Intergroups are subsets of OA regions formed by groups of OA meetings nearby to each other. Representatives of intergroups conduct the business of each region. To find meeting information organized according to intergroups, go to OA.org and use the interface to refine the intergroups(s) you seek information for.

Each entry below had two numbers. The first corresponds with a numbered circle on the map above. The five-digit number at the end of each entry is the intergroup’s ID number with the World Service Office of Overeaters Anonymous.
