On 29 May 2016, after being named as a stand-by player for the year's European Championship, Bellerín made his debut for the full squad by starting in a 3–1 friendly win against Bosnia and Herzegovina at the AFG Arena in St. Gallen, Switzerland. Two days later, he was chosen for the final squad after Dani Carvajal withdrew through injury. He was unused as they reached the last 16.
