Crowds of 3,000 and 6,000 respectively will be allowed into the Aviva Stadium for Ireland's upcoming rugby internationals against Japan and USA, as fans return to the venue for the first time since February 2020.
The games serve as part of the government's outdoor pilot sporting event programme.
Capacity at the Aviva for the Vodafone Summer Series will be limited to up to 3,000 (5.8% capacity) supporters for the game against Japan on 3 July and 6,000 (12% capacity) supporters for the USA fixture on 10 July.
300 tickets for the Japan game will be allocated to frontline workers.
For the USA encounter on 10 July, 25% of tickets will be allocated to rugby clubs.
It is the first time that fans will be back at Aviva Stadium for a sporting event since Ireland's Six Nations victory over Wales on 8 February 2020.
IRFU CEO Philip Browne welcomed the return of fans and said he hoped they'd be in a position to allow greater numbers attend the autumn internationals.
"We hope that this programme, if successful will put us all in a strong position to welcome back larger numbers of fans to the Aviva Stadium in the Autumn when we will have three international rugby fixtures including games against New Zealand and Argentina."
Both matches are screened live on RTÉ.
