The Al-Anon/Alateen group is the basic unit of Al-Anon Family Groups. It is where close personal interchanges take place among members. At group meetings Al-Anon ideas are discussed and applied to specific personal problems. The entire Al-Anon/Alateen fellowship structure exists for the sole purpose of helping the groups help members.

Registration with the World Service Office ensures a connection with worldwide Al-Anon. Upon registration, the group can count on the WSO for ongoing support including monthly and quarterly postal and electronic mailings.
