Brazilians made 70 percent of the requests, followed by Americans, Argentines and Germans.
Each applicant could request for up to four tickets for a maximum of seven of the 64 matches.
FIFA said in a statement that it received applications from 203 countries, with the most sought after matches being the opener in Sao Paulo on June 12 and the final at Maracana Stadium in Rio de Janeiro on July 13. More than 720,000 tickets were requested for the opener and more than 750,000 were made for the final.
Prices for the final range from $440-$990, although Brazilian fans will pay $165 in the cheaper category. Brazilians over the age of 60, local students and members of some social programs will be allowed to pay about $82 for a ticket. Prices for the opener go from $220-$495, with Brazilians paying $80 and discounted tickets costing $40.
All of Brazil's matches were also in high demand.
The most popular host cities were Sao Paulo, Rio and Curitiba. FIFA said there was also "great interest" in the team-specific ticket series, with already qualified Argentina and the Netherlands being the most sought after in that category.
Of the 6,124,682 ticket requests, Brazilians applied for 4,368,029, followed by Americans (374,065), Argentines (266,937), Germans (134,899), Chileans (102,288), English (96,780), Australians (88,082), Japanese (69,806), Colombians (55,379) and Canadians (49,968).
American residents applying for tickets usually include several fans of Mexico and many other countries.
FIFA said it has until Nov. 4 to inform applicants whether they will get the tickets they applied for in the first phase. In the second ticketing stage, applications will be processed in the order they are received.
Nearly 800,000 fans attended the Confederations Cup in Brazil this year, with ticket sales easily surpassing those for the warm-up tournament in South Africa in 2009 and in Germany in 2005.
