You become a member by donating fifteen dollars ($15) or more and will receive a written confirmation with welcome packet. Member Services will assist you if you would like to join over the phone with your credit card. The WWF Web site also provides several links for secure online membership donation, such as Adoption Center, Monthly Supporter, Gift Planning, Gift Membership, and Partners in Conservation.
Additionally, you can send a check donation to us at:
World Wildlife Fund
1250 Twenty-Fourth Street, N.W.
P.O. Box 97180
Washington, DC 20090-7180
You can also become a WWF member when you sign up for the World Wildlife Fund's Action Network and pledge to act on at least three of the actions that we post on the World Wildlife Fund's Action Center site each year. As a WWF Action Network activist, you will play such a vital role in achieving WWF's mission, so it is only natural that we recognize you as a member of WWF.
