A central office (or intergroup) is an A.A. service that involves partnership among groups in a community just as A.A. groups themselves are partnerships of individuals.  A central office is established to carry out certain functions common to all the groups – functions which are best handled by a central office- and it is usually maintained, supervised, and supported by these groups.  It exists to aid the groups in their common purpose of carrying the A.A. message to the alcoholic who still suffers.
