You can choose which name your teammates use to @mention you in Slack: either your full name or a display name, like your first name only or a nickname.
Here's what each option looks like in a message:
Full nameYou must include a full name in your profile. Unless you’ve updated your profile, we use the full name you gave us when you created your account.
Display nameDisplay names are optional and can contain spaces, non-English characters and capitalisation.
Set your display name
If you don't fill in the display name field in your profile, you will see your full name when people @mention you in Slack.
