The Tercera División de Fútbol Sala Masculina, formerly known as Primera Nacional B, is the fourth level according to the Spanish futsal league system. Founded in 1990, it is managed by the Real Federación Española de Fútbol.
The Tercera División de Fútbol Sala Masculina works similar to the Tercera Federación of Spanish football. It is the fourth tier like the former Tercera División, and it is divided into twenty-four groups, corresponding to the Autonomous communities of Spain, excepting Catalonia which has two groups (1 and 2), Community of Madrid (3 and 4), Canary Islands (11 âÂÂProvince of Las Palmasâ and 12 âÂÂProvince of Santa Cruz de TenerifeâÂÂ), Valencian Community (14 and 15 âÂÂProvince of AlicanteâÂÂ), Andalusia (17 âÂÂâ and 18 âÂÂâÂÂ).
All the groups are made up by sixteen teams, except the groups 7 (Navarre âÂÂthirteen teamsâÂÂ), 11 (Canary Islands âÂÂeleven teamsâÂÂ), 12 (Canary Islands âÂÂfourteen teamsâÂÂ), 19 (Balearic Islands âÂÂfourteen teamsâÂÂ), 20 (La Rioja âÂÂfourteen teamsâÂÂ) and 21 (Cantabria âÂÂeight teamsâÂÂ). Group 22 (Ceuta) just has one team, Real Sociedad La Pantera; and Group 24 (Melilla) does not have any team for this current season.
Every group champion promotes directly to Segunda División B. The runner-ups qualify for the national promotion playoff, which will be a single knockout round, home and away tie.
