A Note for Steam Users

Windows PC and Steam are treated as separate platforms. Please note that if you own the Steam version of FINAL FANTASY XIV, you will have to start the client from Steam as well. It is not possible to log into a Steam Service Account using the regular Windows client.

Steam users can find their 20-digit Dawntrail registration code by navigating to their Steam game library. Right-click on "FINAL FANTASY XIV Online", select "Manage" and then "CD keys". All your FINAL FANTASY XIV codes will be listed there, including the Dawntrail expansion code.

For users who purchased from the Microsoft Store
