Circulation Auditing Around the World
The International Federation of Audit Bureaux of Circulations (IFABC) is a voluntary cooperative federation of industry-sponsored organizations established in nations throughout the world to verify and report facts about the circulations of publications and related data.

IFABC Objectives
• To encourage and facilitate the exchange of experience between the member organizations.
• To work towards greater standardization and uniformity in the reporting of circulations and other data.
• To encourage the establishment of an audit bureau of circulations in countries where such a bureau does not exist.
• To cooperate with national and international organizations
in any way connected with members' activities.

Membership Eligibility
Although IFABC member bureaus differ in organizational structure and in operational procedures, the Bylaws provide that each bureau elected to membership shall meet the following qualifications:
• Have tripartite sponsorship -- by advertisers, advertising agencies and publishers.
• Use standardized terms and definitions for reporting circulation within the sphere of their own activities.
• Operate as not-for-profit organizations.
• Issue facts about circulation, without opinion.
• Encourage active participation by all eligible advertisers, advertising agencies and publishers.

Affiliated Membership without voting rights may be granted to organizations not qualifying as full members but performing activities leading to the verification and reporting of circulation.
