Sweepstakes and legal name?

You would have to contact Microsoft Rewards support via the contact link at the bottom of the Rewards site to see if they can clarify that for you.

Hello SnakierIce55222,

Since you never registered into this sweepstakes or attempted to reach out to us prior to the sweepstakes ending, we cannot adjust your sweepstakes status. Unfortunately, once a user begins legal negotiations, we can no longer make any more statements on
an issue. Apologies for the inconvenience.

Also to add, on most of the submission/redemption pages for the Microsoft Rewards sweepstakes if you scroll down a tad bit at the bottom of the page, typically in a very fine gray print the rules and conditions will be listed out.

Rather generically you typically need to be above a certain age (can range from 16 to 18 if you're U.S. based it may vary by region) and your proper legal name usually needs to be the name on your Microsoft account or you could technically be dismissed/disqualified
from most sweepstakes otherwise.

Try having the parent (or legal garden) do this for you. Go to Xbox.com to sign up too, or if you are not a member of the rewards program sinning up for that will get you into the sweepstakes

The rule applies to state minimum age of sweepstakes participants, kids aged 13 to 18 must still have parental consent in order to register for sweepstakes or promotions, if a parent or guardian set up your account for you, have them sign in using their
gamertag, and then they can assist you with registering for the sweepstakes. I know its frustrating, but there are legal statutes in each state that companies must abide by in these instances as sweepstakes are considered a gambling opportunity in some states
and gambling ages are restricted to 18 and over. I hope this helps you out! AND GOOD LUCK!! Hope you win!
