Tahitian Reynald Temarii and Nigerian Amos Adamu will be summoned as the ethics committee probes allegations they offered to sell their votes when approached by Sunday Times reporters posing as lobbyists for an American consortium.
The newspaper report said Adamu was filmed asking for 500,000 pounds for a personal project and that Oceania Football Confederation president Temarii asked an undercover reporter in Auckland for NZ$3m ($2.27 million) to fund a sports academy at the OFC's headquarters.
The committee, headed by former Switzerland international Claudio Sulser, will also investigate suspicions that bidding nations may have broken the rules by making agreements which FIFA said would constitute a "clear violation of the bid registration document and the code of ethics".
World football's governing body has not said how long the investigation will take nor whether any bids could be disqualified, though a media conference will be held at 16:00 GMT when provisional measures could be announced.
