How to Sign Up for ChatGPT Without Your Phone Number

Posted on 25/05/26 12:00 pm

OpenAI asks for phone verification for a real reason — but that doesn't mean it has to be your personal number. Here's what actually works in 2026.

You go to sign up for ChatGPT and hit the phone verification step. Maybe you'd rather not hand OpenAI your personal number. Maybe you're setting up a second account for a specific project. Maybe you're in a country where the SMS just never seems to arrive. Whatever the reason — you're not alone, and there are legitimate ways around it.

Just want the quick fix? Get a non-VoIP number, receive the code in under a minute.

But if you want to know why certain methods fail — and save yourself from burning time on things that don't work — it's worth reading a bit further.

Why OpenAI asks for your number in the first place

It's not about marketing. OpenAI uses phone verification as a basic spam deterrent — each number can only verify a limited number of accounts, which makes it expensive to create thousands of fake accounts for abuse. That's the whole reason.

The side effect is that it catches real people who just don't want to hand their personal number to another tech company. Which is a reasonable thing to not want. Your phone number is tied to your identity in ways that an email address isn't — it can be used to look up your name, location, and carrier, and once it's in a data breach it's there permanently.

What doesn't work (save yourself the frustration)

VoIP numbers — the kind you get from Google Voice, Skype, or most free apps — get rejected by OpenAI almost immediately. They've built detection specifically for these because they're the first thing spammers try. If you've already tried a Google Voice number and got an error saying the number isn't supported, that's why.

Free temporary number websites work occasionally but they're unreliable. The numbers are shared publicly, which means someone else might have already used that number for an OpenAI account. You'll get the "number already in use" error and have no way to know until you've already tried.

Quick note: OpenAI also blocks numbers from certain countries entirely, regardless of how you're accessing the site. If you're getting a regional restriction error, you'll need a number from a supported country — a US or UK number usually works.

What actually works: a real non-VoIP virtual number

The solution that consistently works is a virtual number that runs on a real carrier — not VoIP, not a shared free pool, but an actual SIM-backed number from a supported country.

This is exactly what SMS Pin Verify provides. The numbers are non-VoIP, which is the key thing OpenAI checks for. You pick a number, OpenAI sends the verification SMS to it, you see the code in the dashboard, and you're done. The whole thing takes about two minutes.

Non-VoIP means the number is registered with a real mobile carrier, not an internet phone service. OpenAI specifically checks for this — it's why carrier-based virtual numbers work when Google Voice doesn't.

Step by step

  • STEP 1: Go to smspinverify.com and create an account. Top up a small balance — ChatGPT verification numbers are on the cheaper end.
  • STEP 2: Search for ChatGPT or OpenAI in the service list and select a US number (US numbers have the highest success rate with OpenAI).
  • STEP 3: Go to chat.openai.com, start the sign-up, and when you reach the phone verification step — enter the number you just got.
  • STEP 4: Head back to your SMS Pin Verify dashboard. The verification code from OpenAI will appear there within a few seconds. Copy it and enter it on the ChatGPT page.
  • STEP 5: That's it. Your account is verified and you never had to touch your personal number.

A few things worth knowing before you start

Numbers are single-use for verification. Once a number has been used to verify a ChatGPT account, OpenAI won't accept it for another one — this is OpenAI's restriction, not the service's. So if you're planning to create multiple accounts, you'll need a separate number for each.

The code usually arrives within 30 seconds. If it doesn't show up after a minute, don't keep hammering the "resend" button — wait the full countdown, then try once more. If it still doesn't come through, grab a different number and try again. It's rare but it happens.

US numbers work most reliably. UK numbers are a solid second choice. Some other countries work too, but if you want to avoid any friction, start with a US number.

Is this against ChatGPT's rules?

Using a virtual number to verify an account isn't against OpenAI's terms of service. What their terms prohibit is creating accounts specifically to bypass safety systems or abuse the platform. Signing up with a virtual number because you'd rather not share your personal one is no different from using a secondary email address — which nobody considers a violation.

Millions of people do this for privacy reasons alone, and it's completely legal in pretty much every country.

If you run into any trouble — a number not working, the code not arriving — SMS Pin Verify's support is reachable on WhatsApp and Telegram, and they're pretty quick to respond. Sometimes it's as simple as trying a different number from the list.
