(Salem, OR) -- Oregon has updated its online voter registration system to allow eligible residents to register using the last four digits of their Social Security number and a verified signature. The change takes effect Wednesday under a law passed in 2022 and signed by Tina Kotek, expanding access for voters without an Oregon driver's license or state ID. State elections officials say county offices will continue to verify all registrations, while some Republican lawmakers have raised concerns about election security under the new system.
