In the UK, EuroMillions prizes must be claimed within 180 days of the draw, whether the win is a small payout, a jackpot, or a Millionaire Maker prize.
Players are advised to sign the back of their ticket and keep it secure, as it serves as proof of ownership.
If a prize isn’t claimed within the 180‑day window, the money—along with any interest it has earned—is allocated to National Lottery‑funded projects across the UK.
