Membership is a hierarchy and there are two categories of membership: Full Members and Associate Members.[2] As of 22 June 2017, there are 105 members, with 12 Full Members and 93 Associate Members. The Membership Committee  will consider all future requests for membership – full and associate – against an objective set of criteria. There was previously a third level, Affiliate Membership, which was removed in June 2017 with all previous Affiliate Members becoming Associate Members.[6]

Among these 12 nations, Sri Lanka, Zimbabwe, Bangladesh, Afghanistan and Ireland have played as associate nations under the ICC before becoming full members.
