What DNC scrubbing means
DNC scrubbing checks eligible outbound calling records against applicable national, state, and company-specific do-not-call lists before contact.
The correct lists and exceptions depend on who is calling, the purpose, the recipient, the relationship, and applicable law. National registry screening does not replace an internal do-not-call list. An entity-specific request generally requires the business to stop regardless of broader registry status.
How it works
Before dialing, the system normalizes phone numbers, compares them with current suppression sources, applies approved exceptions, and records the decision. Lists and registry data must be refreshed on the schedule required by the governing rule. New requests should suppress future calls promptly across every connected tool.
Practical use cases
Screening a telemarketing list before dialing
Honoring a company-specific do-not-call request
Removing suppressed records from a reactivation campaign
Scrubbing is a pre-call control, not a one-time cleanup. Run it at the point of action and ensure that downstream exports cannot reintroduce blocked numbers.
Frequently asked questions
Why does DNC scrubbing matter?
Scrubbing is a pre-call control, not a one-time cleanup. Run it at the point of action and ensure that downstream exports cannot reintroduce blocked numbers.
Does a clean DNC result prove a call is permitted?
No. The business must still evaluate consent, caller purpose, technology, time, jurisdiction, prior revocation, and other applicable rules.
