DGN stands for Do Good Number. Every time a volunteer submit a Do Good Offer, a DGN is automatically generated from our system to identify the application. The DGN is a unique random key of numbers. The purpose of DGN is for charities, volunteers and Ho-Sum staffs to address the offer efficiently during communication, and thus to avoid any misunderstanding.. Virtual volunteering project allows volunteers to contribute without physical present.
