Bulk Phone Number Validator
Upload thousands of numbers at once. NumTrue validates reachability, carrier, line type, and disposable status in bulk, so you only pay for results that matter.
Three steps to a clean list
1. Upload your list
CSV, Excel, or paste numbers. We auto-detect country and format.
2. Real-time HLR lookup
Each number is queried directly against the carrier network, not a stale database.
3. Export & act
Download CSV with full results. Filter by status, type, or carrier instantly.
What every lookup tells you
Live reachability
Is the number active and reachable right now? Not cached, real-time.
Current carrier
Which operator currently serves the number, including ported networks.
Line type
Mobile, landline, VoIP, toll-free, or data SIM, know what you're dialing.
Disposable detection
Flag temporary and burner numbers before they waste your credits.
Country & MCC/MNC
Full network identification for international routing.
CSV export
Download filtered results: live mobiles, dead numbers, or full dataset.
