Reix, who had a career-high Women’s Tennis Association (WTA) ranking of 204, will not be able to play in, coach at or attend any event authorised or sanctioned by the governing bodies of tennis until 29 January 2027.
She was also fined $30,000 (£24,786/€27,934) as part of the ruling.
Reix was found guilty of six breaches of the Tennis Anti-Corruption Programme (TACP) rules.
These included two breaches of D.1.b, where no covered person shall solicit or facilitate any other person to wager on the outcome or any other aspect of any event or any other tennis competition.
Reix was also found to have twice breached D.1.d, which relates to contriving or attempting to contrive the outcome or any other aspect of an event.
The ITIA also noted one breach of D.1.f, which covers soliciting or accepting money, benefits or consideration with the intention of negatively influencing a player’s best efforts.
In addition, Reix was ruled to have once breached D.2.a.i, which requires players to report any approach to fix matches to the relevant tennis authorities.
The case related to ongoing law enforcement investigations in conjunction with the ITIA in Belgium, which has seen a number of tennis players implicated in match fixing incidents.
