How does multiple active service accounts work?

[Kirito]

Thanks, you explained it... just one last question... if I have two or more active service accounts, and I register an item code. Will the item code be a permanent option to both active service accounts or do they ask me to choose a service to apply it to?

You will need to choose which Service account the item code will be applied to. It can only be applied to one of them. After you have finished applying the code, it will appear in the list of "permanent" options at the bottom of the Options page for the Service account you applied it to. It will not be available at all for any option (character) on any other Service account.
