CheckHim: Real-Time Phone Number Verification for Developers
CheckHim is a developer-focused platform for real-time phone number verification.
We help teams reduce delivery failures, filter out invalid or unreachable numbers, and improve messaging and onboarding funnels.
What We Do
- Instant validation – format, carrier, line type, and deliverability indicators
- Fast global response times – resilient infrastructure with low latency
- Actionable metadata – for routing and risk decisions
- Transparent API design – consistent error semantics, no surprises
Why We Built It
Too many workflows rely on unverified numbers, wasting SMS, voice, and operational costs.
CheckHim provides a lightweight, modern API so you can decide early whether a number is worth contacting.
Reliability & Privacy
- Performance – caching layers, regional routing, and graceful degradation (targeting p95 latency under 100 ms in common regions)
- Privacy – numbers are processed transiently and never enriched with unrelated personal data
🛠️ Developer Experience
- Clear documentation, sandbox responses, and deterministic test numbers
- Safe key rotation, environment segmentation (test vs. live), and real-time usage monitoring
Roadmap Highlights
- Expanded carrier reach & region coverage
- Bulk asynchronous verification endpoints
- Webhooks for status-lifecycle changes
- Optional advanced risk scoring
- At this moment we are only available in some countries (Brazil, Angola, USA, France, Israel, China, Nigeria, South Africa, Portugal, Kenya and UK)
