The draw for the third round was held on 17 April at the CBF headquarters in Rio de Janeiro. The 32 teams, qualified from the previous round, were placed into two pots, seeded by their national ranking, and then drawn into 16 ties. A second draw determined the home and away teams for each leg.^[1] Each team's CBF ranking is shown in parentheses.
