FIFA says its disciplinary committee ordered binding verdicts to extend national suspensions.
Former South Korea international Kim Dong-hyun was banned for life, and Choi Sung-kuk got a 5-year ban.
The South Korean investigation involved fixed matches in the K-League and League Cup.
In Croatia, coach Vinko Saka, former NK Medimurje players Mario Darmopil, and goalkeeper Danijel Madaric were banned for life. They helped fix top division matches in the 2009-10 season.
The FIFA bans prohibit playing or working in world football.
