England fans have made the third-highest number of ticket applications
England supporters are urging their fellow fans to snap up the country's 6,000 unsold tickets for the World Cup finals this summer.
The tickets returned from England's allocation of 29,000 will go back on public sale through Fifa on 9 February.
LondonEnglandFans, a supporters group, wants more England supporters to get behind the team in South Africa.
"This should now be the opportunity to sell the World Cup all over again," said the group's Mark Perryman.
"We want those stands supporting England to be full, and with tickets available South Africa will be the trip of a lifetime.
"We want to ensure any England fan with the means to get there doesn't miss out."
Perryman has organised a meeting on Thursday with World Cup officials, representatives from the Foreign Office and the Football Association and Harpreet Grewal, the head of Englandfans - the official England supporters' club - to help boost sales among their countrymen.
Despite the returns, England supporters have made the third-highest number of ticket applications for this year's World Cup, behind South Africa and USA fans.
England's opening match against the USA on 12 June in Rustenberg is expected to be one of the competition's most popular games.
Supporters of both nations have each been given 12% of the match tickets - about 4,100 seats.
England follow the USA match with fixtures against Algeria in Cape Town on 18 June and Slovenia in Port Elizabeth five days later.
