Publications such as newspapers, magazines and directories whose supporting documents are auditable for audit by HKABC may join as Publisher Members.

Members of the 2As, 4As and SOPA are automatically members of the HKABC and will receive regular updates of the Bureau's activities.

How often are audits conducted?

During each audit period, member publications must maintain detailed records and documentation to prove the validity of all circulation claims and data. Following the end of the circulation period, the member publication submits its completed audit return form.

The HKABC will then arrange for its appointed auditing firm to conduct the on-site audit, usually within 30 days from the submission of the audit return. On-site audits generally take two to three working days to complete.

The circulation audit is conducted by the HKABC's appointed auditors through an official engagement approved by the Committee. Audits are conducted in accordance with the HKABC Rule Book.

The HKABC will issue the Audit Certificate within 14 working days after conclusion of the on-site audit if further investigation is not required.
