As the Copa RFEF is for lower division clubs, the top sides in the region such as Athletic Bilbao and Real Sociedad have never entered the main competition or the qualifying phase.
The opening nationwide rounds pair entrants from either the same autonomous community or one nearby (such as Navarre or Cantabria), so it is common for the Basque teams to eliminate each other.
The most successful Basque qualifier to the national phase was Real Unión, who won the entire competition in 2015, defeating CD Castellón 4–0 on aggregate.
From 1930 until 1987, Biscay and Gipuzkoa operated separate provincial competitions for their non-professional clubs, with the winners of each qualifying for the national Campeonato de Aficionados, the predecessor to the Copa Federación.
[24] The most successful team in Biscay was Erandio with 13 wins, far ahead of Indautxu on 6, while in Gipuzkoa Real Unión, CD Logroñés and Mondragón won four titles apiece.
