Method and systems are provided for identification of device groups in a network. In an example implementation, a first playback device, while in a first zone group comprising the playback device, the first zone group having a group identification identifying the first zone group, receives an instruction to form a zone group with one or more second playback devices. In response, the first playback device forms a second zone group with the one or more second playback devices. Forming the second zone group involves determining a group identification identifying the second zone group and determining a display name representing the second zone group. In response, the first playback device causes a controller device to update a control interface for the media playback system to display an indication of the second zone group, the indication of the second zone group comprising the determined display name.
