Over 240,000 tickets for the singer's comeback special this summer sold out in 90 minutes on Thursday.
It is estimated around 10,000 people all over Ireland queued up for tickets for the much anticipated concerts.
The country music legend is due to perform at Croke Park on 25, 26 and 27 July.
The singer initially announced his comeback for two dates at the Dublin venue, but due to high demand for tickets a third date was added.
Speaking about the huge tickets sales, manager Bob Doyle said: "We're thrilled. (Promoters) Peter Aiken, his team and Ticketmaster have done an amazing job."
"In 52 years of business this is the fastest selling concert Aiken Promotions have ever been involved in," added Peter Aiken.
After being in retirement for a decade, the If Tomorrow Never Comes singer is putting on three special performances in Ireland ahead of a world tour.
Announcing the special concerts earlier this month, Brooks said: "Before we go back on tour in the Fall of 2014, I want to challenge myself, the band, and crew.
"In '97, we were lucky enough to play Croke Park, the stadium was under construction. (There was over) 130,000 of some of the greatest fans in the world.
"I was quoted then as saying "When this stadium is finished, I would love to come back and try to fill it again...this time to the brink."...and we're back to do just that."
