Why A23 needs a non-VoIP number
A23 uses SMS verification to confirm real users and reduce automated abuse. VoIP numbers are inexpensive to scale, which is exactly why platforms like A23 block them.

With pay-per-success billing, automatic refunds when no SMS arrives, and 200+ country routes, RealNonVoipUSNumber is built for high-friction apps like A23.
A23: VoIP vs real carrier (what sells)
A23 risk engines classify numbers as mobile, landline, or internet telephony. Shared VoIP ranges are cheap to burn and frequently blocked — which is why A23 verification fails on TextNow-style apps.
RealNonVoipUSNumber sells carrier-backed non-VoIP inventory for A23. Fresh lines per order reduce reuse flags, and pay-per-success billing keeps A23 OTP costs predictable when you scale.
