Belgian newspaper Het Nieuwsblad reports that the cobbled Classic race will join the top tier of professional races from 2017, with a spot guaranteed until 2019.
The official Twitter page of the race also confirmed the news, however the UCI has yet to make an official announcement.
It will be the first time a race has been granted top tier status since the E3 Harelbeke one-day classic moved up in 2012, and comes as part of the UCI's block of reforms for the WorldTour in 2017.
The UCI said that it hopes that new races in the WorldTour, which must follow “strict standards,” will help underline cycling’s global reach.
Watch: The beauty of Paris-Roubaix
Race organisers Flanders Classics already successfully hold two WorldTour races each year in Ghent-Wevelgem and Tour of Flanders, as well as putting on three other 1.HC ranked races in Omloop Het Nieuwsblad, Scheldeprijs and De Brabantse Pijl.
Dwars door Vlaanderen normally sits on the Wednesday between Monument Milan-San Remo and E3 the following Friday, kicking off three weeks of Classics that culminates with prestigious Paris-Roubaix in mid-April.
Lotto-Soudal's Jens Debusschere took victory in the 2016 edition of Dwars, which has run since 1945 and takes in some of the famous Flanders Hellingen like the Oude Kwaremont and the Paterberg.
