The demand has reached record levels just 15 days after the start of the random selection draw ticketing phase, which remains open until January 13.
"We have six to seven million tickets on sale. In 15 days we received 150 million ticket requests," FIFA president Gianni Infantino said at the World Sports Summit in Dubai on Monday.
"So 10 million ticket requests every single day. It shows how powerful the World Cup is.
"In the almost 100 years of the World Cup, FIFA has sold 44 million tickets in total. So, in two weeks we could have filled 300 years of World Cups. Imagine that. This is absolutely crazy."
The 48-team World Cup is taking place across 16 host cities in the United States, Mexico and Canada from June 11 to July 19. The cost of tickets has faced widespread criticism. prompting FIFA to introduce a lower price band for some supporters.
Australia's opening match in Group D is against a play-off winner in Vancouver on June 14. The Socceroos then take on the United States on June 19 and Paraguay seven days later.
Fans from the United States have made the highest number of ticket requests, followed by those from Germany and the United Kingdom, from where England and Scotland have qualified, while Wales and Northern Ireland are in the play-offs.
"This overwhelming response from passionate fans is a true representation of how our game is loved globally. We are going to make history in North America when we bring the world together like never before in a celebration of unity and the best of football," Infantino said.
Following the closing of the current ticket request phase, a draw will take place that gives all fans an equal chance of success. Those who are unsuccessful will have the opportunity to secure their seats during the subsequent sales phases as additional tickets are made available.
