PPS numbers will be used to verify voters' identities, under plans being put forward to modernise electoral registration.
Following a public consultation process earlier this year, the Government has said the existing processes will be changed as part of moves towards a rolling, continuously updated electoral register.
Under the proposals, the existing forms and voter registration process will be simplified.
There will be an optional online registration system, although the paper forms will continue to be available for those who want them.
The Government says there would also be 'limited' data sharing between public bodies and local authorities "to maintain accuracy and comprehensiveness" of the register.
Other proposed reforms include improved registration measures for people with no fixed address; pre-registration for 16 and 17 year olds; and a system of 'anonymous registration' for anyone whose safety may be at risk.
Planning and Local Government Minister Eoghan Murphy said: "These changes, which represent the most significant modernisation of the electoral registration process since 1918, will allow for more responsive engagement with the public; more efficient administration and crucially, will protect the integrity of our electoral registration process into the future.”
Explaining the results of the public consultation, Minister of State for Electoral Reform John Paul Phelan, noted: "Whilst people welcomed the idea of online registration, respondents felt that technical security, stability and resilience are critical issues.
"We will be mindful of these during implementation of changes so that public confidence in our electoral registration process is maintained.”
He added: "We will run information campaigns at key stages so the public is made aware of all changes well in advance, so people know how they can register or change their registration details, and how reforms will or will not affect them."
An outline of the proposed legislation will now be drawn up, before being brought to the Government for approval early in the new year.
