Lottery spokeswoman Tandi Reddick said the winner has 180 days from the date of the drawing to claim the winnings and that it's not uncommon for winners to wait a few days or more.
The jackpot was worth $133 million, but if the winner chooses to take an immediate lump sum payment, the payout would be nearly $57 million after state and federal taxes are taken out.
Mega Millions tickets are sold in 12 states, including New Jersey.
