The only requirement for membership is a desire to stop drinking/using.
The only requirement for membership in the 12-Step programs is a desire to stop drinking and drugging. This requirement is unconditional as explained in the Third Tradition without any catches. You do not have to admit you are an alcoholic or addict nor believe in Higher Power. Identity and membership are the principles of the Third Tradition, you are a member when you say you are, period. You do not have to have a sponsor, do the 12 Steps, or follow the many other suggestions. Having a desire to stop drinking and drugging begins our membership, and these other practices can strengthen efforts to be successful. Even if unsuccessful, members are strongly encouraged to keep coming back and keep trying. Many of us tried and failed several times before recovery really began to stick. Open mindedness, willingness, faith, and courage in our ability to love and carry the message to everyone is the basis of the Third Tradition.
