Hwang, who held the number 26 shirt during his debut season at Molineux, has been handed the number 11, which was previously worn by Francisco Trincao.
It’s the same number the South Korean regularly wears for his national team, as well as at his former club RB Leipzig.
Meanwhile, Silva has moved across to the 21 shirt, which was vacated by John Ruddy’s summer departure.
Supporters who have already purchased 2022/23 Hwang or Silva home shirts with the previous numbering will be eligible for a free exchange at the Molineux Megastore and at shop.wolves.co.uk.
