The Série D is the fourth tier of professional football in Brazil, established in 2014. It serves as a platform for clubs that are not part of the higher divisions, allowing them to compete for promotion to the Série C. The league features teams from various regions, promoting local talent and fostering community support. The competition format includes a group stage followed by knockout rounds, culminating in a final phase where the top teams earn promotion. The CBF (Brazilian Football Confederation) oversees the league, ensuring that clubs adhere to regulations and standards for fair play and organization.
