The duo will join compatriot and world no.14 Feliciano Lopez, whose participation in the ATP 250 event was confirmed earlier this month, reported Xinhua.
Robredo, currently ranked 17th in the world, will compete in the tournament for the fifth time, having won the title in 2009. It will be the third Brazil Open appearance for the 33rd-ranked Verdasco.
The Feb 9-15 event will be played on clay at the Ibirapuera Arena in Sao Paulo.
