Argentina will play in Group B alongside Colombia, Paraguay and guests Qatar, the 2022 World Cup hosts and current Asian champions.
Messi, who only returned to the Argentina squad in March after an eight-month absence following the World Cup in Russia, will turn 32 during the competition.
Di Maria, like Messi, made his post-World Cup return in March ahead of friendlies against Venezuela and Morocco, but Aguero had not been called up since Argentina’s 4-3 last 16 defeat to eventual champions France in Russia.
Argentina have not won the Copa America, or any major international tournament, since 1993, losing in the final in four of the last five editions of the continental showpiece.
