Requires states to automatically register eligible U.S. citizens to vote on the day they turn 18 and expands automatic voter registration at motor vehicle and similar government offices. It sets national data-security and privacy rules, bars use of automatically collected registration data for immigration or commercial purposes, creates civil protections for people automatically registered, and funds state implementation through grants administered by the Election Assistance Commission.

Establishes definitions and an NVRA-based automatic-registration pathway, requires states to meet national technical and accessibility standards (with NIST guidance for security), and authorizes $3.0 billion for initial grants (fiscal year 2026) with additional sums as necessary; the law generally takes effect January 1, 2026, with a possible state-level extension to January 1, 2028 if implementation is impracticable.
