Why Does ChatGPT Need My Phone Number

ChatGPT has become an internet phenomenon, attracting millions of users every day with its human-like conversational skills. However, one step during the sign-up process causes some hesitation – ChatGPT asks new users for their phone number.

This seemingly intrusive request makes many wonder – why does ChatGPT need your phone number? Is it safe to provide it? Are there alternatives?

In this blog post, we will demystify why does ChatGPT need my phone number and provide insights on the risks, benefits, options and best practices involved.

Why Does ChatGPT Ask For Your Phone Number?

ChatGPT requests new users for their phone number for a couple of key reasons:

1. Identity Verification

Collecting phone numbers helps ChatGPT confirm user identities and prevent creation of fake accounts. This safeguards against misuse by malicious actors.

2. Enhanced Security

By tying accounts to phone numbers, ChatGPT can provide additional account security through measures like login approvals via text message codes.

3. SMS Notifications

ChatGPT may send SMS notifications about features or updates to engaged users if they opt-in. Phone numbers enable this.

So in summary, requesting phone numbers is mainly driven by security, identity verification and functionality considerations according to ChatGPT’s developers.

According to OpenAI, here is how ChatGPT utilizes phone numbers collected from users:

  • Verify user identity by sending a numeric code during sign-up to be entered.
  • Enable login approvals by texting unique codes to confirm user logins.
  • Optionally send SMS notifications about new features and updates (with consent).
  • Track users across devices by linking same phone number.
  • Customer support purposes like account recovery assistance if needed.
  • Analyze usage patterns in aggregate for improving user experience.

OpenAI states phone numbers are not sold or shared, and that data is kept encrypted with restricted internal access. However, risks still exist, as we’ll discuss next.

Is It Safe to Give ChatGPT Your Phone Number?

There are reasonable security and privacy risks to consider before sharing your phone number with ChatGPT:

  • Data breaches – Like any company, OpenAI’s systems could potentially be hacked exposing numbers.
  • Tracking concerns – Phone numbers enable linking together full usage patterns and history across devices.
  • Identification risks – Phone numbers can sometimes be used to identify or trace individuals.
  • Spam risks – Numbers could be misused for sending spammy promotional texts even if unintentionally.
  • Legal risks – Governments may subpoena user data from OpenAI including associated phone numbers.

While OpenAI emphasizes security and restricting employee access, providing any personal data online inevitably carries privacy risks. Users must weigh benefits versus potential downsides.

What Are the Alternatives to Giving ChatGPT Your Phone Number?

If you are uncomfortable sharing your phone number, there are a couple alternatives to consider:

Using Email Address

ChatGPT allows creating accounts with just an email address instead. You lose phone-based security features but gain more privacy.

Disposable Numbers

You can get free or inexpensive temporary “burner” phone numbers to sign up and then discard after if very concerned.

Online Numbers

Sites like Google Voice provide virtual online numbers that forward calls/texts to your real number for added anonymity.

So requiring just an email, disposable number or virtual number does offer more privacy-conscious alternatives to provide access without a personal number.

The Pros and Cons of Giving ChatGPT Your Phone Number

Before deciding whether to provide your phone number to ChatGPT, weigh the key pros and cons:


  • Enhanced account security with two-factor authentication
  • Password recovery assistance if you ever forget login credentials
  • Get important updates from ChatGPT via SMS notifications
  • Seamless usage across multiple devices with linked numbers


  • Privacy risks of personal data exposure through breaches or subpoenas
  • Potential confidentiality issues if number is linked to your identity
  • Receiving unsolicited SMS spam risk
  • Tracking of your activity, usage patterns and history across devices

Evaluating the benefits versus risks helps determine if the added security is worth the tradeoff of providing your personal phone number to use ChatGPT.

ChatGPT requests phone numbers primarily for identity verification, security enhancements and functionality like SMS notifications.

While ChatGPT pledges responsible data practices, sharing any personal data online inherently carries privacy risks that users should consider.

Alternative options like disposable numbers or online phone numbers do allow more privacy-conscious individuals to avoid providing their personal number if desired. Weighing the pros and cons helps determine if the added security of two-factor authentication warrants linking your phone number to safely use ChatGPT.
