The team tag (or clan tag) is a feature in Counter-Strike: Source and Counter-Strike: Global Offensive allowing a shortened version of a clan or group name before the player's actual name. These tags are only available on the PC version of the game, and are based on the abbreviation of a steam group.
Once a group has set the abbreviation, the user can select the tag in-game by going to Game Options » Team Options » Steam Group Clan Tag.
Player can choose Clan tag by going to OPTIONS » "Multiplayer" tab » "Advanced..." » "Clan tag".
- Enabling a team tag in-game will only affect the player's name within that particular game. As such, the team tag will not show up on the player's Steam profile, nor will it show up as part of the user's past aliases if the team tag is changed.
