] for R, Python, Ruby, Clojure, Perl, Go, and C#.
Adding Congressional districts works for both forward geocoding (address to coordinates) and reverse geocoding (coordinates to addresses) endpoints. You just add fields=cd to your request. (You can see more about integrating the API here.)[https://www.geocod.io/docs/#congressional-districts]

“In elections, we can’t have even a 5% tolerance for error. Geocodio gives us the accuracy we need to give people the correct information about the election and remind them to vote.”
