In field hockey, the International Hockey Federation (FIH) does not specify a criterion for numbering players. Nevertheless, in the 2018 Men's and Women's World Cup, the 18 players of each squad were numbered 1–32, with number "1" generally given to goalkeepers, with some exceptions such as Canada men's, with forward Floris van Son or India women's with midfielder Navjot Kaur, both wearing that number.
