In Illinois, registration is required for all elections.
Registration is permanent unless a voter moves or changes name.
Change of address within the county must be reported in writing or in person to the County Clerk at once to maintain the rights of a registered voter. Change of name requires re-registration. Change of address to another county requires re-registration in that county. Two forms of identification showing name are required. Voting registration is closed for a period of 28 days prior to an election.
