The new scheme will see €230 a week paid for two weeks
An awareness campaign has been launched to highlight new paternity leave benefits.
It is urging prospective parents to register, and also explains how to apply.
Paternity benefit will be paid at a rate of €230 a week for two weeks - to both employees and the self-employed.
It is available from September 1st.
Parents are being reminded that they need a Public Service Card in order to apply - just over two million cards have been issued to date.
And if they are an employee, they need to give four weeks' notice to their employer to qualify for the leave.
The campaign features a digital video, explaining the scheme and how to apply - while digital adverts will be carried on a range of websites.
Speaking at the campaign launch, Social Protection Minister Leo Varadkar said: "We want to make sure that fathers and mothers-to-be across Ireland know that they can start claiming for two weeks of paternity benefit from September 1st."
"That's why my department is launching a publicity campaign this week, to make sure that eligible parents apply for this ground-breaking measure, which provides a guaranteed income of €230 a week for two weeks."
"We also want to ensure that fathers know how to apply. It's really simple, but you need to take a few straightforward steps."
People are eligible for paternity benefit when they take their statutory two weeks of paternity leave and fulfil the PRSI requirements.
Paternity leave can be taken at any time within the first 26 weeks of the child's life, or following adoption.
