The qualification criteria and slot allocation of the expanded World Championship were approved by the FIVB Board of Administration. Similar to the 2022 World Championship, the number of places in the finals allocated to each of the continental zones was not based on the numbers participating in the qualification round and relative performance of the confederations' teams from the previous edition (for example,
NORCECA had the second most slots in 2018 with six due to a large number of teams in the continental qualifiers (34) and the high performance of their teams in 2014). Every confederation was awarded the same slot allocation with three, determined by the ranking of its Continental Championships in 2023. As a courtesy, the host team receives an automatic berth selection, as has happened with the immediate past tournament winner in 2022. The remaining places were determined by the
FIVB World Ranking at the end of August 2024, without the continental bias. Of FIVB's 222 national federations, 62 women's national teams entered or qualified for the Continental Championships in 2023, while
Russia and
Belarus were barred due to suspension from CEV and FIVB competitions following their country's
invasion of Ukraine. For Europe, eleven additional teams entered the
qualifiers of their Continental Championship. The other nine teams were listed in the FIVB World Ranking at the end of August 2024, but did not compete in their Continental Championships.
Qualified teams Defending
champions Serbia qualified automatically. Therefore, its performance in the
2023 European Championship were not taken into account for the
CEV slots. Amidst the unresolved host selection process, the all-Asian candidate teams—including
Hong Kong,
Indonesia, the
Philippines,
Thailand and
Vietnam—continued to pursue their qualification in the
2023 Asian Championship in
Nakhon Ratchasima, Thailand. If the host team was ranked in the top three, its
AVC slot was allocated to the fourth-place team. However, Indonesia refused to join the tournament. On 22 August 2023,
Brazil,
Argentina and
Colombia became qualified teams from
CSV by topping the round-robin of the
2023 South American Championship, held in
Recife, Brazil. The following day,
Kenya and
Egypt won their semifinals of the
2023 African Championship in
Yaoundé and secured the
CAVB spots. Egypt returned to the World Championship after being absent since 2006. The other spot was awarded to the tournament's host
Cameroon, which defeated
Rwanda in the bronze medal match on 24 August 2023. As Serbia reached the semifinals of the 2023 European Championship on 30 August 2023, the other semifinalists, including
Turkey, the
Netherlands and
Italy qualified for the World Championship. On 3 September 2023, the
NORCECA slots were awarded to
Dominican Republic and the
United States after they surpassed the semifinals of the
2023 NORCECA Championship in Quebec City, Canada. In the bronze medal match the next day,
Canada defeated
Cuba and qualified for the World Championship. On 5 September 2023, Thailand and
China advanced to the final of the 2023 Asian Championship and qualified directly for the World Championship.
Japan followed them after beating Vietnam in the bronze medal match the next day. However, when Thailand was named the host country on 30 August 2024, Vietnam also qualified, making its debut in the tournament. Finally, the remaining fifteen places were allocated to the highest-ranked teams according to the
FIVB World Rankings at the end of August 2024.
Slovakia,
Slovenia and
Sweden made their World Championship debut. Meanwhile,
France,
Spain,
Ukraine and
Greece returned to the tournament after long absences, having last participated in 1974, 1982, 1994, and 2002, respectively. Additionally, Cuba and
Mexico returned to the tournament after missing the 2022 edition. In contrast,
South Korea,
Kazakhstan and
Croatia, all of whom qualified for the 2022 edition, failed to qualify due to insufficient rankings. ==Format==
