The tournament follows a similar format to the men’s event, with the 53 participating teams divided into three leagues.
The four League A group winners will meet in the semi-finals, which are followed by a third-place play-off and the final.
In a change from the inaugural edition of the Nations League, these knockout ties will be played over two legs.
The teams who finish fourth in each League A group will be relegated, with the League B group winners going up to replace them.
In League B, each fourth-placed team will be relegated, as will the two lowest-ranked third-placed teams. Each of League C’s six group winners will be promoted.
The Nations League will also affect qualification for the 2027 Women’s World Cup in Brazil.
The top two teams in each group remain in League A for the European qualifiers for for the 2027 FIFA Women’s World Cup.
The four third-placed teams from League A will play against the second-placed teams from League B, with the winner playing in League A for the World Cup qualifying phase.
In League B, the two best third-placed teams play off against the two best-ranked second-placed teams of League C, with the winners playing in League B for the World Cup qualifying phase.
