DNC screening
How Landing Zone's DNC screening works, what it checks against, and what it cannot tell you about a number.
Do Not Call (DNC) screening checks phone numbers against do-not-call data before you reach out, so numbers that should not be contacted are suppressed instead of dialed or texted.
How screening works in Landing Zone
The DNC & Litigator Scrub tool in Intelligence screens your contacts against two kinds of data in your workspace:
- Your workspace suppression list — numbers suppressed for reasons such as STOP replies, complaints, admin decisions, and internal do-not-call entries.
- Imported DNC data — do-not-call data you have brought into the workspace, including national-list data, which can be imported with proof of the import.
Scrub results show each hit with its reason, and you can export them. See Review screening results for reading the output, and Litigator screening for the companion check against known-litigator lists.
What happens on a hit
When a number matches, it is suppressed for both SMS and calls, and the reason is recorded. Suppressed numbers are excluded by the eligibility checks that run before batches, campaigns, and outbound calls — see Suppression lists.
What DNC screening does not do
DNC screening is not a live query of the federal Do Not Call registry. Landing Zone is not connected to the registry in real time: screening runs only against your workspace suppression list and the DNC data you have imported. If your imported data is missing or stale, a number on the registry can pass your scrub.
Screening also does not make a call or text lawful. A number that passes the scrub is simply absent from the data you screened against — that says nothing about consent, your use case, timing, or any other requirement that applies to the communication.
Your responsibilities
- Source and import current DNC data, and keep it up to date — the scrub is only as good as the data you feed it.
- Pair screening with recorded permission; see Consent and contact permissions.
- Treat a clean scrub as one input, not clearance. Telephone consumer-protection rules and state-level requirements still apply to who you contact and how — see User responsibilities.
