Thirteen spots have been confirmed and just seven places remain.
Eight elite women's surfers' tickets have been locked in through the WSL Championship Tour.
The final spots were confirmed in Hawaii as Carissa Moore became the first American female to qualify for surfing's Olympic debut while clinching her fourth surfing world title.
The second and final U.S. women's spot went to 17-year old Caroline Marks, while Silvana Lima of Brazil and Brisa Hennesy of Costa Rica took the last two places on offer through the WSL.
These four surfers join an already impressive list of women who have provisionally qualified through the 2019 WSL Championship Tour, including Australia's Stephanie Gilmore and Sally Fitzgibbons, Brazil's Tatiana Weston-Webb, and France's Johanne Defay.
Daniella Rosas will represent Peru after earning qualification through the Pan American Games in Lima, Peru, in July.
And the 2019 ISA World Surfing Games saw Japan’s Shino Matsuda, South Africa’s Bianca Buitendag, New Zealand’s Ella Williams, and Israel’s Anat Lelior earn their places too.
The remaining seven women's spots will be allocated at the 2020 ISA World Surfing Games in May, at a location to be determined.
