What is E.164 format?
The international standard: a plus sign, the country code and the number, with no spaces, e.g. +14155552671. Store numbers this way and every SMS provider will accept them.
Can you tell if a number is VoIP?
When the number range is assigned to VoIP services we say so. Ported numbers keep their original range, so treat the carrier and line type as strong hints, not proof.
Does this send an SMS or call the number?
No. Validation uses numbering-plan data only; the number is never contacted.
