IBM Clubs have historically fallen into two categories: Local Clubs typically based at IBM locations or associated with a former IBM location, and Retiree Clubs typically serving a geographical area for the benefit of those retiring and living in that area.

Local Clubs use the constitution for IBM Local Clubs and changes to this constitution are adopted by a majority vote at a national level. Clubs adopt the revisions at their next general meeting. Retiree Clubs each use this base constitution for IBM Retiree Clubs Retiree club may make changes as agreed with the Trustee. Please refer to each Retiree Club's web site for more information.
