Paratici was one of 11 individuals banned by the Italian Football Federation (FIGC) in January after Juventus were found guilty of alleged breaches in relation to historical transfer dealings.
The Bianconeri were docked 15 points in Serie A as part of the punishment, with Paratici and Juve denying any wrongdoing and lodging an appeal for the initial sanctions to the Italian Olympic Committee.
Paratici was handed a 30-month ban by the FIGC but continued his role with Spurs due to his punishment only falling under the jurisdiction of Italian football's governing body.
But FIFA confirmed on Wednesday those FIGC sanctions have been extended worldwide, with Tottenham demanding immediate clarity over the bans on their managing director of football Paratici.
"Following media reports today regarding the FIFA Disciplinary Committee decision to extend worldwide the sanction imposed by the FIGC Federal Court of Appeals on Fabio Paratici on 20 January 2023, the club made urgent enquiries to FIFA," a club statement read.
"FIFA has late this afternoon responded to us in writing notifying us today, Wednesday 29 March 2023, that a decision has been made by the FIFA Disciplinary Committee to extend the FIGC sanction worldwide.
"This committee deliberation has been taken with no advance notice to any of the parties involved. We are urgently seeking further clarification from FIFA as to the details of the extension and its variance from the FIGC sanction."
The announcement came just a day after Paratici had addressed the club's media and stated head coach Antonio Conte's dismissal from Spurs was the "right decision for everyone".
Paratici placed his full faith in interim boss Cristian Stellini, who will be in charge until the end of the season, and Spurs sought to clarify the interview took place prior to any knowledge of FIFA's sanctions.
The statement added: "We should like to make clear that when Fabio conducted the interview on club channels yesterday neither he nor the club had any indication of this decision being made by FIFA, based on the fact the FIGC sanction was taken on 20 January 2023 and remains subject to an Appeal on 19 April 2023.
"We shall update on this matter in due course."
