According to the Eyewitness News platform, Zuma has been at the Estcourt Correctional Centre in the KwaZulu-Natal province since Wednesday.
Zuma became the first president of South Africa to be arrested since it switched to democracy, and the first leader in the country's history to be jailed.
The 79-year-old former president is currently under investigation over corruption that allegedly flourished during his rule from 2009 to 2018. He was forced out of power in 2018 amid a sprawling corruption scandal.
