First round

After the last minute changes to the format of the competition, the first round will only involve 20 second division A clubs (all except Málaga B and Real Madrid B). Games will be played over one leg at the ground of the first named side, with the ten winners going through to the second round together with the 18 regional sides who got through the qualifying round, plus the four sides relegated from the second division A last season (Córdoba, Terrassa, Salamanca and Pontevedra), plus Real Unión and Zamora, who were exempt from the qualifying round.
