FIFA says it has received 506,000 online applications for tickets from 140 countries to the 2010 World Cup since they went on sale Feb. 20.
The total doesn't include paper applications made by South African residents.
FIFA said Tuesday that 15 percent of the 3 million tickets will cost $20 -- well below the top price of $900. The low-priced tickets will be available only to those living in South Africa, a nation with high unemployment and poverty.
Tickets will be sold in several phases and are available on FIFA's Web site.
A random draw will be held April 15 at the end of the first phase.
