VOIP number checker and risk context
VOIP numbers are common in legitimate and abusive workflows. Treat them as a risk signal, not automatic fraud proof.
Common causes
- High volume signups from unknown VOIP ranges.
- Identity mismatch between caller and profile.
- Repeated support abuse patterns.
How to fix
- Run number check and combine with email/domain trust.
- Apply extra verification for high-risk actions.
- Track repeated abuse indicators.
