A 2021 Tour Card is needed to compete in Professional Darts Corporation ProTour tournaments.
The remaining places will be awarded at the 2021 Q-Schools, with the final four days of competition awarding one Tour Card per day from the UK Q-School and 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] Harry Ward and Kyle Anderson resigned their cards after the 2021 PDC World Darts Championship, which allowed Mark McGeeney and Maik Kuivenhoven to move into the top 64 and retain their Tour Cards.
[2] Andy Boulton also switched his allegiance from England to Scotland on residency grounds.
