Every disconnected or invalid number you dial hurts your pool reputation and wastes agent time. Pre-dial scoring removes the dead weight before it enters your queue.
A list full of disconnected numbers does more than waste agent time — it tanks your DID reputation. Reputation engines watch pattern of calls to dead numbers and flag the caller as suspicious. Clean lists protect your pool.
Identify numbers that are no longer in service before your dialer connects. Removes the biggest single drag on answer rate.
Format validation and carrier lookup catch typos, fake numbers, and never-assigned ranges that will always fail.
Distinguish mobile, landline, and VoIP. Match calling strategy to line type — VoIP numbers often have lower answer rates on outbound campaigns.
Check against the FCC Reassigned Numbers Database. Calling a reassigned number is a known TCPA liability trigger.
Partner integrations return a predictive score based on recent activity signals — which numbers are currently likely to answer.
Optional integration with litigator lists to flag serial TCPA filers before they enter your dialer.
Basic pre-dial filtering is built into every account. Real-time disconnect detection, carrier lookups, and line-type identification require no additional setup or cost. Numbers with known-bad dispositions from prior calls are automatically excluded.
Full answer-probability scoring requires a partner integration. Services like DialRight, Twilio Lookup, and Numeracle score each number based on recent activity signals — whether the number has answered calls recently, whether it is currently active on a carrier network, and more.
Three steps from baseline to operational.
Submit lead lists via API or dashboard upload before they enter the dialer.
Each number is validated, line-type detected, and optionally scored for answer probability.
Only numbers that pass filtering enter the dialer queue. Flagged numbers are returned with reasons.
The cost of cleaning a list is almost always less than the cost of dialing through the dirt in it.
