OpenAI & ChatGPT SMS Verification with a Temporary Virtual Number
A complete walkthrough to pass OpenAI's phone-verification screen when creating a ChatGPT or API account, using a TMPTEL virtual phone number — no SIM card required, available in 150+ countries.
Why use a virtual number for OpenAI?
Protect your real number
Keep your personal SIM out of OpenAI's database and avoid unwanted marketing or leaked-list exposure.
Any supported country
Sign up from a country where OpenAI accepts SMS — US, UK, France, India, Brazil and more.
30-second activation
The virtual number is allocated instantly and OpenAI's SMS typically arrives in under a minute.

Tips for a successful OpenAI verification
- Pick a country where OpenAI is fully available — some regions are restricted and will reject the SMS.
- Request the SMS within 30 seconds of allocating the number; older numbers may already have been used by another OpenAI account.
- If no code arrives, release the number and try another one — you are only charged for successful SMS deliveries.
- Add a backup recovery email in OpenAI immediately after verification: the virtual number expires and cannot recover the account later.
Use responsibly
TMPTEL numbers are intended for legitimate privacy use cases — secondary accounts, API testing, business onboarding. Do not use them to evade OpenAI bans or otherwise breach OpenAI's Terms of Service. See our authorized uses policy.
Frequently asked questions
Can I create a ChatGPT account without a phone number?
OpenAI requires a phone number to activate ChatGPT and the API. A TMPTEL virtual number satisfies the SMS check without exposing your personal SIM.
Will OpenAI accept a virtual number?
Most TMPTEL numbers are accepted by OpenAI. If one is rejected, release it and pick another country — OpenAI's filters vary by region and provider pool.
How long does the OpenAI verification number last?
The number is reserved for around 20 minutes — long enough to complete OpenAI signup. After that, it is recycled and cannot recover the account.
What if OpenAI says the number is already in use?
Release it and try another one — TMPTEL only charges for successful SMS deliveries, so retries are free.
Does this work for the OpenAI API and paid plans?
Yes. The phone check is the same for free ChatGPT accounts, ChatGPT Plus, and the developer platform at platform.openai.com.
