How to Scrub a List Against DNC

How to do it

1. 1

   Confirm the call is telemarketing

   DNC rules target telemarketing. Purely informational or transactional calls, and some calls under an established business relationship or with prior express written consent, are treated differently. Classify the campaign first, because it decides which numbers you must remove and which exemptions you can rely on.

2. 2

   Register for access to the National Registry

   Sellers and telemarketers access the registry through telemarketing.donotcall.gov and pay a per-area-code fee for the data (the first five area codes are free). You need a Subscription Account Number before you can download the numbers to scrub against.

3. 3

   Assemble and normalize your list

   Gather the numbers you intend to call and put them all in a consistent format, ideally E.164, so the match is exact. A list with mixed formats will silently fail to match a chunk of registered numbers and leave you calling people you should have removed.

4. 4

   Match against the national registry

   Run your list against the downloaded registry data and remove every hit, unless a documented exemption clearly applies to that number. When in doubt, suppress: the cost of removing a callable number is far lower than the penalty for dialing a registered one.

5. 5

   Layer in state DNC registries

   Several states maintain their own do-not-call lists with their own rules, and some cover call types the federal list does not. If you call into those states, scrub against their registries too, because state obligations stack on top of the federal ones.

6. 6

   Apply your internal do-not-call list

   Separate from any government registry, you must keep and honor a list of people who told your company specifically to stop calling. An internal opt-out overrides an established business relationship, so a past customer who said 'stop' stays suppressed regardless of the national list.

7. 7

   Re-scrub at least every 31 days

   The registry updates constantly and your list keeps changing, so a one-time scrub goes stale fast. Re-running the match on at least a 31-day cadence is both the FTC's expectation and the practical way to avoid dialing a number that was added last week.

8. 8

   Document every scrub

   Keep records of when you scrubbed, which registries you used, and which numbers you removed. In a complaint the burden is on you to show a routine, good-faith compliance process, and dated scrub logs are the evidence that demonstrates it.

Common gotchas

• Scrubbing once and never re-running it, when the FTC expects a re-scrub at least every 31 days.
• Scrubbing only the national registry and ignoring state DNC lists that cover your calls.
• Forgetting the internal suppression list, which overrides an established business relationship and must be honored.
• Storing numbers in mixed formats, so the match misses registered numbers and you dial them anyway.
• Assuming registered numbers eventually drop off, when registrations are permanent and never expire.
• Keeping no scrub records, so you cannot show a good-faith compliance process if a complaint lands.

Where Topcalls fits

Topcalls builds DNC hygiene into the calling flow at $0.35/min, all-inclusive, so scrubbing is not a separate bill on top of telephony. Lists can be checked against do-not-call data and your own suppression list before the first dial, and every call is recorded and transcribed, which gives you the dated audit trail regulators expect. The per-minute rate covers the voice model, telephony, recording, transcription, and analytics with no add-on fees, so compliance tooling and dialing sit in one product. Topcalls provides the controls; you still own the legal judgment about which numbers you may call, so treat this as tooling, not legal advice.
