In late February, the FCC's Enforcement Bureau issued more than 650 Notices of Apparent Liability to communications service providers for violations of the FCC’s Customer Proprietary Network Information (CPNI) rules and §222 of the Communications Act of 1934, as amended.  

Section 222 imposes the general duty on all telecommunications carriers to protect the confidentiality of their subscribers' proprietary information.  

The Enforcement Bureau determined that more than 600 providers failed to file a required annual compliance certification regarding their policies and procedures designed to safeguard CPNI, while others filed noncompliant certifications.  

Each provider that failed to file the certification received a $20,000 proposed fine, while providers that filed non-compliant certifications received up to $10,000 in proposed fines.
