Martha Stewart (search) still does not know where she will do her time, but she has already been designated federal inmate No. 55170-054.

The celebrity homemaker, who must begin serving her five-month prison sentence by Oct. 8, was assigned the number by federal marshals.

The number now appears under Stewart's name on the U.S. Bureau of Prisons (search) Web site. She is also listed as "in transit," but the designation simply means she has a reporting date, prisons spokesman Dan Dunne said Monday.

Prisons officials still must decide where Stewart will serve her time. Stewart was sentenced in July after she was convicted of lying about why she sold ImClone Systems Inc. (IMCL) stock in 2001.

The U.S. Bureau of Prisons must now decide where Stewart will serve her time. The minimum-security facility in Connecticut, close to Stewart's home in Westport, is her first choice.

Stewart and her former stockbroker, Peter Bacanovic (search), were convicted in March. He received the identical sentence of five months in prison and five months of house arrest.

Stewart resigned as CEO of her company when she was indicted and gave up her seat on the board after she was convicted. She remains its leading creative force and holds the title of founding editorial director..
