The Davis Cup Finals group stage begins this week with Great Britain one of 16 nations trying to make it through to the knockout phase.
Great Britain take on Australia, France and Switzerland in their round-robin group matches at Manchester's AO Arena.
Andy Murray missed the 3-1 victory over Colombia in February but is back in the squad, alongside Cameron Norrie, Dan Evans, Neal Skupski and Jack Draper.
The top two from Britain's group will advance to November's knockout stages.
"We can't wait to play Davis Cup in Manchester in front of a huge home crowd," Britain's captain Leon Smith said.
