The John Birch Society is dependent upon members to work with leaders within their communities and spheres of influence. Members are encouraged to create lasting relationships with leaders, educate them on relevant issues and work to accomplish the mission of The John Birch Society.

Due to member privacy, The John Birch Society does not publish its membership list nor divulge the size of membership. Member information is never sold or shared in any way.

The John Birch Society is headquartered in Appleton, Wis. at 770 N. Westhill Blvd, Appleton, WI 54914. Staff here handles the daily operations of the organization. Two buildings house the staff. Members are locally organized into small chapters (usually less than 20 people). Each chapter has a volunteer leader. Chapters are then organized into sections (a minimum of 3 chapters). Each section has a Volunteer Section Leader.

The mission of The John Birch Society is to bring about less government, more responsibility, and — with God's help — a better world by providing leadership, education, and organized volunteer action in accordance with moral and Constitutional principles. This means we focus on an individual level of having more responsibility to govern ourselves in our daily lives as opposed to being governed. This responsibility is carried through all aspects of life, including family, business, social, church, and community. We advocate looking to the Ten Commandments for a moral guide and to the founding documents of America’s founders that describe the proper role and structure of government.
