And Royal Ascot, which runs from 15-19 June, will be permitted to host 12,000 spectators each day.
That is more than double what the race meeting had been expecting.
England’s first two group games in Euro 2020 will also be part of the next stage of the pilot project, as has already been reported, with 20,000 fans permitted at Wembley.
Current government guidance is that up to 10,000 spectators, but no more than 25% of capacity, are allowed in stadiums while for non-seated outdoor venues like racecourses there is a current cap of 4,000.
Edgbaston, the home of Warwickshire, has a capacity of 25,000 while Ascot can hold up to 70,000 people.
All ticket holders for Edgbaston must be 16 or over and will need to present a negative NHS lateral flow test taken within the preceding 24 hours.
“Having crowds back into cricket grounds is so important for the game and for our fans too,” said England and Wales Cricket Board chief executive Tom Harrison.
“The last 15 months have shown just how big a role cricket plays in many people’s lives, and we cannot wait to welcome a growing number of fans back to our stadia over the coming months.”
