Voter List Maintenance, commonly referred to as four year maintenance is outlined in Wisconsin Statutes §§6.50 (1) and (2) requires the Commission, in June following a general election, to mail notices to all voters who have been registered to vote for the past four years but have not voted. The notice indicates that voters’ registrations will be deactivated unless they request continuation of their registration within 30 days.
If the notice is returned as undeliverable or if the voter does not respond within 30 days, the Commission deactivates the voter’s registration in the statewide voter registration system. Voters who are deactivated do not appear on the poll list on Election Day and must reregister to vote. Pursuant to Wis. Stats. §6.50 (2r), the Commission must post voter record maintenance statistics on the agency website.
