Why OpenAI blocks VoIP and virtual numbers

OpenAI requires phone verification to limit account creation and prevent abuse. The platform explicitly rejects VoIP numbers—including Google Voice, TextNow, and most virtual number services.

  • •"We couldn't verify your phone number" error on signup
  • •VoIP numbers rejected outright—no code sent
  • •"Phone number already used" when recycled numbers are detected
  • •US numbers have highest success rate, but must be real-SIM

OpenAI states they will not accept VoIP numbers. We provide real-SIM numbers from US carriers, but cannot guarantee acceptance as platforms may change policies.

Bypass OpenAI VoIP blocks with a Real-SIM number

JoltSMS provides real carrier SIM numbers from US mobile networks (T-Mobile/AT&T)—not VoIP. These are treated like normal mobile phones by verification systems.

  • Real carrier SIM numbers—not VoIP or virtual
  • Dedicated to you alone during your rental period
  • Keep the same number for future re-verification and 2FA
  • Team inbox so developers can share access without personal phones

Automate OpenAI verification with the JoltSMS API

Building on the OpenAI API? Use the MCP Server to let your AI agent provision numbers and extract OTP codes autonomously, or call the REST API directly from your ChatGPT plugin or backend service.

MCP Server

Native integration for AI agents. Your Claude, Cursor, or any MCP-compatible client can provision numbers, poll for SMS, and extract OTP codes — no glue code needed.

  • Enable authenticator app 2FA after initial verification for backup access
  • One account per number—OpenAI enforces single-account policy

OpenAI verification FAQ

OpenAI explicitly blocks VoIP numbers, but JoltSMS provides real carrier SIM numbers from US mobile networks. While we can't guarantee acceptance by any platform, real-SIM numbers are significantly more reliable than VoIP alternatives.
