The knockout stage is still scheduled for November.
From 2022, the group stage will be played in four cities instead of three in 2021 and one, Madrid, in 2019 (the 2020 edition was canceled due to covid).
But until then, the group stage and the knockout stage were linked at the end of the season.
From now on, the two phases will therefore be separated: in 2022, the first is scheduled from September 14 to 18 and the second (quarter-finals, semi-finals and final) from November 23 to 27, said the ITF.
"The host cities should be designated quickly in March," adds the body.
"The changes take into account feedback from players and captains to lighten the schedule by ending a week earlier than in 2021," said the ITF.
For the 2022 edition, defending champions Russia and runners-up Croatia are automatically qualified for the group stage, as well as invited Serbia and Great Britain.
The other twelve nations are due to go through a qualifying round scheduled for March 4-5 and played in the old-fashioned format of home or away games.

The new format of the Davis Cup, introduced in 2019, has been widely criticized in particular because it has distorted the competition by national teams more than a century old by depriving it in particular of its magical atmosphere.
In Madrid in 2019, Spain, by going all the way, had saved appearances in terms of the atmosphere, while most of the meetings had taken place in anonymity and a gloomy silence.
In 2021, the competition was dispersed in its group stage over three sites, the idea being that three teams - Spain in Madrid, Italy in Turin and Austria in Innsbruck - could take advantage of their audience.
