The competition started its new season on January 27, 1991 and ended on May 26, 1991. The championship was organized by the national association CBF . At the end of the season, Paysandu SC celebrated the championship.
In contrast to the previous year, the league was expanded from 24 to 64 participants. The competition was held in a group phase and a knockout round from the round of 16 to the final. All matches were played back and forth. Both finalists qualified for the first division in 1992 .
In the first round, the 64 participants competed against each other in eight groups of eight clubs each. The top two clubs in each group advanced to the second round. When putting together the groups, the regional origin was taken into account in order to minimize costs for smaller clubs.

Return leg
After Paysandu's second goal in the 81st minute, several Guarani players protested so violently that six of them were red carded. Then the game was declared over.
The table only served to determine the placement of the individual teams in the season. At times it was used by the association to determine an eternal ranking list. It is made up of all the games played. In the sorting, reaching the respective final phase has priority over the points scored.
