Officials announced on Monday that the ticket was sold at Smokings at 2894 DeKalb Pike in East Norriton ahead of the Saturday night drawing.
The ticket matched all five white balls, 14-15-16-19-24, but not the red Powerball 02, to win individual prizes of $1 million, less 25 percent federal withholding.
The other winning ticket was sold at a convenience store in Franklin County.
The Lottery encourages each holder of a winning ticket to sign the back of the ticket, call the Lottery at 717-702-8146 and file a claim at Lottery headquarters in Middletown, Dauphin County, or at any of Lottery's seven area offices.
Claims may be filed at Lottery headquarters Monday through Friday, from 8 a.m. to 4 p.m., and from 8:30 a.m. to 4:30 p.m. at area offices.
The Powerball jackpot grew to an estimated annuity value of $131 million, or $81.4 million cash, for the Wednesday, April 18, drawing.
