The 2020 edition of FIBA U20 European Championship was to be held in Klaipėda, Lithuania, but was postponed to 2021 due to COVID-19 pandemic. Since the pandemic continued in 2021, the FIBA Europe decided to hold alternative format of competition to replace traditional format of U20 European Championship where 16 or more teams gather in one place.

Structure

 * The events are to be played on a voluntary participation basis, with promotion/relegation to be frozen across Divisions A, B and C.

 * All other registered teams, ranked 19 and lower, to play in tournaments of up to six teams each (Groups D/E).
 * All tournaments to be played in Round Robin format, with groups to be created by "serpentine" style allocation, taking the hosting situation into consideration.
