Telemarketing in the United States involves multiple requirements such as federal DNC, internal corporate do-not-call lists, state-level regulations, and TCPA. Merely determining whether a number is valid does not mean that marketing contact can be made.
Marketing lists may contain DNC registration numbers
High-risk numbers that have been subject to complaints or litigation are difficult to find
Multiple risk databases are scattered and manual verification costs are high
Agents mistakenly dialing sensitive numbers may trigger complaints
Lack of unified risk labeling and list blocking mechanism
