The following categories of persons may apply for registration as postal voters: members of the Gardai, persons living at home who are unable to go to a polling station to vote because of a physical illness or disability; and persons whose occupations are likely to prevent them from voting at their local polling station on election day, including full-time students registered at home who are living elsewhere while attending an educational institution in the State. Additionally, an elector unable to vote at their polling station due to their detention in a prison pursuant to an order of a court may apply for registration as a postal voter. In addition wholetime members of the Defence Forces and Irish Diplomats posted abroad and their spouses are registered as postal voters.
To be included on the postal voters list applications must be received by at least 22 days before polling day (not including Sundays, Good Friday or Public Holidays).
