Stewart is assigned a number -- but not yet a prison
She still doesn't know where she'll be spending five months in prison. But Martha Stewart already has a new identity -- as far as the federal prison system is concerned. She's been designated as inmate number 55170--054. Federal marshals assigned that number to Stewart, who has to start serving her sentence by October eighth. The number now appears under Stewart's name on the US Bureau of Prisons Web site.
