On 25 May 2021, White was named in England's provisional 33-man squad for UEFA Euro 2020, with the tournament taking place in the summer of 2021 due to the previous year's postponement as a result of the COVID-19 pandemic. This was White's first ever call-up to the national team at any level. He was one of seven players cut from the squad on 1 June, although the players who were cut remained in the squad for the two warm up games against Austria and Romania. White made his England debut coming on as a substitute, replacing Jack Grealish in the 1–0 victory over Austria at the Riverside Stadium on 2 June. He cleared a shot from Alessandro Schöpf off the line, preventing a late equaliser. He became the fifth Brighton player to play for England, and the second in just under three years after Albion team mate and captain Lewis Dunk was capped in November 2018. He made his first start in the second and final warm up match on 6 June, playing the whole match in the 1–0 victory over Romania, again played at the Riverside Stadium. On 7 June, White was named in the 26-man squad for Euro 2020 as a replacement for the injured Trent Alexander-Arnold. White remained unused in the tournament where England finished as runners-up in the Championships. However, Southgate praised the players who made no appearances saying, "they are the ones making this team successful."
