How to Request a Refund
You can usually request a refund automatically using our support site and selecting the relevant game or product.
We will typically refund purchases to the method of payment used for the original transaction. In some cases, such as those where the original payment method cannot be refunded, we may provide the refund in the form of Battle.net Balance.
If the automated service doesn’t address your needs, our support team is available to help.
Refund Guidelines
Games and Expansions
We refund paid games or expansions within 14 days of purchase, as long as you haven’t played for more than two hours.
Examples include:
- World of Warcraft and its expansions (Battle for Azeroth, Shadowlands)
- Diablo III and its expansions (Reaper of Souls, Rise of the Necromancer)
- Overwatch
- Warcraft III: Reforged
- StarCraft: Remastered

In-Game Items
We’ll refund most items that you buy with real money and use or receive in-game within 14 days of purchase, as long as you have not claimed, opened or otherwise used the item. Examples include:
- Overwatch Loot Boxes
- World of Warcraft Pets and Mounts
- World of Warcraft Character Level Boosts
- WoW Tokens
- StarCraft II Commanders and Mission Packs
- Heroes of the Storm Boosts
Hearthstone packs, heroes, adventures and passes are non-refundable. WoW Tokens listed on the Auction House are non-refundable. Opening a single item as part of a larger bundle purchase counts as claiming that bundle.
Blizzard Balance and Virtual Currency
We’ll refund purchases of Blizzard Balance and ‘Virtual Currency’ within 14 days of purchase, as long as you haven’t spent the currency yet.
The term ‘Virtual Currency’ only applies to in-game currencies purchased with real money.
Examples include:
- Heroes of the Storm Gems
- Overwatch League Tokens
World of Warcraft Game Services
We’ll refund certain World of Warcraft services within three days of purchase. Examples include:
- Race, Name or Faction Changes
- Character Transfers
- Guild Name Changes
A refund will revert the service your character or guild received.
Subscriptions
We’ll refund any unused World of Warcraft subscription within 14 days of the purchase.
We won’t refund subscription time lost due to a suspension and/or permanent account closure. For permanent account closures and suspensions longer than 15 days, we will cancel upcoming recurring subscriptions.
Pre-Purchases
We’ll typically refund any pre-purchased game or product prior to its release, provided you haven’t played the game or expansion for more than two hours via pre-purchase early access.
Some exceptions may apply in cases where the pre-purchase includes in-game benefits that can be claimed for other products. If you’ve already claimed or used those added benefits, the purchase would become non-refundable.
Gift Purchases
We’ll refund unclaimed gifts within 14 days at the purchaser’s request. If the recipient has claimed but not yet used the gift, the recipient must request the refund. Other refund eligibility limitations still apply as listed above.
Eligible gift refunds are credited back to the original purchaser.
Refunds for Third-Party Purchases
We can only provide refunds for purchases made on our own platform. This includes the Blizzard Shop, the Battle.net App and in-game.
We cannot refund games, in-game items or products purchased in retail locations or from other online sellers and storefronts, including on mobile or console. Purchases made through Amazon, Apple, Google, Nintendo, PlayStation, Xbox, etc. are subject to that retailer’s refund policy.
