Lisbon - Luis Figo identified the five national federations that formally nominated him to run for Fifa president against Sepp Blatter.
The Portugal great said in a statement he received the endorsement of Denmark, Luxembourg, Macedonia, Montenegro, and Poland.
He was also backed by his own national federation before the entry deadline on Thursday.
Figo has little track record in football politics, and was a surprise entry on Wednesday.
“It has been a great start - my thanks to everyone concerned,” the former Barcelona and Real Madid playmaker said.
“I would like to thank my colleagues and friends from the nominating FAs and across the global football family who have already given their backing to my campaign, and sent messages encouraging me in this mission.”
Blatter, who has headed Fifa for 17 years, has not said which five of Fifa's 209 members nominated him for the May 29 election.
Opposition to Blatter is centered on Europe, with UEFA the only one of Fifa's six continental confederations actively campaigning against him.
Netherlands federation president Michael van Praag named the five European associations nominating him, at his campaign launch on Wednesday: Belgium, the Faroe Islands, Romania, Scotland and Sweden.
England has said it is formally backing Prince Ali bin al-Hussein of Jordan, the Fifa vice president for Asia who shapes as the only non-European in the contest.
Former Fifa official Jerome Champagne, a longtime Blatter ally from France, also sought to enter the race, though he has not confirmed if he submitted nomination papers.
It could be two weeks before the official field of candidates is confirmed.
Fifa has created an election oversight panel, led by its audit committee chairman Domenico Scala, which will validate nomination papers and receive vetting reports from Fifa's ethics committee.
