On 17 August 2018,
Brazil national team manager
Tite included Hugo in the 23-man roster for a pair of friendlies against the
United States and
El Salvador. However, he did not feature in either match. On 13 December 2018, Hugo was called up to the
2019 South American U-20 Championship squad for Brazil. Despite being part of the team, he did not play in any matches during the tournament. On 26 May 2025, he returned to the
Canarinho in
Carlo Ancelotti's first call-up as coach of Brazil, ahead of the
2026 World Cup qualification matches against Ecuador and Paraguay. He was called up again for the last qualification matches against Chile and Bolivia, but didn't play either. He received his first cap in a 14 October friendly against Japan in Tokyo, which ended in a 3-2 defeat, Brazil's first ever against the Japanese. While the first two goals were attributed to mistakes committed by
Fabrício Bruno, some blamed Souza for the third one, since he deflected a header by
Ayase Ueda into his own net. Coincidentally, the last time a Corinthians goalkeeper played for Brazil was also in a friendly against Japan, when
Cássio came in as a substitute in November 2017. ==Career statistics==
