Wales will start their Euro 2020 preparations with a home fixture against Austria in March
The game will take place on March 27, with the venue to be decided at a later date.
Austria return to Wales for the first time since losing a World Cup qualifier 1-0 in Cardiff in September 2017.
Ryan Giggs' side booked their place at Euro 2020 - only Wales' third major tournament in their history - by winning back-to-back games against Azerbaijan and Hungary last month to finish second behind Croatia in their qualifying group.
An FAW delegation is currently in Azerbaijan, where Wales will meet Switzerland and Turkey in their first two games of Euro 2020 before they play Italy in Rome.
The FAW are looking at potential training bases in the capital Baku ahead of their opening game in the pan-European tournament on June 13.
