To become an International UN Volunteer, you have to first register yourself on the UNV ROSTER system.
Here are the guidelines how to register.
Notice
UNDP and UNV, as a matter of practice, do not charge any application, processing or training fee at any stage of the recruitment process. If you have any questions as to UNV volunteer opportunities you may have received, please refer to this website.
UNDP and UNV are currently aware of fictitious vacancy announcements that are being circulated through the Internet which ask you to remit a fee before you can be given a UNV position or before you can register for training. If you believe that you have received such a notice, please forward it, and any other related information you have received, to scamalert((at))undp((dot))org.
Since logos, emblems, names and addresses can be easily copied or reproduced, you are advised to take particular care in applying for vacancies, including undertaking all appropriate measures to protect against the unauthorised use of any personal information you may have provided as a result of the scam.
