The Fifa Council has ratified the decision to give Africa nine automatic places when the World Cup expands to 48 teams in 2026.
The move was confirmed on Wednesday in Bahrain – the continent currently has five spots at the tournament.
A tenth African country will take part in a six-nation play-off tournament to decide the last two spots.
The Bureau of the Fifa Council made the original proposal of how it planned to allocate the 48 places on 30 March.
Egypt are in control of Group E of Africa’s 2018 World Cup qualification while Uganda Cranes, who beat Congo Brazzaville in their last game in Kampala, are second place, with Ghana in third and the Diables Rouges (Red Devils) rock-bottom.
Group action returns next year when Uganda host Egypt on August 27 in game three of these qualifiers, before Ghana play host to Congo the following day.
