A 2020 Tour Card is needed to compete in Professional Darts Corporation ProTour tournaments.
The remaining places were awarded at the 2020 Q-Schools, with four days of competition awarding two Tour Cards per day from the UK Q-School and one a day from the European Q-School; with the remaining players being ranked and the top players also receiving Tour Cards.
All players who won a card at either Q-School had their Order of Merit ranking reset to zero.
[1] Raymond van Barneveld retired after the 2020 PDC World Darts Championship, and Corey Cadby also resigned his card which allowed Toni Alcinas and Simon Stevenson to move into the top 64 and retain their Tour Cards.
Jamie Bain resigned his Tour Card after the 2020 PDC World Darts Championship, as he couldn't commit to the full schedule, which opened a space in Q-School as Bain was outside the Top 64.
