People are being reminded to check the register to ensure they are registered to vote in the upcoming Presidential Election.
With just three candidates on the ballot, it is the smallest field in a presidential election since 1990.
The independent electoral commission, An Coimisiún Toghcháin, say that there remains a large number of people who are not registered to vote.
Its Chief Executive Art O'Leary has appealed to young people, in particular, to register, pointing out that there are 60,000 people who have turned 18 since last year's general election.
This would be their first opportunity to vote in an election, he said, adding that it takes three minutes to register.
"Your vote is your voice, and if you don't vote, you allow other people to speak for you and you would never allow that to happen in any other part of your life.
"We are encouraging people now that the election is just over four weeks away, that people should make a plan.
"If you know that you're going to be away with work, then you can apply for a postal vote."
Those who are away for work must have their postal vote form stamped by their employer.
He added that those who cannot attend their local polling station on 24 October, such as those with disabilities or students who attend courses away from home, can also apply for a postal vote.
The deadline to register for a postal vote is Monday, 29 September.
The deadline to register and update your details for in-person voting is Tuesday, 7 October.
Voting in the election takes place on Friday, 24 October. The counting of votes will begin on the morning of Saturday, 25 October.
