Phone line type detection: is a number mobile, landline, VoIP, toll-free, or premium rate, and can it likely receive SMS. Classifies from the national numbering plan and flags numbers whose plan does not separate mobile from fixed lines (US, Canada) as ambiguous instead of guessing. For SMS routing, lead scoring and fraud screening. Not a live carrier lookup. Keyless.
