No mobile phone number is required for ChatGPT registration? This article will explain in detail the latest changes in the ChatGPT registration process, including the advantages of no longer mandatory mobile phone numbers, as well as scenarios where mobile phone number authentication is still required in special circumstances such as API usage and multi-account creation. In addition, we will also discuss the security of mobile phone number registration and provide solutions to common errors during the registration process.

ChatGPT registration: Mobile phone number is no longer required

In the past, registering for ChatGPT required mobile phone number verification. But an update in December 2023 canceled the requirement . Now, you can easily register for ChatGPT by simply having an email address or Google, Microsoft, or Apple account.

It should be noted that although there is no need for mobile phone number verification, ChatGPT still has an age limit . According to regulations, users over 13 years old are only allowed to use, and users under 18 years old must obtain the permission of their guardian or agent.

ChatGPT API usage: Mobile phone number is still necessary

Although ChatGPT itself does not require a mobile phone number, using the ChatGPT API still requires providing a mobile phone number for verification . This is due to security reasons, and there is currently no way to bypass the mobile phone number registration API.

Are landlines, Google Voice or virtual number (VoIP) available?

Currently, ChatGPT's mobile phone number verification only supports landline phones and mobile operators' numbers , and does not support Google Voice or VoIP virtual numbers. The verification code will be sent via SMS and does not support voice or email verification.

Can a mobile phone number be used for multiple accounts?

Although API usage requires a mobile phone number, a mobile phone number can be used for up to three OpenAI accounts . Even if the account is unbind or deleted, the number of times the mobile phone number has been used will not decrease, and the total is still limited to 3 times. Please note that only accounts that complete mobile phone number verification for the first time can obtain the API's free credit (free token) .

Is it safe to register a mobile phone number?

OpenAI attaches great importance to user privacy and promises to use mobile phone numbers only for account verification and platform security, and will not use them for other purposes.

Although the data entered into ChatGPT may be used for model training, this is limited to conversational data, not registered personal information. Given the user size of ChatGPT and the enterprise size of OpenAI, the risk of mobile phone numbers being abused is low.

Solutions for errors in mobile phone number registration

Here are some common errors and solutions:
