Countries, VoIP and virtual numbers Phone verification · About 4 minutes · Updated 2026-11-09 OpenAI only accepts mobile numbers from the countries and regions it supports. Numbers from places such as mainland China, Hong Kong or Russia get no text, and landlines, Google Voice and other VoIP numbers are refused everywhere. - Numbers from unsupported countries can't receive OpenAI's texts, wherever you are. - OpenAI's Help Center says landlines, premium numbers, Google Voice and other VoIP numbers aren't supported. - You can't unlink a number from an account yourself, so verify with a number you'll still be able to read when you need it. ## Does your country's number work? Only if your country or region is on OpenAI's supported list. Phone verification texts mobile numbers in those places only; mainland China, Hong Kong and Russia, among others, are not on it. If your country is missing from the list on the verification page, or nothing arrives, the number itself is fine; OpenAI just doesn't text it. Signing up for ChatGPT on the web often needs only an email. Where people actually get stuck is a phone check: signing in to Codex, or creating a first API key. [OpenAI Help Center: ChatGPT supported countries](https://help.openai.com/en/articles/7947663-chatgpt-supported-countries) ## Numbers OpenAI refuses | Number | Why it fails | | --- | --- | | Numbers from unsupported countries | The page can't text them. | | Landlines | Not supported, per the Help Center. | | Premium numbers | Not supported, per the Help Center. | | Google Voice and other VoIP numbers | Not supported, per the Help Center; internet phone numbers are usually detected. | | A number that verified other accounts | Numbers have a usage limit, so a used one may show as already in use. | [OpenAI Help Center: Can I use a premium number, landline, Google Voice, or other VoIP phone number?](https://help.openai.com/en/articles/8983024-can-i-use-a-premium-number-landline-google-voice-or-other-voip-phone-number) ## How many accounts can one number verify? OpenAI words it differently by product. For the first API key on the developer platform, the Help Center says one number can verify up to 3 accounts, and deleting an account doesn't give that back. For ChatGPT, it says a phone number can't be unlinked from an existing account, and a normally deleted account's number is removed from its systems after 30 days. The safe rule is one number for one account. Verifying several accounts with one number can hit the limit and tends to get accounts flagged.

Your options To get past one Codex or ChatGPT check, a paid number is the least effort. Pay2GPT's Codex login number is a US +1 number on a physical SIM, $3.49 per number, valid for 21 days, with the code shown on your order page, swaps if nothing arrives and a refund if none of your numbers gets a text. | Option | Upside | Catch | | --- | --- | --- | | Your own SIM or eSIM in a supported country | The number stays yours for later checks | Costs the most to get and keep active | | A friend's or relative's number | Free | Not yours, so the next check means asking again | | Free public SMS sites | Free | Shared, mostly refused, and anyone can read the code | | A paid verification number on a physical SIM | Ready in minutes; swap or refund if nothing arrives | It expires, then it's no longer yours | [Codex login number: a US number →](https://pay2gpt.com/en/codex-sms) [Choosing an SMS verification service →](https://pay2gpt.com/en/guide/sms-verification-service.md) ## After verifying - Once the account is verified, everyday ChatGPT use doesn't need the number. - A new device or network may ask again; within the number's validity, open your order page to read the code. - To get Plus or Pro, Pay2GPT activates it on your own account after payment, with no overseas card and no phone number needed.

Usually not; an email is enough. A phone check comes up for Codex sign-in, a first API key, or some security checks. ### Can I use a Google Voice number? No. OpenAI's Help Center says Google Voice and other VoIP numbers aren't supported. ### Can I unlink a verified number? Not yourself. The Help Center says a number can't be unlinked from an existing account; after a normal deletion, the number is removed after 30 days. ### Will a number from an unsupported country work over a VPN? No. What matters is the number's country, not your connection; OpenAI only texts numbers in supported countries. ## Related guides - [Codex asks you to verify a phone number?
