Zurich - Tickets for 2014 World Cup matches in Brazil will go on sale on August 20.
FIFA says the first sales phase will begin when "football fans will have the opportunity to purchase tickets via www.fifa.com."
Ticket prices are scheduled to be confirmed at a July 1 news conference, the day after the Confederations Cup final in Rio de Janeiro.
FIFA has previously said it expects around 3.3 million tickets to be available for the 64-match flagship tournament from June 12 - July 13.
The first round of ticket sales should be allocated in a worldwide lottery.
Further tickets will be available after the 32-team lineup is confirmed in November.
The World Cup draw will be conducted on December 6 in Salvador de Bahia.
