Canceling an Avis Preferred membership is notoriously less "automated" than signing up. Unlike many modern digital subscriptions, there is often no simple "Cancel" button in the app or on the website. To terminate your membership, you typically must log in to your account on the Avis website, navigate to the "Profile" or "Contact Us" section, and submit a formal request via their online email form. Alternatively, the most effective method is to call Avis Customer Service directly at 1-800-331-1212 (in the US) and ask the agent to deactivate your account. Be prepared for them to ask for your Wizard Number and the reason for your departure. If you are worried about data privacy, you should explicitly request the "deletion of your personal profile" under your local data protection laws (like CCPA or GDPR). Once processed, you will lose access to your points, your expedited "Skip the Counter" privileges, and your saved rental history.
