Those four clubs would go on to found the "Unión de Rugby del Norte" on 29 February 1944.

The most successful teams are Universitario and Tucumán Rugby Club with 21 and 20 titles respectively.

Every year, the best ranked teams from the Noroeste go on to play in the annual Torneo del Interior, where they meet teams from the country's other regional tournaments: Litoral, Centro, Noreste, Pampeana, Oeste and Patagónico.

Like all other provincial unions, the URT organises local competitions for underage and reserve teams.
