How to Add Congressional Districts to a Spreadsheet of Latitude/Longitude Coordinates

1. Organize the GPS coordinates you want to add Congressional district info to in a spreadsheet

The first step will be to organize the latitude/longitude coordinates into a spreadsheet. Your spreadsheet will need to have headers. Latitude/longitude can all be in one column combined, or separated, as shown below, as long as it is consistent for the entire spreadsheet.

You can also download an example spreadsheet here. The addresses can be missing information as long as they are all consistently formatted. For example, you can have street + zip for some addresses and street + city + state for others.

2. Upload the spreadsheet of addresses to Geocodio to add Congressional district data

Once your spreadsheet is organized, you can upload it directly to Geocodio. After confirming the columns and seeing a preview of the file on a map, you will be presented with options to append data. You will want to check the box that says “Congressional Districts”, with the option to include Senate and Representative info. Counties are included by default with geocoding.

Results are billed as geocode + Congressional district info (i.e., two lookups). For example, if you have 100 addresses that you want Congressional districts for, that would count as 200 lookups. You can calculate how much this will cost you and how long it will take here.

3. Download your completed spreadsheet with Congressional district information added

You will receive an email when your spreadsheet is done processing -- no need to stay on the page.
