NumTrue checks if a phone number is actually live, dead, or disposable, using real HLR/MNP carrier lookups, not regex format-checking. Most "validators" just check format and call a disconnected number valid; NumTrue queries the real carrier network for live/dead status, ported carrier, and disposable/burner detection. Bulk CSV upload or REST API. Pay-as-you-go credits, no subscription, never expire. From $9 for 1,000 lookups, 10 free to start.

Hey Product Hunt 👋 I built NumTrue because I kept seeing the same problem: teams paying to text or call numbers that have been dead for months, because format-only "validators" happily say a disconnected number is valid. NumTrue does real HLR/MNP lookups instead, the same carrier-network queries telecoms use, so you actually know if a number is live, dead, ported, or a disposable/burner number before you spend anything on it. No subscription, credits never expire, 10 free credits to try it right now. Would love your feedback, especially if you're validating leads/lists for sales or marketing, that's exactly who I built this for.

Plugged in a few sketchy numbers from my old contact list and the results were brutally honest, flagged two burners I never would have caught. The bulk CSV option is a nice touch if you need to clean a list fast.
