This year's Davis Cup finalists France and Switzerland have both been drawn away in the first round of the 2015 tournament.
France ended the Czech Republic's recent dominance of the Davis Cup with a 4-1 victory in the semi-finals in a tie that was wrapped up after just two days.
They will start their defence with a trip to Germany in the World Group in next year's event, while the Czech Republic - the 2012 and 2013 winners - have a home tie against Australia.
Switzerland's route to the final was somewhat trickier, as they defeated Italy 3-2 in the final four.
First up for Switzerland is fellow European nation Belgium in 2015, the latter maintaining their place in the World Group via a play-off victory over Ukraine.
One of the most intriguing ties pits South American rivals Brazil and Argentina against one another.
The clash marks the first time the two have met in the World Group, while their last encounter occurred in 1980.
For the second year running Great Britain face United States in round one, while other ties see Kazakhstan face Italy, Serbia host Croatia and Japan visit Canada.
The ties will take place between March 6-8.
