ChatGPT Phone Verification: When It's Required and What to Do If the Code Doesn't Arrive

When you use OpenAI services, you may sometimes be asked to verify your phone number. This step isn't shown to every user or in every situation, however, and OpenAI's policies can change over time. Running into this screen can be confusing, especially when you're creating a new account or starting to use developer tools. In this guide, we explain when you might see the ChatGPT phone verification screen, what to check if the code doesn't arrive, and how to protect the privacy of your number.

Is ChatGPT phone verification always required?

No, it isn't always required. Many users can access ChatGPT by signing in with an email address or with a Google, Microsoft or Apple account without providing a phone number. That said, you may be asked for phone verification in situations like these:

• When creating a new account in some regions or during certain periods;
• During some actions on the API platform for developers, such as creating an API key;
• As an extra security check when unusual activity is detected on the account.

This list isn't definitive. OpenAI may update its verification requirements for security and abuse-prevention reasons, so it's always best to follow the current instructions on the screen in front of you.

How the phone verification steps work

1. Select your country code on the verification screen.
2. Enter your phone number without any leading zero that you would normally dial domestically in your country.
3. Wait for the one-time code to arrive and type it into the field on screen.
4. Codes are only valid for a limited time, so use the code as soon as you receive it.

In some cases, you may be offered the option to receive the code through a channel other than SMS. Read the options on screen carefully before completing the process. The number you verify is associated with your account and may be used again in future security checks, so choosing a number you'll have long-term access to helps you avoid problems later.

What to do if the verification code doesn't arrive

A code that never arrives is a very common problem, and it usually has a simple cause:

• Number format: Make sure you selected the correct country code and entered the full number.
• Too many attempts: Requesting codes repeatedly in a short time can trigger a temporary limit. Wait a few minutes before trying again.
• Number usage limit: If the same number has already been used on a certain number of accounts, it may not be accepted again.
• Number type: Some platforms may not support landlines, VoIP numbers or certain types of virtual numbers.
• Carrier and device settings: If you're using your personal line, check for SMS blocking, spam filters or restrictions on texts sent from abroad.

If the problem continues, trying a different browser or device, temporarily disabling browser extensions and checking your internet connection can also help. If verification still won't complete after all of this, the most reliable path is to follow the current guidance in the OpenAI Help Center.

Personal number or virtual number?

What to know before verifying with a virtual number

If you'd rather not share your personal number, you could consider using a temporary number from OnaySIM. Before buying one, check the service list on the get a number page to see whether there's an option for the service you need. The process works like this: you choose a service and a country, enter the number you're given on the verification screen, and the incoming code appears in the "Active Codes" section of your dashboard. The number is reserved for about 20 minutes; if no code arrives in that time, the order is canceled and the charge is refunded to your balance.

Still, keep these points in mind:

• Acceptance isn't guaranteed: OpenAI may not accept some number types for verification. In that case, you may need to use your own permanent number.
• The number is temporary: You may not be able to access the same number again after verification. For an account with a paid subscription or important data, using a permanent number is safer.
• Follow the Terms of Use: OpenAI's terms prohibit trying to get around usage limits or restrictions and impersonating other people. Use a virtual number only for legitimate purposes such as protecting your privacy.

If you're a developer testing your own product's SMS verification flow, check the API documentation for our setup that's compatible with common SMS activation APIs, and see our SMS verification testing guide for a complete test plan.

Account security and privacy tips

• Turn on multi-factor authentication in the security section of your ChatGPT settings and use an authenticator app.
• Store the recovery code you're given in a safe place.
• Use the session options in your security settings to log out of devices you don't recognize or no longer use.
• Choose a strong password that you use only for this account; if you sign in with a social login, secure the linked Google, Microsoft or Apple account as well.
• Avoid sharing sensitive personal data, such as ID numbers or bank details, in your chats.
• Never share your verification code with anyone; messages asking for a code are usually account takeover attempts.

Conclusion

ChatGPT phone verification isn't required of every user; whether you see it depends on your account type, your region and OpenAI's current policies. When verification is requested, checking the number format, avoiding repeated attempts and, if needed, waiting a few minutes before trying again solves most problems. If you use a virtual number, remember that it's temporary and that a permanent number plus multi-factor authentication is the safer choice for important accounts.
