DNC Scrubbing: Reduce Outbound Call Complaints

Build a DNC scrubbing process for outbound calls using the National Registry, company suppression lists and opt-out checks, with FCC and FTC sources.

This page is general information, not legal advice. Talk to a qualified attorney about your calling program.

Keep two suppression checks separate

The National Do Not Call Registry and your company-specific do-not-call list address different signals. A number missing from the Registry may still belong to someone who already told your client to stop calling. Review 47 CFR 64.1200(c)-(e) and 16 CFR 310.4(b) for covered calls and exceptions.

The TCPA framework is in 47 U.S.C. 227. The FTC's TSR guide explains that a company-specific stop request overrides an established-business-relationship basis for further covered sales calls. Do not treat a prior purchase as permission to ignore a stop request.

Use current Registry data and retain the check

Federal DNC safe-harbor procedures include using a version of the National Registry obtained no more than 31 days before a call, as well as written procedures, training and compliance records. See 64.1200(c)(2)(i) and 310.4(b)(3). The 31-day check does not, by itself, establish a complete safe harbor or permission to call.

Our operational recommendation is to check suppression when a record enters a list and again before a campaign can dial it. Save the check date, data version, matching result and any legally reviewed exception. If your data is stale or the check fails, hold the campaign until the team resolves it.

Record a company-specific stop request immediately

Under 64.1200(d), covered callers need a written DNC policy and trained personnel. Record the request when received and honor it within a reasonable time, no more than ten business days. The FCC requires honoring the request for five years. That period is not a recommendation to resume calling later; review the current legal basis and other applicable rules first.

Our recommended process is immediate suppression. Train staff to recognize ordinary language such as a request not to call again. Keep a complaint workflow that records the number, client or seller, request time and action taken. Limit access to this information to the people maintaining the calling program.

To test an internal suppression file offline, use the internal DNC scrub in James Hill's free MIT TCPA checklist starter as a development aid, not National Registry access or legal advice.

Test imports, duplicate records and list overrides

A daily import can recreate a contact that was removed yesterday. A second list can expose a suppression setting that the first list respected. As a practical test, use a team-owned number with a stop flag, import it twice and try every list configuration that could reach it. Confirm behavior before putting consumer records into the workflow.

RizzDial's security page documents contact-level DNC flags, opt-in tracking, consent documentation and opt-out handling tools. It explicitly warns that list settings can override contact flags. Audit those overrides. The page does not establish automatic National Registry scrubbing, so confirm how your team will perform that check rather than assuming it is included.

Scrubbing does not replace other call checks

Review the calling hours and consent checklist before launch. For predictive dialing, the FCC limits covered abandonment to 3% of live-answered calls per campaign in each 30-day measurement period or shorter remaining portion; see 64.1200(a)(7). The TSR abandonment safe harbor includes additional conditions. Removing DNC matches does not address pacing or agent availability.

The TSR also requires transmission of caller ID information under 310.4(a)(8). Our practical check is to call a team-owned number and then return the call to the displayed number. Confirm that the identity and callback handling match the seller.

Respond to a complaint with evidence

Pause the affected workflow while reviewing the consent record, Registry check, company suppression history and dialer settings. Determine whether the same error affects other lists. Document the correction and repeat the test before restarting. These are operating recommendations, not a guarantee against complaints or liability.

For changes to revocation scope, review the limited waiver in FCC DA 26-12, January 6, 2026 and the current rule with counsel. The waiver is not permission to ignore stop requests.

Plan your dialing workflow

Read the TCPA compliant dialer guide, the calling hours and consent checklist, and the DNC scrubbing workflow. Compare RizzDial vs Kixie and RizzDial vs Readymode against the same team requirements.

FAQ

Is National DNC scrubbing the same as an internal do-not-call list?

No. The Registry and company-specific stop requests are separate checks. A number can be absent from the Registry and still be suppressed for your company.

How recent should the Registry data be?

The federal DNC safe-harbor procedures include use of a Registry version obtained no more than 31 days before the call. Written procedures, training and records also matter.

Does RizzDial document automatic National Registry scrubbing?

The security page documents contact-level DNC flags and consent tools. It does not establish automatic National Registry scrubbing. Confirm the scrubbing workflow before launch.

Can a list setting affect a contact's DNC flag in RizzDial?

Yes. RizzDial's security page warns that list settings can override contact-level DNC flags. Review and test each list configuration.
