ACE Philippines, established in 2002, is the second affiliate charter country member of ACE. It was formally organized in May 2003 when the first ACE Philippines general membership meeting was held to ratify the organization's constitution and to elect the members of the board of directors. The organization is registered as a foundation with the Philippines Securities and Exchange Commission. The secretariat is based at the International Rice Research Institute (IRRI) in Los Baños, Philippines. The current ACE Philippines president and charter representative, Roger Barroga of the Philippine Rice Research Institute (PhilRice), was elected ACE international director-elect in 2004.

The members of ACE Philippines are professional communication practitioners who come from various public and private organizations including academic institutions, government and public goods agencies, research and development organizations, and private communication entities. ACE Philippines is undertaking a program of activities that (a) enhances the professionalism and capabilities of its member-communicators, and (b) supports the international ACE organization's thrusts and programs, which include a national Critique and Awards program and an annual inter-institutional communication workshop (ICW) held each May.

There are currently 87 members in good standing coming from 15 local, regional, and international organizations in the Philippines, but almost a hundred participants from all over the Philippines regularly attend the ICW and participate in other ACE-related activities.
