 Amended rules for the 2019–20 edition led to the number of entrants increasing to 125, including winners of the regional divisions at the fifth level.All rounds are single-leg ties with lower division teams hosting the match and the majority of the top-level clubs entering at the First Round (four teams taking part in the Supercopa de España entering in the Third round - last 32), other than the semi-final stage which is played over two legs.This is another change in the 2019–20 edition, with prior editions involving two legs from the point at which the top tier clubs entered in the Fourth round (last 32).
