Why Cofix needs a non-VoIP number
Cofix uses SMS verification to confirm real users and reduce automated abuse. VoIP numbers are inexpensive to scale, which is exactly why platforms like Cofix block them.
RealNonVoipUSNumber provides genuine non-VoIP USA carrier lines purpose-built for Cofix OTP delivery. Your Cofix 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 Cofix.
Cofix: VoIP vs real carrier (what sells)
Cofix risk engines classify numbers as mobile, landline, or internet telephony. Shared VoIP ranges are cheap to burn and frequently blocked — which is why Cofix verification fails on TextNow-style apps.
RealNonVoipUSNumber sells carrier-backed non-VoIP inventory for Cofix. Fresh lines per order reduce reuse flags, and pay-per-success billing keeps Cofix OTP costs predictable when you scale.
