Openai SMS VERIFICATION Receive the Openai code on a rented number.

OpenAI has asked for a phone number at different points over the years. For a long stretch every new ChatGPT account needed one, and today many sign-ups finish with only an email, while the API platform and some account actions can still ask for a number before they continue. When the prompt appears, a rented number takes the code without putting a personal line on an account used for work experiments.

OpenAI limits how many accounts one number can verify, and it refuses VoIP numbers at that step. The numbers here come from real mobile carrier ranges and are used for one activation, which suits the check. A number changes nothing about which countries OpenAI serves, and its supported-countries list still applies to where you use the service.

Where the phone step appears

OpenAI shows the phone prompt after the email is confirmed, when it wants more assurance that a real person is behind the account. On the API platform the prompt can appear before the first key is created or before free credits are granted. Sign-in with Google, Microsoft or Apple sometimes skips the step, since those providers already verified the person.

The code arrives by SMS, sometimes with a WhatsApp option. A rented number receives SMS, so choose that route. If the code does not come within the window, the activation refunds, and a number from another country can be tried.

Accounts for work, testing and teams

Developers often keep an API account for a client project apart from their personal ChatGPT account, so usage and billing stay separate. QA engineers test sign-up and onboarding flows of products built on OpenAI. Teams can instead use OpenAI's organization and project features, which let several people share billing without each creating a new account.

OpenAI's usage policies apply per person and per organization. Creating accounts to get around a suspension or rate limits breaks those policies, and OpenAI links accounts by payment details and usage patterns as well as phone numbers. Read our acceptable use policy too.

Keeping the account after the activation ends

Turn on multi-factor authentication in the account security settings, using an authenticator app. OpenAI then asks for the app code at sign-in, and the rented number plays no further part in logging in.

Billing, API keys and organization membership are all tied to the account and its email. If OpenAI asks for a phone again in the future, for example after a policy change, rent a number at that point. Prices per country are on the pricing page.
