WOW - Paid Character Name Changes Are Here : World of Warcraft General Discussions

We're happy to announce that through the wonders of modern gnomish engineering, you are now able to change your characters' names. Finally, you can turn the moniker that seemed like a good idea at the time into something more befitting your true standing in World of Warcraft.

Visit Account Management to begin the paid character-name-change process. The fee is $10 per name change. As with our recent addition of voice chat to the game, this feature is being rolled out across all realms in several phases. Enjoy this new feature and the subsequent effect that your bold new name will have on friends and foes alike.
