Winners have 182 days from the day of the drawing to claim their prizes. The holders of the tickets sold in February have until mid August to claim their prizes; the holder of the March 28 ticket has until the last week of September.
To win the $1 million prize, tickets must match all five white balls pulled during the drawing, missing only the red Powerball.
Winners are encouraged to sign the back of their ticket and contact the Maryland Lottery and Gaming Control Agency as soon as possible. Prizes must be claimed at the Baltimore Claims Center in Baltimore.
