Your CPNI includes the types of telecommunications and interconnected VoIP services you currently purchase, how you use them and the related billing for those services. CPNI does not include your telephone number, your name or your address. Protecting the confidentiality of your CPNI is your right and our duty under federal law. As an AT&T customer, you can restrict the use of your CPNI even within the AT&T family of companies.
