Taffarel made his debut for Brazil on 7 July 1988 in the Australia Bicentenary Gold Cup, playing all four games and conceding two goals as his team won the tournament. He was also in goal for the following year's Copa América, which Brazil also won (during his ten-year international career, he appeared in five editions of the latter tournament, winning the title for a second time in 1997, and collecting runners-up medals in 1991 and 1995). At the 1988 Summer Olympics in Seoul, he won a silver medal, saving three penalties against West Germany in the semi-finals of the tournament: one in regulation time, and two in Brazil's successful shoot-out. He was also a member of the Brazilian team that took part at the 1990 FIFA World Cup in Italy, where Brazil were eliminated in the round of 16 following a 1–0 defeat to rivals and defending champions Argentina, with Taffarel conceding only two goals in total throughout the tournament.
