IOGT-NTO has about 32.000 members. To be a member of the organisation a personal pledge is given, which promises abstinence from alcohol and other drugs and admits the equal value of all people.

The legal structure of the organisation has its base in the local clubs, based on geographical structure. Each member belongs to a local club. Those clubs are connected to a district, from which there are 23.

The highest authority of the organisation is the congress, which is held every second year. Delegates are elected by the districts.  The congress elects a national board and adopts a plan of action, policy programmes and financial plans and reports.

Between the congresses the national board is responsible for implementing the plan of action.

The district has annual meetings with representatives from the local clubs. A district board is elected and works in the same way as the national board.

The local clubs also have annual meetings to elect a board and adopt a plan of action and financial plan and report. On these meetings all members in that club is entitled to vote.
