The Scottish Government has approved an SFA proposal to permit fans to attend Euro 2020 clashes at Hampden.
A statement from the governing body confirmed a submission was made to UEFA on Wednesday for the return of 12,000 spectators to the four matches being staged in Glasgow.
It follows First Minister Nicola Sturgeon insisting she was "very, very hopeful" the national stadium could open its gates again this summer.
And Record Sport revealed on Tuesday night the SFA were proposing between 10,000-15,000 punters could attend Scotland's tournament curtain-raise against Czech Republic on June 14.
Scottish football bosses have now revealed Holyrood officials and public health advisers have signed off on 25 per cent capacity.
The statement said: "The Scottish FA and Glasgow Life (on behalf of Glasgow City Council) have been working on a range of planning scenarios for hosting the four UEFA EURO 2020 matches in Glasgow in response to the ongoing coronavirus pandemic, both in terms of allowing spectators in the stadium and the creation of a Fan Zone in the city for the duration of the tournament.
"Following extensive consultation with the Scottish Government and public health advisers, the Local Organising Structure can confirm that it has submitted details of its preferred option for admitting spectators to the stadium to meet today’s (7 April) UEFA deadline.
"We are delighted that the Scottish Government has given approval to allow spectators up to 25% of the stadium capacity (approximately 12,000 - based on the UEFA EURO 2020 venue overlay and seating configuration) for each of the four games to be staged at Hampden Park.
"Naturally, this will be subject to continued progress with reducing the prevalence of the virus and the roll-out of the vaccination programme.
"A decision on the Fan Zone in the city will be made at the end of April.
"On 9 April UEFA will be in contact with all ticket holders advising them on the latest tournament arrangements including ticketing and travel information."
