```

## Remarks

This method returns a pointer to a null-terminated string that represents the unique XBOX User ID for this [chat\_user](https://docs.xbox.com/reference/chat/gamechat2/classes/chat_user/chat_user.md) object. The memory for the returned string pointer remains valid for the life of the `chat_user object`, which is until the user has been removed by a call to the [chat\_manager::remove\_user](https://docs.xbox.com/reference/chat/gamechat2/classes/chat_manager/methods/chat_manager_remove_user.md) method. For more information about managing users with the local [chat\_manager](https://docs.xbox.com/reference/chat/gamechat2/classes/chat_manager/chat_manager.md) instance for your app, see the [Adding users to Game Chat 2](https://docs.xbox.com/services/xbox-services/multiplayer/chat/game-chat2/using-game-chat-2.md#adding_users_to_game_chat_2) section in [Using the Game Chat 2 C++ API](https://docs.xbox.com/services/xbox-services/multiplayer/chat/game-chat2/using-game-chat-2.md).
