A joint bid from the west African countries of Togo and Benin faces rival bids from Tunisia, Zambia and Zimbabwe.
Another joint bid – from Congo-Brazzaville and the neighbouring Democratic Republic of Congo – has been withdrawn, the CAF said.
All four candidates will have 40 minutes to make their presentations to the CAF executive committee, who will study the bid documents and announce a decision on Monday evening.
Zambia are expected to unveil plans to co-host the event with neighbours Malawi, who have sent a letter of intent to the CAF.
Tunisia is the only bidder to have previously hosted the finals, in 1965 and 1994.
The format of the bid process is a departure from the CAF’s previously stated plans to send inspection teams to each bidding country before making a final decision.
CAF president Issa Hayatou had argued earlier this year that visits were necessary to avoid the embarassment of awarding the finals to countries who subsequently had to withdraw.
Zimbabwe were removed as hosts of the 2000 finals because of a lack of preparation and Kenya (1996), Zaire (1994) and Zambia (1988) all defaulted for financial reasons.
