From its creation in 2008 until 2019 the championship was open entry, meaning any
World Curling Federation (WCF) member could send a team. With the popularity of curling, and specifically mixed doubles, growing this policy of open entry led to 48 teams participating in the 2019 championship, the final year of open entry. Beginning in 2020 the championship was limited to 20 teams, the top sixteen countries from the previous championship and four countries from a newly created qualification event. Called the World Mixed Doubles Qualification Event, the
inaugural tournament was held in December 2019 in
Howwood, Scotland. This qualification tournament is open to any WCF member not already qualified for the championship. ==Results==
