Internal Do Not Call List
An internal DNC list is the company-maintained record of consumers and merchants who have requested not to be contacted by the specific MCA shop — required by federal regulation to be honored for at least 5 years and a critical TCPA compliance control.
Why This Matters
Internal DNC is distinct from National DNC — federal rules require any company conducting telemarketing to maintain an internal opt-out list and honor opt-out requests across all phone numbers and channels. Failure to honor internal DNC requests is a per-call TCPA violation regardless of original consent status. Best practices: capture opt-out requests via call disposition codes, route them automatically to centralized DNC database, suppress all subsequent dialer attempts to the merchant across all phone numbers and lines of business, and audit dialer compliance monthly.
Frequently Asked Questions
Frequently Asked Questions
How long must internal DNC requests be honored?
Federal law requires minimum 5 years from opt-out date. Best practice is permanent suppression unless the merchant explicitly re-opts-in through documented re-consent. Many state laws and TCPA case law support indefinite suppression.
Does internal DNC apply to text messages?
Yes — TCPA opt-out rules apply to all marketing channels (calls, SMS, prerecorded messages). 'STOP' replies to SMS must be honored across all channels for the affected number, not just SMS.
