CONMEBOL has issued a temporary order after the death of a young fan at the Brazilian club's Copa Libertadores game with San Jose.
The ban will remain in place until the South American governing body makes a final ruling on the matter.
During Corinthians' first game in its defense of the Libertadores trophy against San Jose in Oruro, a firecracker was launched into San Jose fans from the away section, killing a Bolivian supporter. The object penetrated the young fan's eye and he died before reaching hospital.
Fans of the World Club Cup winners will be denied admission to next Wednesday's home tie against Colombian side Millonarios and subsequent home matches against Tijuana and San Jose. A total of 83,500 fans were hoping to attend the three games in Sao Paulo's Pacaembu stadium.
According to local reports, 12 supporters have also been charged with homicide after events at San Jose's Jesus Bermudez stadium.
