The TCPA restricts telephone solicitations (i.e. telemarketing) and the use of automated phone equipment. The Act limits the use of pre-recorded voice messages, automatic dialing, and SMS and fax use. Without explicit customer consent, companies must adhere to strict solicitation rules, solicitors must honor the National Do Not Call Registry, and subscribers may sue a company that does not follow the TCPA guidelines.

Consumer consent is an essential defense under the TCPA and should be a primary focus of any business that communicates with consumers directly via voice call or text.
