Bandwidth is a communications platform and carrier whose APIs include a phone number lookup service. TrueSearch for Business checks every number for validity, line type and carrier, by CSV upload, API or a Claude connector, starting at $97/month with a 7-day free trial. TrueSearch does not check Do Not Call or litigator lists yet.

How to choose
- You want a list cleaned without code. TrueSearch takes a CSV or Excel file, finds the phone column and returns a clean file in about 30 seconds per 1,000 numbers.
- You work inside Claude, ChatGPT or Cursor. TrueSearch connects as an MCP connector, so you can ask the assistant to clean a list.
- You need DNC or litigator scrubbing. TrueSearch does not do this yet. Check whether Bandwidth Number Lookup covers it.
- You run very high volume through an API. Compare per-lookup rates directly against your volume. We do not claim to be the cheapest per lookup.
Upload a CSV or Excel file. Get back every number marked valid or dead, mobile, landline or VoIP, with carrier.
Starter: $97/month for 5,000 numbers after the 7-day trial. Cancel anytime.
Questions
Is TrueSearch cheaper than Bandwidth Number Lookup?
It depends on your volume and how you buy. TrueSearch is a flat $97/month for 5,000 numbers (Starter), with a 7-day free trial. Check Bandwidth Number Lookup's current pricing on their site and compare it against the number of lookups you run each month.
What does TrueSearch return for each number?
Whether the number is valid or dead, its line type (mobile, landline, VoIP or toll-free) and its carrier.
Does TrueSearch check Do Not Call or litigator lists?
No, not yet. If you need DNC or litigator scrubbing, check whether Bandwidth Number Lookup or another provider offers it, or use a dedicated DNC service alongside TrueSearch.
Can I try TrueSearch before paying?
Yes. The Starter plan has a 7-day free trial that covers 250 numbers. Nothing is charged until the trial ends, and you can cancel before then.
