Managing an internal Do Not Call list
An internal Do Not Call list is your own record of people who asked your company to stop contacting them. It is separate from the National DNC Registry and is required regardless of registry scrubbing. Record every opt-out promptly, keep the entry indefinitely, scrub against it before every send, and make it account-wide across channels.
Most teams know about the National Do Not Call Registry. Fewer realize that they are also expected to maintain their own internal Do Not Call list — a company-specific suppression list of people who have asked you to stop. The two are different, and you need both. This is general information for outreach teams, not legal advice; your compliance team should confirm how the requirements apply to your program.
Internal DNC vs the National Registry
The National DNC Registry is a government-maintained list of consumers who have opted out of telemarketing broadly. You scrub against it to avoid contacting people who have registered.
Your internal DNC list is different. It records the people who specifically told your business to stop — by replying STOP, asking a rep to remove them, unsubscribing, or otherwise opting out. Honoring company-specific do-not-call requests is a longstanding expectation, and it applies even to numbers that are not on the national registry and even where an exemption might otherwise let you call.
In short: the national registry protects people from the industry; your internal list protects people from you.
What belongs on the list
Add an entry whenever someone asks not to be contacted, through any channel:
- SMS opt-outs — STOP, UNSUBSCRIBE, CANCEL, and similar keywords.
- Verbal requests on a call ("take me off your list").
- Web unsubscribes and form submissions.
- Email or written requests to stop.
- Complaints that amount to a request to stop.
Capture enough to act on it and prove it later: the phone number, the date and time of the request, and how it came in.
Four rules for running it well
1. Record promptly
Do-not-call requests should be recorded and honored promptly. A request that sits in an inbox for a week is a request you have effectively ignored. Automating capture — so a STOP reply immediately writes to the suppression list — removes the human-delay failure mode.
2. Keep entries indefinitely
An internal do-not-call request does not expire on its own. Unless the person affirmatively opts back in, treat the suppression as permanent. Do not "refresh" your list by dropping old opt-outs so you can contact them again.
3. Scrub before every send
The list only works if you check it. Every campaign should be scrubbed against your internal suppression list — alongside the national registry — before any message goes out. A suppression list you do not consult is not protecting anyone.
4. Make it account-wide and cross-channel
If someone opts out of your SMS, do not call them with your dialer the next day. The strongest practice is to treat an opt-out as a request to stop across channels and across all your campaigns, not a narrow removal from one list. Account-wide suppression is both safer and what recipients expect.
Keep the audit trail
If you are ever challenged, you need to show that you had a request, recorded it, and stopped. Maintain an exportable record of each suppression: the number, when the request arrived, and when the number was suppressed. This turns "we honor opt-outs" from a claim into something you can demonstrate.
How Fivra supports this
Fivra maintains suppression at the account level: STOP and opt-out replies suppress the contact automatically and account-wide, and DNC and suppression screening runs before contacts are messaged. Suppression and screening activity is written to append-only audit logs you can export as CSV or JSON, so you have the record if you are asked to produce it. Configuring your program and honoring requests that arrive through other channels remains your responsibility, and this is not legal advice.
FAQ
What is an internal Do Not Call list?
It is your own company-specific record of people who asked your business to stop contacting them. It is separate from the National DNC Registry, which is a broad, government-maintained list.
Do I need an internal list if I already scrub the national registry?
Yes. The two are different. Honoring company-specific do-not-call requests is expected regardless of national registry scrubbing, and it can apply even to numbers not on the national list.
How quickly do I have to add someone?
Requests should be recorded and honored promptly. Automating capture so an opt-out immediately writes to the suppression list is the safest way to avoid delay.
How long do internal opt-outs last?
Treat them as indefinite. Unless the person affirmatively opts back in, do not drop old opt-outs to re-contact people.
Should an opt-out apply across channels?
The strongest practice is yes — treat a request to stop as account-wide and cross-channel, so an SMS opt-out also prevents dialer calls. This is safer and matches recipient expectations.
Does Fivra maintain an internal suppression list?
Yes. Fivra suppresses opt-outs automatically and account-wide, screens contacts before messaging, and logs suppression activity to exportable audit logs. It is a tool to support compliance, not a substitute for legal advice.
Outreach at volume. Compliance by default.
Fivra pairs high-volume SMS broadcasting with a built-in power dialer and real-time TCPA & DNC screening — one platform for high-volume teams.
