Remaining tickets for the Paralympics will also be up for grabs on a first-come first-served basis at 1300 on 2 December, organisers Locog say.
Track cycling and wheelchair rugby have sold out, but tickets are available for athletics, wheelchair basketball, swimming and equestrian events.
Tickets range from £10 to £45, while those for children and seniors cost £5.
Some 800,000 Paralympics tickets were allocated to 100,000 people through September's initial public application phase.
Tickets are available on each day of the Paralympics, which run from 29 August to 9 September.
They can be bought online or over the phone on 0844 847 2012. Would-be spectators will have to use a Visa card for any purchase.

The Olympic football tickets are available to anyone who wants to apply on a first-come-first-served basis.
Olympics matches are taking place at Wembley, Hampden Park in Glasgow, Cardiff's Millennium Stadium, Manchester United's Old Trafford, St James' Park in Newcastle and the City of Coventry stadium.
The GB Men's team, who are coached by England under-21 manager Stuart Pearce, kick off at Old Trafford on 26 July 2012, before moving on to Wembley Stadium on 29 July and then the Millennium Stadium on 1 August.
Hope Powell is the coach for the Women's team, whose first game is at the Millennium Stadium on 25 July, with a further fixture in Cardiff on 28 July, before the side play at Wembley on 31 July.
The competition schedule starts with group matches and ends with a knockout phase.
The official draw for the Olympic football tournament will take place on 24 April 2012 at Wembley Stadium.

Paul Deighton, chief executive of London 2012 organiser Locog, said: "Those lucky enough to get hold of one of these remaining tickets will get the chance to witness amazing athletes and sport like never before."
After the December tranche, further tickets will be released in April.
Ticket allocation for the Olympics earlier this year angered thousands of members of the public who were left empty-handed as the opening and closing ceremonies, athletics and cycling sold out.
Many more people applied than got tickets, leading to disappointment and frustration at a system in which applicants were told money would leave their accounts before they were notified which events they had been allocated.
This led to days of limbo before applicants knew whether they had any tickets, and if so, which ones.
Locog says some 3.5m Olympics tickets have now been sold to 850,000 people, and the majority of events are now sold out.
And Locog estimates that up to 1m more tickets will be made available next year as the exact number of seats becomes clearer from contingency, returns and the fitting out of venues.
