It's important to remember that you cannot win a EuroMillions prize if you have not bought a ticket. This rule applies in all nine EuroMillions countries. Here is some advice on what to do if you receive a notification that you have won a lottery prize:
I have not bought a ticket
If you have not bought a EuroMillions ticket and have received a notification stating that you have won a prize, it is definitely a scam.
You should never respond to any lottery-related messages that you don't believe are legitimate. Furthermore, no official lottery operator would ask you to respond to an email with personal or financial details. If you have sent any financial information to a potential scammer, you should contact a fraud agency immediately for further advice.
I have bought a ticket in-store
If you bought a ticket at a retailer without having to register any of your personal details, there is no way that the lottery operator knows who you are, so they cannot notify you if you have won. In this instance, any notification that you have won a prize can be treated as a scam.
Some countries require or allow players to provide personal details to purchase lottery tickets. If this applies to you then it is possible that you will receive a notification informing you that you have won. You should check the results of the draw yourself to confirm that you have won, and then follow the instructions on the back of your ticket to initiate the claim.
I played online
If you played online then it is very likely that you will receive an email notification when you win a prize. If you’re unsure about the authenticity of the email, visit the lottery provider’s website (don’t click any links in the email) to log in and check the results.
