Check phone numbers before onboarding. Invalid numbers and hosted VOIP lines come back as a risk signal that feeds the ALLOW / REVIEW / BLOCK decision, before they enter your ecosystem.

The phone signal joins the other Pre-KYC checks in a single ALLOW / REVIEW / BLOCK decision, so you route the number without parsing raw results.
