ACT requires a contribution to gain access to the lists. Contributions are based on several categories including subscription length, category, and country of residence. The subscription lengths are in 6 month or 1 year periods. To find your country's Tier level, click on either of the Tier titles. Once you know your country's Tier level, check the subscription category to find the subscription rate for your selected category in that Tier.

• Organizational – For organizational subscription to the lists and/or when Forum information is regularly used by the recipient organization in their programming. Note, if your organization is interested in posting announcements only (and not receiving postings) this is currently free of charge. For more information see the posting page.
• Professional – Individuals who have full-time employment and use the lists for their personal and professional use.
• Student – For full-time undergraduate/graduate students.
