One of the easiest ways of checking if you are registered to vote is to do so on line – go to www.checktheregister.ie, click on “Leinster” as your province, followed by “Dublin City Council” as your local authority, and then enter your details. If you have any problems, the telephone number of the Franchise Section of Dublin City Council is 222 5010.
If you have recently moved, you can notify the Franchise Section of Dublin City Council so that the Supplementary Register can reflect your new address. You have to fill in a Change of Address (RFA 3) form which, after being completed, must be witnessed by a member of the Garda Síochána. The form can then be sent to the Franchise Section, Dublin City Council, Block 4, Floor 1, Civic Offices, Wood Quay, Dublin 8.
All forms are available for downloading at www.checktheregister.ie.
