Username:
A username is completely unique to your account and can't be changed. If your friend wants to add you, they must have the right username, otherwise they won't be able to find you in a search.
Usernames are made up of letters, numbers, periods (.), and underscores (_). If you see something that you think is a username but has characters outside of the one listed above, you're probably looking at the display name.
Display Name:
Display names are what your friends see in their Chat List, at the top of a chat with you, and in the group info screen. Display names can be changed at any time and can include a variety of letters, numbers, characters, and emojis. You can learn how to change your display name here.
