in the
2018 FIFA World Cup Fagner was a member of the
Brazilian under-20 team on
2007 South American U-20 Championship, which Brazil went on to win. Fagner was named in Brazil's provisional squad for
Copa América Centenario but was cut from the final squad. On 22 August 2016, Fagner was called up by new
Brazil national team coach
Tite to
2018 World Cup qualification games against
Ecuador and
Colombia. According to Fagner, this is a "unique moment" in his career. On 14 May 2018, Fagner was included by Tite in the 23-man Brazil squad for the
2018 FIFA World Cup in Russia. Initially a back-up to Dani Alves, and then to Danilo who replaced the injured Alves, Fagner made his debut in the competition in the second group stage game, against Costa Rica, which Brazil won 2–0, starting the game due to Danilo's injury. He then proceeded to play the next three games, as Danilo's injuries persisted, with Brazil eventually falling to Belgium in the quarter-finals. In May 2019, he was called for the Copa América, which Brazil was due to host. With Dani Alves playing the entire tournament as captain and starting right-back, Fagner was the only outfield player from the squad to not enter a match during the competition, and the third overall alongside reserve keepers Ederson and Cássio, as Brazil eventually conquered their 9th continental title. ==Career statistics==
