Periodically, the Supervisor of Elections will send address confirmation notices to voters when the post office has indicated that these voters have moved outside the supervisor's county or left a forwarding address. All voters who have been mailed an address confirmation notice and who do not return the form within 30 days will be placed on the inactive voter registration list. Voters on the inactive list can be reinstated by updating their voter registration, appearing to vote, or requesting an absentee ballot, providing their status has not changed. However, after two general elections from the date the notice was sent, all inactive voters who show no activity will be removed from the registration records and must register again in order to vote.
