About OpenAI (ChatGPT) verification
OpenAI may ask for a phone number when you sign up for ChatGPT, or when you create an organization or API key on the OpenAI platform, and confirms it with a texted code. OpenAI only serves certain countries and limits how many accounts can share one number, so pick a country where OpenAI's services are available and enter the number as soon as it appears.
Phone verification is a one-off step: afterwards OpenAI signs you in with your email and password or single sign-on, so you won't need this number for normal logins. Turn on multi-factor authentication with an authenticator app for extra protection, and use OpenAI's services in line with its Terms of Use and Usage Policies.
OpenAI (ChatGPT) verification FAQ
Why does OpenAI reject the number?
OpenAI declines numbers from unsupported regions and numbers already used too often. Cancel before any SMS arrives (no charge) and try a different supported country.
Is verification needed for ChatGPT or only for the API?
It depends on OpenAI's current checks: many ChatGPT sign-ups skip it, while API organization setup often asks for it. Buy a number only once OpenAI shows the phone prompt.
Will I need the number to log in later?
Normally not — logins use your email or single sign-on. Keep multi-factor authentication on an authenticator app rather than on this number.
