can u unredeem fortnite gift cards code if you sent them to the wrong email?

The instructions that were sent were wrong. The website to redeem them on is correct and you would choose to have them either email the Visa gift card or mail you a card. Since you ordered a Visa gift card from the vault, you would get a Vida gift card,
not an Xbox gift card.

There are two ways to gift to friends. The first, email gifting, will give you a redeemable code after purchase (usually sent to you via email). This one you can then send to your friend. The only drawback is if you get their email address wrong and they may not receive it.

The second method which is the best is gifting directly to their gamertag on your list. That code will be sent to them via the Xbox Message Center and can be redeemed directly on the console.

Also is there any way to “unredeem” the code on the gift card so I can redeem it again to my main?

Hello Alexander M, my name is Oskayra and I will be happy to help you.

I tell you in advance so that there are no misunderstandings, this is a public forum for user-to-user support. We are users who help other users. We do not work for Microsoft, nor Xbox.

Unfortunately, it's unlikely that you'll be able to redeem a Fortnite gift card without the first two digits. These digits are the card's security code, and are necessary to verify that the card is legitimate.

However, there are some things you can try.

Try ordering a duplicate gift card. If the card was purchased at a retail store, you may be able to order a duplicate. To do this, you will need the purchase receipt.

Contact Fortnite support. Fortnite support can help you redeem the gift card if you can provide them with enough information. To do this, you will need the card security code, the email address associated with your Fortnite account, and other information that can help you verify your identity.

If you can't get a duplicate gift card or if Fortnite support can't help you, you may have to forfeit the balance on the card.

Here are some tips to help you avoid this problem in the future:

Save the receipt of the gift card purchase. This will help you get a duplicate card if you lose or damage it.

Avoid writing on the gift card. If you need to write on the card, use a pencil or marker that can be easily erased.

Take a photo of the gift card. This will help you recover the security code if the card is lost or damaged.

I'm sorry for what you're going through, I hope you understand.

Merry christmas.

Sincerely,
Oskayra.

No. Once you redeem a gift card, you can't unredeem it. All you can do is spend the funds.
