Profile

Hi HN,I built a phone number validation API after dealing with fake signups, burner numbers, and VoIP abuse in my own projects.What it does: – Strict parsing & normalization to E.164 – Country detection by prefix – Number type detection (mobile / fixed / VoIP / toll-free) – Assigned vs possible prefix checks (NANP and some EU ranges) – Simple heuristics for obvious fake patterns – A single risk score (0–100) instead of binary valid/invalidWhat it intentionally does NOT do: – No SMS sending – No reachability or carrier guarantees – No ML black boxThe goal is to answer a practical question: “Is this number likely to belong to a real person?”Happy to hear feedback.

The company sits in the show hn launch segment, where it competes on its core product or service.

The company is listed at the Show HN launch stage of development.
