Pompey are hoping for season ticket sales of more than 10,500.
Chairman Iain McInnes is confident of going beyond that figure.
Currently a staggering 10,152 have been sold ahead of the League Two campaign.
The early bird option has finished.
And with just two weeks before the August 3 kick off, sales are expected to slow.
However, the Fratton faithful are continuing to snap them up as the feel-good factor continues.
McInnes believes 10,500 represents a realistic target.
He said: ‘It’s absolutely incredible how many we have sold but not surprising because of the fans we’ve got.
‘The biggest asset this football club has by a mile – and it is a fixed asset from a business point of view – is the fans.
‘It is a fantastic achievement.
‘Am I surprised? Not completely.
‘Am I delighted? Absolutely. Do I think it will go higher? History says it will.
‘If they get to 10,500 and build from there then this is a great start.
‘The supporters have done everything they said they were going to do.
‘You can’t get a better deal than that.
‘In the plan, originally, we were looking at around what we did last year, which was 7,250 in addition to half-season tickets.
‘I always thought if we beat that number it would be a great result.
‘If we can get to 10,500 and another 6,000 a week come on top of that to give us an average gate of 16,500, it will be fantastic.
‘And I reckon with bits and pieces we can get to 10,500.’
Meanwhile, Pompey season ticket cards will be sent out next week.
Or they can be collected from the ticket office until 5pm tomorrow.
