Yes, there is a national Do Not Call (DNC) safe harbor provision, but it comes with specific requirements. This safe harbor is designed to protect companies from potential legal liabilities under the Telemarketing Sales Rule (TSR) and the Telephone Consumer Protection Act (TCPA), provided they have made a "good faith" effort to comply with DNC regulations.
Companies can avoid penalties for inadvertently contacting individuals on the National DNC Registry if they follow certain guidelines and demonstrate consistent compliance.
