NationBuilder gathers voter files from across the country. We standardize the data and regularly update the information to include current voter registration and recent elections. We began this process as a resource to help NationBuilder customers run campaigns.

Obtaining the data is always free when used in NationBuilder. You will also be subscribed to automatic data updates at no cost. Importing a voter file increases the number of people stored in a nation, usually increasing the cost. NationBuilder pricing varies based on the number of people in your database and the plan selected. We can help you determine the most cost effective way to request voter data. For example, you may want to request one political party during your primary election.
