What happens to a Mega Millions jackpot prize if it is not claimed?
If a jackpot prize is not claimed within the required time limit, each participating state in the Mega Millions game will get back all the money that state contributed to the unclaimed jackpot. Each state uses its unclaimed lottery prizes for different purposes. Claim time limits are listed in the answer to FAQ #7. Contact the lottery where you play to find out how unclaimed prizes are used.
