Why Factory needs a non-VoIP number
Factory uses SMS verification to confirm real users and reduce automated abuse. VoIP numbers are inexpensive to scale, which is exactly why platforms like Factory block them.
RealNonVoipUSNumber provides genuine non-VoIP USA carrier lines purpose-built for Factory OTP delivery. Your Factory code appears in the dashboard as soon as the carrier delivers the message.
With pay-per-success billing, automatic refunds when no SMS arrives, and 200+ country routes, RealNonVoipUSNumber is built for high-friction apps like Factory.
Factory: VoIP vs real carrier (what sells)
Factory risk engines classify numbers as mobile, landline, or internet telephony. Shared VoIP ranges are cheap to burn and frequently blocked — which is why Factory verification fails on TextNow-style apps.
RealNonVoipUSNumber sells carrier-backed non-VoIP inventory for Factory. Fresh lines per order reduce reuse flags, and pay-per-success billing keeps Factory OTP costs predictable when you scale.
