Special Envoy Staffan de Mistura has invited "as many of the parties as possible," including Syrian factions as well as regional and world powers to explore the possibility of peace, the statement said.
The list of the invitees has not been disclosed.
The veteran Italian diplomat hopes the meetings will reveal "where we stand vis-a-vis implementation of the Geneva Communique almost three years since it was adopted," the statement added.
The 2012 communique calls for an immediate end to fighting and the formation of a transitional government.
The four-year conflict between regime forces and various rebel groups has resulted in more than 220,000 deaths and the displacement of an estimated 7.6 million people, according to the UN.
Last week, de Mistura described the consultations in Geneva as a "stress test" of the parties` willingness to find a peaceful solution to the conflict.
"This is not a conference, this is not a Geneva III, this is a series of consultations, one to one, between myself, my team, and each delegation from each country, but also each delegation from the Syrian environment, all of them," he said, referring to the failed talks three years ago that set out guidelines for peace and political change in Syria.
The militant Daesh group and Syria`s al-Nusra Front would not be invited to the talks, he said.
