Requirements

What OpenAI requires from a number

Non-VoIP required
Yes. VoIP ranges are rejected or limited.
Number reuse
A number can verify more than one account over time.

OpenAI rejects VoIP and virtual desk numbers at signup, so the number has to be a real carrier line. Verification is tied to the number itself: a line already attached to an OpenAI account may be refused on a new signup. On a one-time OTP, reusing the same number is free inside the 15-minute window and paid after it expires; a rental or dedicated line keeps the same number for as long as you hold it.

Pair it

The number is half the signal

OpenAI checks the connection alongside the number. A mobile proxy keeps every signup and login on a real carrier IP, so the account you verify here looks consistent from day one.

AI agents

An agent can handle OpenAI verification

Once you create an API key and fund the balance, an AI agent can rent the OpenAI number when you say yes, poll for the message and read the parsed code through VoidMob's open-source MCP server. Works with Claude Code, Codex and other local MCP clients.

Why it works

Verifying OpenAI with a real carrier number

OpenAI no longer asks for a phone number to create a ChatGPT account, but platform.openai.com requires one before issuing your first API key, and it can ask again later. OpenAI does not support landlines, VoIP, Google Voice or premium numbers, so those are refused before a code is sent.

Verification is tied to the number, so a line already attached to an OpenAI account may be refused on a new signup. A one-time OTP covers the initial code, and reuse inside its 15-minute window is free. If the account holds billing or an API key, hold the number.

Losing the number means losing the recovery path. A multi-day rental covers re-verification and tier changes days after signup; the dedicated monthly line is offered per country. Pair either with a stable IP, since OpenAI weighs login network and device signals alongside the number.

FAQ

Frequently Asked Questions

Common questions about OpenAI verification numbers.

Does OpenAI accept virtual numbers for verification?
It accepts real carrier numbers and, by its own help center, does not support landlines, VoIP, Google Voice or premium numbers. The numbers here are non-VoIP carrier lines, which is why the code arrives instead of the step failing at number entry.
Does ChatGPT still require a phone number?
Not for creating a ChatGPT account. OpenAI does require phone verification on platform.openai.com to generate your first API key, and may ask for a number on later account or security steps. The need is real, just narrower than it used to be.
How much does an OpenAI verification number cost?
A one-time OTP for OpenAI/ChatGPT starts at $0.25. Multi-day rentals are priced by term (3, 7, 14 or 30 days). A dedicated monthly non-VoIP line starts at $16.99 per month.
What if the code never arrives?
A one-time OTP is active for 15 minutes. If no message lands in that window the rental auto-cancels and refunds in full, so a failed attempt costs nothing. You can also reuse the same number free of charge inside the window.
Which countries can I get an OpenAI number in?
One-time OTP and rental catalog numbers are US numbers. The dedicated monthly line is the tier offered per country, currently the United States, United Kingdom, Germany, Australia, Hong Kong, Italy and Indonesia.
Can I reuse one number for a second OpenAI account?
Often no. OpenAI ties verification to the number, so a line already attached to an account can be refused on a new signup. Plan on a separate number per account you legitimately own.
Are the OpenAI numbers non-VoIP, and do I need ID?
Yes, every number is a real carrier line rather than VoIP, and no ID is needed: you sign up with a crypto wallet or an email and pay from a crypto-funded balance.
What if the OpenAI code never arrives?
A one-time US number stays active for 15 minutes, and if no code arrives in that window the order cancels itself and refunds in full to your balance.
