Rhode Island General Laws Title 17. Elections § 17-9.1-19. Single registration

(a) Nothing in this chapter shall be construed to require any voter to reregister if he or she is already registered in the city or town in which the voter has his or her residence, as defined in § 17-1-3.1. A voter shall have no more than one voter registration. Any voter who is registered more than once shall be deemed to have authorized the cancellation of all registrations other than the most recent, provided that nothing in this section shall be taken to validate any registration which is not a city or town where the voter has his or her residence.

(b) The local board of canvassers of each city or town shall review their voter registration files on a quarterly basis in accordance with regulations adopted by the secretary of state for the purpose of removing duplicate voter registrations in the central voter registration system for any voter registered in their city or town.
