Loughlin, 56, was released from the Federal Correctional Institution in Dublin, about 40 miles east of downtown San Francisco, Bureau of Prisons spokesman Scott Taylor said. Loughlin, best known for playing Aunt Becky in the long-running ABC sitcom "Full House," reported to the lockup Oct. 30.
"She is no longer in the custody of the Bureau of Prisons," Taylor said in a statement. "For privacy, safety and security reasons, we cannot discuss release plans for any inmate."
Loughlin and her husband, Mossimo Giannulli, a fashion designer, admitted in May to having paid $500,000 to ringleader Rick Singer to falsely designate their daughters, Olivia Jade Giannulli and Isabella Rose Giannulli, as recruits to the University of Southern California crew team, gaining them special consideration for admission.
Neither of the young women was a rower. The couple went so far as to stage photos of them working out on rowing machines in their admissions applications.
Loughlin's spokesman and attorney declined comment Monday.
Giannulli, 57, reported to prison Nov. 19 and is scheduled to leave the U.S. penitentiary in Lompoc on April 17.

Olivia Jade Giannulli spoke out about the scandal this month, saying she understands how "obvious" it is that the family's privilege has benefited her.
"So when it happened, it didn't feel wrong," she said. "It didn't feel like: 'That's not fair. A lot of people don't have that.'"
