You can choose a display name to show when your teammates mention you in Slack. If you don't fill in the display name field in your Slack profile, you'll see your full name when people mention you.
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 capitalization.
