The main paid titles available as keys include World of Warcraft expansions (such as The War Within), Diablo IV, StarCraft II paid editions, and Warcraft III: Reforged. Overwatch 2 and Hearthstone are free-to-play base games, so only their expansions or DLC content are sold as keys. See the current listings below for the full selection.

A game key activates a specific title or expansion directly on your Battle.net account.

If you want flexible credit rather than a specific game, visit Blizzard Gift Cards for available options.

Yes. All Blizzard games and content are tied to Battle.net, so an account is required before you can redeem a key. Creating one is free. Once your account is set up, you can redeem your code straight away using the steps above.
