Guernsey's Electoral Roll closes on 30 April ahead of the June election.
According to the States of Guernsey, as of 16 April, 24,554 people were registered to vote for the next States.
Reminder cards have been sent to every address where no-one has yet registered.
Registrar-General of Electors, Colette Falla, is encouraging islanders to register online: "We’re seeing an increase in daily registrations and hope to see a big final push.
"We have tried to make the process as quick and easy as possible for people – taking just a couple of minutes if you register online – and have put the information out there far and wide so all eligible islanders are aware.
"It’s important again to remind people that this is a new Electoral Roll so even if you’ve registered on the Roll previously for other elections you must register again if you want to vote in the upcoming General Election.
"While we’d encourage people to register online for speed and ease, paper forms are available if that is the preferred option."
The table below breaks down the total number of people registered in each age group - 10% are aged 60 to 64.
