The league was renamed as the Primera Nacional de Fútbol in 2019 after the RFEF renamed the new division between it and the first tier as Segunda División Pro, after initially naming it Primera División B.
In early 2022, it was confirmed that the league structure would be altered again, after only three seasons: the existing Primera División would be a standalone professional league of 16 teams, a single nationwide 16-team division known as the Primera Federación would be created as the second tier, the existing Segunda División Pro of 32 teams (two regionalised 16-team groups) would become the third tier and be named the Segunda Federación, and the existing Primera Nacional division of 96 teams (six regionalised 16-team groups) would become the fourth tier. These levels would be administered by the RFEF and more closely resemble the men's post-2021 structure, albeit only one professional league and six fourth-tier groups rather than five.[2] The fourth level was renamed the Tercera Federación FUTFEM prior to the 2023–24 season.
