deepidv Phone Verification

Q: What kinds of phone numbers can deepidv verify?

deepidv verifies landline, mobile, VoIP, toll-free, and premium-rate numbers across 211+ countries. For each number we return format validity, line type, carrier, active status, reachability, and a fraud risk score.

Q: How does VoIP and burner phone detection work?

We identify VoIP and temporary number services (Google Voice, Skype, burner apps, etc.) using up-to-date carrier and line-type data. You can choose to block, flag, or accept VoIP numbers based on your fraud tolerance.

Q: Do I need to send an SMS code to verify a number?

No. Basic validation — format, carrier, line type, active status, and risk — runs without sending an SMS. Adding SMS OTP on top provides proof of ownership when you need a stronger guarantee.

Q: Can I verify numbers in bulk?

Yes. In addition to real-time API calls, deepidv supports batch verification for list hygiene — upload phone lists to validate customer databases, clean marketing lists, and append additional data.

Q: How does phone verification help with KYC/AML compliance?

Financial institutions and regulated businesses must verify customer contact information. deepidv's phone verification provides the audit trail, risk scoring, and reachability data required to satisfy KYC/AML obligations.

Real-time phone validation that catches burner numbers, VoIP fraud, and SIM-swap risk before a fake account ever reaches your platform. One API call, every carrier, every country.
