Azerbaijan did not qualify for the tournament and the AFFA said fans from countries taking part will be allowed to attend matches provided the requirements for a visa and COVID-19 mitigation are met.
European soccer governing body UEFA had set a Wednesday deadline for the 12 host cities to submit their plans for fan capacity at the rescheduled June-July tournament.
Hungary did not make their submission to UEFA public but information on ticketing plans are set to be announced next week.
“We want, if the epidemiological situation allows, as many fans as possible to watch the matches in the Puskas Arena, with maximum compliance with safety and epidemiological regulations,” a Hungarian FA spokesman told Nemzeti Sport.
Baku will be hosting three group games and one quarter-final while Budapest stages three group games and one last-16 game.
On Wednesday, Dublin and Bilbao said they were unable to commit to at least some fans being able to attend games while Italy were unable to confirm their plans by the deadline.
