You can choose to use your email address or your QQ number as your display ID. This will be shown next to your nickname in all of your chats: while in a group or in a private conversation with a friend.
If you’ve signed up to QQ International using your phone number then your screen name/display ID is your QQ number by default.
To modify your display ID you first need to open your profile information and edit it. This can be done from the Main Panel: click your profile picture, open “My Profile”, then click the icon next to your nickname that says “Change my Display ID”.
This will open a browser page leading you to the QQ ID Center which, at the moment being, is only available in Mandarin Chinese – we suggest you to take a look at this selection of useful applications to translate Mandarin web pages, and many apologies for the inconvenience.
