IFAC is comprised of 172 members and associates in 129 countries and jurisdictions*, representing approximately 2.5 million accountants in public practice, education, government service, industry, and commerce. IFAC members are professional accountancy organizations recognized by law or general consensus within their countries as substantial national organizations. National organizations may apply to become an IFAC associate where the organization is working toward membership.

Members are required to support IFAC's mission and programs; demonstrate compliance with the Statements of Membership Obligations; be financially and operationally viable, and have an appropriate governance structure; make financial contributions; and meet the other criteria described in the Membership Application Process, the IFAC Constitution, and the IFAC Bylaws. Associate status is open to professional accountancy organizations that do not yet meet all of the member admission criteria, but demonstrate commitment to meeting such criteria and progressing to membership.

IFAC also has Affiliates, organizations that do not meet the associate admission criteria but are involved in the development of the accountancy profession.

IFAC also works with Recognized Regional Organizations and Acknowledged Accountancy Groupings, independent bodies that support the development of the international accountancy profession, facilitate convergence to international standards, and provide leadership in addressing issues affecting the accountancy profession in their region and/or constituencies. Regional Organizations support IFAC members and the profession within a geographic region; Accountancy Groupings bring together professional accountancy organizations with specific commonalities, such as language, culture, proximity, trade, etc.
