The 2031 Women's World Cup will expand to 48 teams, with the 16-team increase announced among other landmark decisions by the FIFA Council on Friday.
The decision to expand the World Cup aims to "broaden representation, offering more nations and players access to elite competition and accelerating investment in women's football worldwide," according to the FIFA release.
"The FIFA Women's World Cup 2023, the first in which teams from all confederations won at least one game and teams from five confederations reached the knockout stage, among many other records, set a new standard for global competitiveness," said FIFA President Gianni Infantino.
"This decision ensures we are maintaining the momentum in terms of growing women’s football globally."
The expanded 2031 World Cup, hosted by the US, will adopt a 12-group format, increasing the total number of matches from 64 to 104 while extending the competition for an additional week.
The World Cup expansion announcement comes on the heels of last month's increased Olympic tournament news, with the IOC boosting the women's soccer field to 16 teams at the 2028 LA Games.
The decision also puts the women's competition in line with the men's World Cup, which will feature FIFA's first 48-team tournament in 2026.

FIFA approves Afghan women's refugee team
In the same Friday announcement, the FIFA Council also approved the creation of an Afghanistan women's refugee team, which would provide evacuated Afghan women players the ability to compete on an officially recognized FIFA team.
While FIFA requires that national federations sponsor teams, the Afghan Football Federation ceased acknowledging its women's team once the Taliban-controlled government banned women's sports.
Originally formed by the country's Olympic Committee in 2007, the Afghanistan women's national team has not played a FIFA-recognized match since 2018, and most of its athletes fled the country amidst the Taliban's second takeover in 2021.
Since then, players have petitioned FIFA for the opportunity to compete. Their efforts earned a one-year trial phase from the governing body on Friday, though the success of the program could see it expanded to refugees from other nations in the future.
"We are happy that FIFA has created a pathway for Afghan players to finally return to the field," team founder and former captain Khalida Popal told CNN on Friday, adding that the squad "remain[s] hopeful FIFA can amend its statutes to provide official recognition for our players as the Afghanistan Women's National Team."
Popal — who helped hundreds of Afghans, including the team, escape the Taliban — previously said the team "could show the world that Afghan women and girls belong in sport, in school and everywhere in society — and we will not be defeated."
