The final shortlist was announced on 28 August 2020 with an online vote due to open a week later on 5 September 2020 to decide the winning entry alongside a professional jury.

The submissions accepted by UA:PBC were revealed online and users had until 27 August 2020 to vote for their favourite entries by giving a like.

The jury panel that was responsible for 8/9 of the final result consisted of: Jamala (winner of the Eurovision Song Contest 2016), Alina Pash (singer, rapper), Taras Topolya (lead vocalist of Antytila), Ruslana Khazipova (member of Dakh Daughters), Dmytro Shurov (lead vocalist of Pianoboy), Larysa Klyuyevska (music editor at UA:Radio Promin), Timur Miroshnychenko (television presenter, Junior Eurovision commentator for Ukraine), Lyubov Morozova (music critic, host at UA:Kultura).

However, UA:PBC confirmed through its official Instagram account that Oleksandr Balabanov will represent Ukraine at the Junior Eurovision Song Contest 2020.

The second phase of the online voting took place during the live show and began right after the last performance and was open for 15 minutes.
