    The Sonoma County Registrar of Voters wants to help voters who may have been impacted by the wildfires understand how to update Voter Registration.  The residence address we have on file determines the contests for which you are eligible to vote.  The mailing address we have on file determines where we mail voting materials, such as Voter Information Guides and, if registered to Vote by Mail, official ballots.  Voters may be legally registered in only one county.
