Here’s why ChatGPT requires a phone number to use

ChatGPT is very simple to get started on. It’s free to sign up for, and you can either use your own email address or log in with your Google or Microsoft account. But you may have noticed that ChatGPT also asks for your phone number.

Given all the concern over whether ChatGPT is safe to use, that may have thrown you for a loop, which begs the question — why does ChatGPT need your number after all?

Why ChatGPT requires a phone number

Like many things you sign up for online, ChatGPT rightfully requires some proper identification. First, it’s email, which requires you to click the link from within your email to verify. From there, it asks for your name and birth date, followed by a phone number.

This is called two-factor authentication, and it’s common these days, especially since it’s so easy to just create a disposable email address. It should be noted that the phone number doesn’t need to be distinct — more than one email address can be connected to one phone number. OpenAI might be using phone numbers to limit account creation, but I’ve tried setting up two email addresses with a single phone number without issue.

In this case, asking for a phone number is really just about ensuring that you’re a real person and that your account isn’t easily hacked. It should be noted that when logging in, ChatGPT doesn’t require two-factor authentication each time.

Is it safe to give ChatGPT your phone number?

You might be concerned about the idea of giving ChatGPT your phone number or other personal information. The service has been banned in Italy, after all, on the grounds of privacy concerns under the rule of GDPR (General Data Protection Regulation) in Europe.

But those privacy concerns don’t have to do with giving OpenAI your phone number or other personal information. The temporary ban in Italy has more to do with how the large language model was trained, which involves the collection of massive amounts of data. Regulars in Italy claim there is no legal basis for such collection. They also expressed concerns about the lack of age verification when signing up for ChatGPT.

As for the sign-up itself, the phone numbers are only required for “security reasons,” with OpenAI promising not to use your personal information for other purposes in its privacy agreements.

I would not, however, ever give ChatGPT personal information about yourself in the context of chats. Everything you send to ChatGPT is saved, even after you delete it from your chat history. That’s why OpenAI explicitly discourages sharing personal information with the chatbot.

Can I use ChatGPT without a phone number?

Unfortunately no. ChatGPT doesn’t accept VoIP (Voice over Internet Protocol) numbers, which means you’ll need an active mobile number to verify your account. The one exception to this rule is by using an app like Dingtone. The mobile app explains how it can be used to generate a virtual phone number that can be used for accounts like ChatGPT.

There have been reports that if you’re attempting to access ChatGPT in a country where it’s not available, the phone number verification blocks you from moving forward with your account. Of course, using a VPN can get you around the location restrictions, but you’ll still need an active phone number to make it work.

If, for some reason, your phone number verification isn’t working, we’d recommend getting in touch with OpenAI’s support team to help resolve the issue.

One year ago, ChatGPT started a revolution

Exactly one year ago, OpenAI put a simple little web app online called ChatGPT. It wasn't the first publicly available AI chatbot on the internet, and it also wasn't the first large language model. But over the following few months, it would grow into one of the biggest tech phenomenons in recent memory.

Thanks to how precise and natural its language abilities were, people were quick to shout that the sky was falling and that sentient artificial intelligence had arrived to consume us all. Or, the opposite side, which puts its hope for humanity within the walls of OpenAI. The debate between these polar extremes has continued to rage up until today, punctuated by the drama at OpenAI and the series of conspiracy theories that have been proposed as an explanation.
