Out-of-Country Registration and Voting (OCV)

This is the official website for the Out-of-Country Registration and Voting programme for the Southern Sudan Referendum, which took place between 9 January 2011 and 15 January 2011.

Please note that final results for the entire Referendum (South Sudan, North Sudan and OCV) are due to be announced on 7 February 2011 if there are no appeals, and on 14 February 2011 if there are appeals.

The Southern Sudan Referendum gave the people of Southern Sudan the opportunity to vote for either:

  • Confirmation of the unity of Sudan, or
  • Secession
The body which was in charge of organizing this Referendum is the Southern Sudan Referendum Commission (SSRC), along with its operational arm, the Southern Sudan Referendum Bureau (SSRB). Both are independent from the governments of both Sudan and Southern Sudan. Provision was made by the SSRC and the SSRB for Southern Sudanese people who live outside Sudan to be able to register and vote in the Referendum.

Out-of-Country registration and voting (OCV) centres were established in the eight countries with the largest numbers of Southern Sudanese living outside Sudan. These are: Australia, Canada, Egypt, Ethiopia, Kenya, Uganda, the United Kingdom (UK) and the United States of America (USA). The International Organization for Migration (IOM) has been assisting the SSRC at its request in organizing the OCV.
