Register to Vote

Voter registration is available at any time. The City of Rockville municipal elections include the option of same-day registration on Election Day. Residents who register through same-day registration will vote provisionally on the same ballot sent to residents who vote by mail. The provisional ballot vote will be counted upon verification of a voter's eligibility. 

Registration remains valid until the voter moves to another jurisdiction.
