Football's governing body wants its ruling council to fast-track expansion of the next Women's World Cup to 32 teams.
Fifa has asked council members to approve adding eight more teams within days and without a formal meeting. Agreement would include urgently rebooting the ongoing bid contest to host the 2023 tournament.
Fifa believes the 2019 World Cup, won by the United States in France this month, showed a bigger tournament is commercially possible, and would speed development of the women's game.
President Gianni Infantino set the 32-team target in Paris on July 5, and proposed doubling tournament prize money to $60 million.
"Fifa has a responsibility to ensure its women's competitions not only showcase women's football at the highest level, but also act as a catalyst to grow the game," council members have been told.
