That's an increase from 2,954 deaths on Saturday.
The official number of injured has risen from around 16,000 to around 16,700.
Authorities buried more than 150 unidentified bodies in a long row of individual graves on Sunday, as witnessed by AFP journalists.
The devastation is enormous after the two earthquakes on June 24, and thousands of people are still missing.
The magnitude of the first earthquake was measured at 7.2, according to the US Geological Survey (USGS). The second at 7.5.
The quakes were the most powerful to hit Venezuela in over a century and occurred within a minute near Morón on the coast.
