Unclaimed prizes are typically returned to the lottery operator for distribution to good causes, depending on your country’s rules. In the United Kingdom, players have 180 days to claim unclaimed winnings. If not claimed, the funds go to the Good Causes Fund. In Ireland, the time period to make a claim is 90 days, and any unclaimed wins go back to the National Lottery.
