Mino Raiola's initial ban, issued by the Italian Football Association (FIGC), has been given global status by FIFA, the world game's governing body.
Agent Mino Raiola has had his ban extended to "a worldwide effect" by FIFA.
Raiola given three-month ban by Italian FA on Wednesday
Raiola, who represents the likes of Paul Pogba, Matthijs de Ligt and Zlatan Ibrahimovic, was given a three-month suspension on Wednesday by the Italian Football Association (FIGC), although it did not provide any specific reasoning.
Raiola moved to reassure his clients that potential business in the coming transfer window would not be affected as the ban was restricted to Italian territory, while he made it clear he would contest the FIGC's decision.
But FIFA announced on Friday that it has extended the suspension to a global scale.
"The Chairman of the FIFA Disciplinary Committee has today decided to extend the sanctions imposed by the Italian Football Association (FIGC) on the intermediaries Carmine and Vincenzo Raiola to have worldwide effect. Carmine Raiola is suspended for a period of three months and Vincenzo Raiola for a period of two months," FIFA said.
"The decision of the FIFA Disciplinary Committee was notified today and takes immediate effect."

Raiola, one of the world's most high-profile and influential agents, claimed via Twitter on Thursday that the FIGC's sanction was "a sentence dominated by political willing, without taking into the right consideration of law."
He added that it was "a sentence based on false grounds and lies".
Could have repercussions for moves involving Pogba, De Ligt...
The latest news could have repercussions for any of Raiola's clients who had been relying on him to broker moves before next season.
Manchester United star Pogba has been heavily linked with Real Madrid for many months, while Ajax captain De Ligt has been tipped to follow team-mate Frenkie de Jong and join Barcelona.
