Call center lead list calculator

For call center managers, outbound sales floors and BPO teams loading purchased, aged or recycled lists into a dialer: estimate how much of the list is still reachable and what the dead numbers cost in agent time or text budget. Every rate is editable; nothing is stored.

Why call center lead lists go bad

  • Purchased and shared lists are often resold, so the same numbers have already been dialed by other buyers and some have since been disconnected.
  • Recycled dialer lists keep numbers from earlier campaigns long after they were last confirmed.
  • Web-form leads can include mistyped or made-up numbers entered just to get past the form.
  • A share of any list is landline or VoIP, which matters if your follow-up runs on SMS.

How to get your real numbers

  1. Pull a random sample of 500 to 1,000 numbers from one list vendor or one campaign.
  2. Validate it against live carrier data (TrueSearch for Business does this in about 30 seconds per 1,000).
  3. Enter the dead, landline and VoIP percentages you get back above.
  4. Repeat per vendor to see which source gives your agents the most reachable numbers.

Questions

Are the default rates typical for call center lists?

No. They are editable placeholders, not call center industry statistics. Rates vary a lot by list vendor, campaign and data age. Validate a sample of your own list and enter what you find.

How should I set list age for a recycled dialer list?

Use the months since the phone number was last confirmed, not since the list was last loaded into the dialer. Numbers that have been cycled through several campaigns can be much older than the current campaign.

Does this check Do Not Call, litigator lists or consent?

No. The calculator only estimates reachability, and TrueSearch for Business checks validity, line type and carrier. It does not scrub against Do Not Call registries or litigator lists, and it does not verify consent. Use the official National Do Not Call Registry (donotcall.gov) and your own consent records for that.

Why do landlines count against texting?

Landlines cannot receive text messages, so every text sent to one is wasted. For calling, a landline can still reach a person, so only dead numbers count as wasted dials.

This guide is general information, not legal advice. TrueSearch for Business checks validity, line type and carrier from licensed telecom data. It does not check the National Do Not Call Registry, state DNC lists or the FCC Reassigned Numbers Database. Not a consumer reporting agency; not for FCRA purposes.
