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 name You 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 name Display names are optional and can contain spaces, non-English characters, and capitalization.  

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.

Note: If your Workspace Owner has enabled single sign-on, members' ability to edit their personal information, including display names and email addresses, may be restricted.

Reserved names

There are several words that we reserve to avoid confusion in your workspace. These words can't be used for display or full names in Slack. The following names can't be used:

• English: archive, archived, archives, all, channel, channels, create, delete, deleted-channel, edit, everyone, general, group, groups, here, me, ms, slack, slackbot, today, you
