Frequently Asked Questions

How do I activate my game key? ›

Activation depends on the game's platform. For Steam, open the client and select "Activate a Product on Steam...". For Microsoft Store, redeem via your Microsoft account. For Ubisoft Connect, EA App, Epic Games, or GOG, log into the respective client, access your profile or settings menu, and select "Activate Key" or "Redeem Code". Always verify the specific instructions provided by the store upon purchase.

What is the difference between Store Types (Authorized, Reseller, Marketplace)? ›

Authorized Stores get keys directly from game publishers. Key Resellers buy official keys in bulk to offer lower prices with instant delivery. Marketplaces are platforms where third-party vendors list and sell digital keys.

Are the keys sold by partner stores safe and legal? ›

Yes! All stores listed on our platform are vetted for reliability. Authorized stores work directly with publishers, while reputable key stores and marketplaces guarantee valid activation keys for Steam, Microsoft, and other major gaming platforms.
