If you want to use ChatGPT, you need to create an account. During the account creation process, you will be asked to verify your phone number. This can raise questions in users’ minds for various reasons. We have prepared an article explaining why ChatGPT requires phone number verification.
Why does ChatGPT ask for a phone number?

ChatGPT asks for phone verification as part of its security measures. Verifying your phone number is necessary to confirm your account and ensure the platform remains secure.
In order to finalize the creation of your ChatGPT account, you will be prompted to provide phone number verification. Without this verification, the platform may accept a large number of fake users, leading to unnecessary usage and ChatGPT being unable to respond to real user requests. Therefore, phone verification is required to maintain the security and legitimacy of the platform.
We have compiled a list of some aspects of why ChatGPT needs a phone number below:
1. Enhancing User Security
Phone verification plays a vital role in enhancing user security. By associating a phone number with each ChatGPT account, OpenAI can implement measures to safeguard user data and prevent unauthorized access. This additional layer of security protects users from potential privacy breaches and ensures their information remains confidential.
2. Limiting Misuse and Abuse
Phone verification helps to limit the misuse and bad behavior of ChatGPT. Since anyone with internet access can use it, some people might try to use it for bad things. Asking for a phone number during registration makes them think twice before misusing the system. It encourages responsible use and discourages those with bad intentions.
3. Reducing Spam and Fake Accounts
By using phone verification, ChatGPT can reduce spam and fake accounts. Sometimes, there are accounts that send unwanted messages or bots that flood the system. When you provide your phone number, it helps filter out spam and fake behavior. This ensures that you have a better experience and receive accurate responses.
4. Following the Rules of the Community
ChatGPT wants everyone to follow the rules and have a good experience. Phone verification helps them identify and track accounts that don’t follow the rules. When they find those accounts, they take action to make sure the platform is safe and respectful for all users.
5. One account per person
Requiring a phone number during registration makes sure that one person can only have one account. This helps keep things fair and ensures that everyone has their own unique account linked to their identity. It also maintains the trustworthiness of the ChatGPT platform.
Is it safe to provide my phone number to ChatGPT?

According to ChatGPT’s statement, phone numbers are only used for account verification purposes, and they take privacy very seriously. They don’t use your phone number for any other purposes but for security reasons. Users should evaluate whether to provide their phone number to ChatGPT based on the platform’s reputation for security.
Can I use ChatGPT without providing my phone number?
You cannot access or use ChatGPT without verifying your phone number. The signing-up process of ChatGPT requires you to verify your phone number.
Additionally, VoIP (Voice over Internet Protocol) numbers are not accepted, so an active mobile number is required to verify your account.
Can I use my phone number for multiple accounts?
You can use the same phone number to verify a maximum of two different accounts.
Can I unlink my phone number after creating a ChatGPT account?
At the moment, once you have confirmed your phone number, you cannot remove or change the phone number information associated with your account. However, if you have concerns about your phone number, you can delete your ChatGPT account at any time.
