The convention will be inaugurated by RSS Chief Mohan Bhagwat and would be attended by the organisation's second- in-command Suresh Bhayyaji Joshi, besides a host of other leaders.
The meeting, which is expected see the presence of 1.6 lakh volunteers working for the 800-odd RSS-affiliated bodies, is the second one of its kind being held. The first such convention was held in Bangaluru in 2010.
The "Rashtriya Seva Sangam" starting April 3 at Alipur on the outskirts of Delhi, will "showcase" the strength and networking of RSS-affiliated organisations that are working among the socially deprived sections.
Social workers and sponsors of social service projects from the industry and other fields will attend the mega event.
Nearly 4000 delegates are expected to participate in the event being organised under the RSS umbrella community service organisation 'Rashtriya Sewa Bharati'.
