The Electronic Registration Information Center (ERIC) is a multistate partnership that uses a sophisticated and secure data-matching tool to improve the accuracy and efficiency of state voter registration systems. Through participation in ERIC, states can compare official data on voters—such as voter registrations and driver's licence information, U.S. Postal Service addresses, and Social Security death records—to keep voter rolls more complete and up to date. ERIC is owned, managed, and funded by participating states and was formed in 2012 with assistance from The Pew Charitable Trusts.
Low registration rates and highly mobile populations can make it difficult to maintain the integrity of voter lists. Approximately 1 in 8 registration records nationwide is inaccurate or out of date, but states that participate in ERIC have increased the accuracy of their voter rolls, improved their election performance across several measures, and reduced their costs. Fifteen states and the District of Columbia are active in ERIC, and more are expected to join in the coming years.
