The series is scheduled to start in Trinidad on March 31 and end in Dominica on May 14.
The one-dayers will be particularly key as September represents the cut-off for direct qualification for the 2019 World Cup where only the top eight nations are guaranteed a place in the 10-team tournament.
A 10-nation qualifying event in 2018 will decide the remaining two spots.
Currently, Pakistan are eighth in the rankings with the West Indies one place behind.
Both teams met in a three-Test series in Dubai last October with Pakistan winning 2-1.
