For women, UEFA and the AFC run under-19 championships instead of under-20; CONCACAF, CONMEBOL, and the OFC run under-20 championships; and the CAF's under-20 "championship" is strictly a World Cup qualifier and currently has no championship match, as that confederation receives more than one berth in the U-20 Women's World Cup.
