[1][2] This Basque/North side participated in the first edition of the Prince of Asturias Cup, an official inter-regional tournament organized by RFEF, at Madrid in 1915[3] and won the title after beating the Catalan team 1–0 with a goal from Juan Legarreta, then holding Centro (a team formed by players from the centre of Spain) to a 1–1 (the Basque goalscorer being Gipuzkoa's Patricio).

[3] Gipuzkoa took on Catalonia four times in friendlies at the end of 1915, with a draw and a narrow loss in Barcelona, followed by a big win (5–1) in San Sebastián and then an equally heavy defeat (4–0) in Irun.

After several disagreements between the clubs of Biscay and Gipuzkoa, which had caused there to be no Basque representation under any banner at the next three Prince of Asturias Cup tournaments and culminated in a pivotal North Championship match between Athletic Bilbao (Biscay) and Real Sociedad (Gipuzkoa) being abandoned,[4] in 1918 the National Committee of the Spanish federation agreed to divide the Northern Federation in these two regions.

The Gipuzkoa team participated in both the 1922–23 and the 1923–24 editions of the revived Prince of Asturias Cup, being knocked out by Catalonia in the quarter-finals on both occasions.

[6][7] The centenary of the Gipuzkoa Federation occurred in 2018,[8] but the organisers opted for a conventional friendly between its two biggest clubs – Real Sociedad and SD Eibar – to mark the occasion rather than any match involving representative teams;[9] that was also the case for the 50th anniversary in 1968, when Real Sociedad played twice against Alavés.
