Pompey have sold more than 10,000 season tickets for next season.
The figure was topped yesterday as fans took advantage of the last day of the club’s early bird reduced prices offer.
It represents a huge show of support after Pompey became the biggest fans-owned club in the country.
Despite relegation to League Two, supporters have flocked to secure their places at Fratton Park next season, with the Fratton End now almost sold out.
Last summer, 7,250 season tickets were sold before the start of the season.
This year’s tally is already more than twice the average home attendance for League Two clubs.
Season tickets are still available for Pompey fans wishing to secure a seat for home games next season.
