Get ready for the launch of World of Warcraft Classic by picking your server and reserving your character name! Those with an active subscription or game time on their World of Warcraft account can create up to three characters per WoW account. WoW Classic launches worldwide 26 August, Monday, 3:00PM PT.
If you’re entering a PvP realm, you can only create characters within the same faction e.g. all must be either Alliance or Horde characters on that realm. WoW Classic beta or stress test characters cannot be used in WoW Classic proper. A maximum of 50 characters can be made across all WoW Classic realms. This does not impact character count on current WoW realms.
You can see the full details and list of realms here. Check out the primer too!
