When tickets for the FA Vase final went on sale Monday morning, Hereford's allocation, shown in orange, was around 6,600.
But this afternoon, the club posted an updated seating plan.
Hereford's allocation has more than doubled in the 4 days tickets have been on sale. There is still 2 months until the game.
Over 8,400 tickets have now been sold, well exceeding the initial allocation. Last year's final between Glossop North End and North Shields was watched by 9,674. The Robins won the game 2-1 (AET).
Unlike last year, both finals, the Vase (12:15pm ko) and Trophy (4:15pm ko) will be broadcast live on BT Sport. Only highlights of the Vase were shown last year.
Meanwhile, there is a guide to buying Wembley tickets on the OS, which can be viewed here (link).
Edit 4pm: The FA told one fan on the phone that they have now sold 8,992 to Hereford supporters.
