The Carabao Cup Final between Tottenham and Manchester City this month will be one of the test events used to trial the secure return of fans following the COVID-19 crisis.
Both clubs will be given a portion of the tickets for the game on April 25 at Wembley Stadium.
The remainder will be distributed to Brent residents and NHS employees.
In a statement on Sunday, Tottenham said: “We are conscious that this fixture is less than three weeks away and we will therefore seek to provide you with further information as soon as we have any more updates.”
The second FA Cup semi-final between Leicester City and Southampton on April 18 will also be a pilot event with 4,000 people in attendance, with 21,000 expected to attend the FA Cup Final itself at Wembley on May 15.
“We are delighted to be hosting three test events at Wembley and are confident we can offer a safe environment,” said FA CEO Mark Bullingham.
“This is an important first step towards getting fans back, with the end goal of full stadia – hopefully by the end of the men’s Euros.
“We would like to thank all authorities for their support throughout this process.”
