How Long Does the Do Not Call Registry Take to Work?

Learn how the National Do Not Call Registry works, why 31 days matters to telemarketers, and what to save when sales calls continue.

THE SHORT ANSWER

Telemarketers using the registry’s compliance procedures must use registry data obtained no more than 31 days before a call. Exceptions and defenses exist, so registration does not make every later call unlawful.

What the 31-day rule actually means

The federal rule prohibits covered telephone solicitations to registered residential subscribers. A seller seeking the rule’s safe-harbor protection must maintain compliance procedures and use a version of the registry obtained no more than 31 days before making the call.

Why repeat calls matter

Federal law provides a potential private action when a person receives more than one call within a 12-month period by or on behalf of the same entity in violation of the regulations. Permission, an established relationship, personal relationships, caller identity, and other facts can affect the analysis.
