The Irish FA has confirmed that Northern Ireland fans will be allowed to apply for two tickets to the Euro 2016 finals in France.
Supporters who regularly attended games during the Euro qualifying campaign will be rewarded for their loyalty by being given priority.
The decision follows discussions this week between the IFA and UEFA.
Priority will be given to block bookers who renewed tickets after the 2014 World Cup campaign and those who bought tickets for Euro 2016 qualifiers.
The IFA also said that the success of applications from fans who apply for two tickets will be affected by the “purchasing behaviour” of the second named applicant.
“Supporters who apply for one ticket will have a level of priority based on their own purchases, while fans who apply for two tickets will have a shared priority allocation,” the Association said in a statement.
“For example, if a block booker who applies with another block booker then both remain at the level of priority that they would have had if they had been applying as individuals.
“However, if a block booker applies with a supporter who hasn’t attended any Northern Ireland games in recent years, then the priority points will be divided between both.
“Due to UEFA rules, if the application system had been limited to one, under 18s would not have been able to purchase tickets due to the application being a legal agreement. This would have meant that junior campaign card holders would have been excluded from the process. We currently have over 500 junior campaign card holders.
“This way forward means that supporters can choose to apply for more than one ticket, it means that block bookers under 18 are not penalised, but also significantly it means that those who have supported Northern Ireland throughout the qualifying campaign are given priority to apply.
