IRELAND will play Bosnia and Herzegovina and Hungary in the warm-up phase before Euro 2012 in Poland and Ukraine.
The Bosnia and Herzegovina game will be at Aviva Stadium on May 26. Ireland then depart for a week of training at Montecatini, near Florence.
They will then travel to Hungary for a match in Budapest on June 4.
Ireland is already scheduled to play the Czech Republic, on 29 February.
FAI CEO John Delaney also confirmed that the FAI had made representations to tournament organisers in a bid to secure extra tickets for supporters.
He expects 20-25,000 Irish supporters to travel.
Speaking to Morning Ireland, he added: "I am hopeful that we might get some extra tickets as we get nearer to the Euros. We have made representations. We have got 6,000 tickets per game, they'll all go.
"We are going to try to secure some extra tickets for the supporters because it is in our interest and everybody's interest to get as many Irish people into those three games as possible to encourage the team and get behind the team."
He also said that tickets would be available at low prices for the Czech Republic fixture. Adult stand tickets will be available from €20, while general admission tickets for children are €10.
"We want to continue with the great atmosphere that was there after the Estonia match and during the Estonia match.
"I think everybody is reducing their prices. The GAA have done it, the IRFU have done it and we have done it. This is a game at the end of February, after Christmas which makes it important because people have spent money during Christmas."
