Troubleshooting

Region mismatch

Since Battle.net doesn’t transfer codes between regions, make sure to verify before ordering.

Already redeemed

Codes can only be redeemed once. To check the activity, visit Account > Transaction History.

Cashier never activated the card

Since Blizzard can’t activate retail cards remotely, you have to bring your receipt back to the retailer.

Diablo Immortal Promo Code rejected

You can’t redeem a Diablo promo code on Battle.net’s redemption page; it has to be on their own page.

FAQ

Can I redeem a Battle.net code on mobile?

Yes, open battle.net/account/code-redeem in your phone’s browser and sign in. The Battle.net mobile app itself doesn’t support code redemption, but the browser flow works from any phone or tablet.

Do Battle.net codes expire?

Most game and gift codes don’t expire, but promotional codes tied to time-limited events (like season passes or event bundles) do. Check the details on your order or the event announcement.

Can I redeem a Battle.net code on Xbox or PlayStation?

No. Battle.net codes only work in the Blizzard Battle.net app for PC and Mac. If you bought a console version of a Blizzard game, you’ll redeem the code on the platform store, not on Battle.net.

Can I transfer a redeemed game to a different Battle.net account?

No. Once a code is redeemed, it’s permanently tied to that account. Confirm which account is signed in before pasting the code, especially if you play across multiple regional accounts.

Why do some Battle.net codes only work in certain regions?

Codes match the Blizzard shop region where they were originally sold. An EU-region code won’t redeem on an Americas account — you’ll need a matching regional account, or contact Blizzard support with proof of purchase.
