Automated DNC scrubbing

The primary function of a good dialer for DNC management is automated scrubbing. Before any calls are placed, your dialer should automatically compare your call list against both the National DNC Registry and your internal DNC list. This process should happen frequently, ideally before every new campaign.

This ensures that numbers on these lists are not dialed. It is not something you should do manually, as human error is common. Always ensure your dialer provider maintains an up-to-date National DNC Registry for compliance. This is not legal advice.

Internal DNC list management

Beyond the National DNC, your dialer must maintain an internal DNC list specific to your company. Any time a homeowner requests not to be called, your setters or closers should have a clear, immediate way to add that number to your internal DNC list within the dialer. This might be a button or a specific code to enter.

This internal list is critical because some homeowners might not be on the national registry but still do not want calls from you. Your dialer should always prioritize both lists before making a connection.

Handling opt-out requests during a call

Train your team to recognize and immediately act on DNC requests made during a live call. If a homeowner says, 'Do not call me again,' the setter or closer must log that request directly into the dialer or CRM. The dialer should then automatically update the internal DNC list.

There should be no ambiguity or delay. The call should end respectfully after the request is made and logged. This is a non-negotiable compliance point. For more on cold outreach rules, see /learn/tcpa-and-cold-outreach-basics.

Integration with your CRM

For seamless operations, your dialer should integrate with your CRM. When a number is added to the DNC list in the dialer, that information should sync automatically to the corresponding lead record in your CRM. This prevents any other team member from accidentally contacting that homeowner through a different channel, like email or text.

This integration provides a holistic view of the homeowner's communication preferences and ensures that all outreach efforts respect his or her wishes. It is about maintaining a single source of truth for all lead data. You can learn more about working leads you just bought at /how-to-work-your-leads.

Reporting and audit trails

Your dialer should provide robust reporting features that allow you to track DNC compliance. You need to be able to generate reports showing when numbers were added to your DNC lists, by whom, and at what time. This audit trail is crucial if you ever face a complaint or audit.

Regularly review these reports to ensure your team is following proper procedures and that your system is functioning as intended. This proactive approach helps identify any gaps in your DNC management process and keeps you compliant. For more on comparing lead types, check out /lead-types.

Questions people ask

Does my dialer need to check state-specific DNC lists?

Yes, some states have their own DNC lists that are separate from the national registry. Your dialer should ideally be able to scrub against these as well, especially if you operate in those states. Always check local regulations, as this is not legal advice.

What if a homeowner who is on the DNC list texts me first?

If a homeowner on a DNC list initiates contact (e.g., by replying to a text from Speed to Seller), he or she has implicitly given you consent to communicate regarding that specific inquiry. You can respond to his or her text or call him or her back. However, if he or she then asks you not to contact him or her again, that request overrides prior consent.

How often should I update my DNC lists in the dialer?

Your internal DNC list should update in real-time as requests come in. For the National DNC Registry, your dialer provider should be updating it regularly, typically every 30 days. Confirm this with your provider to ensure continuous compliance.
