Semi-final Allocation Draw
The draw to determine the allocation of the participating countries into their respective semi-finals took place on 14 February 2021. The first part of the draw determined in which semi-final the Big Six would have to vote. The second part of the draw decided in which half of the respective semi-finals each country would perform, with the exact running order determined by the producers of the show at a later date. Twenty-one countries participated in each semi-final. From each semi-final, ten countries joined the "Big 6" in the final, where a total of twenty-six countries participated.

The forty-two semi-finalists were allocated into six pots, based on their geographical place and cultural similarities. Drawing from different pots helps in reducing the chance of so-called neighbour voting and increasing suspense in the semi-finals. Each time a country was drawn from the pot, its semi-final and half of the semi-final was determined.

The six pots were the following:

Semi-final 1
Twenty-one countries participated in the first semi-final. Laos, Tajikistan and Thailand also voted in this semi-final.

Semi-final 2
Twenty-one countries participated in the second semi-final. Indonesia, New Caledonia and Taiwan also voted in this semi-final.

Final
Twenty-six countries participated in the final, with all 48 participating countries eligible to vote.
