How ChatGPT checks your number

ChatGPT is made by OpenAI. OpenAI may ask for a phone number when you sign up, or later when you set up its developer platform to get API keys. Not every sign-up gets asked.

When it does ask, you type the number and OpenAI sends a short code by text. You enter it on the next screen and the check is done.

OpenAI only accepts numbers from countries where it offers its service. It also limits how many accounts one number can verify, so a number that has been used before may be refused.

Why use a one-time number

ChatGPT's phone check is usually a one-time gate. Once your account is confirmed, everyday sign-in normally goes through your email, or a Google, Apple or Microsoft login, not a text. That makes a one-time number a good fit here.

Often works

OpenAI accepts many numbers but refuses some, especially from countries it does not serve. A refused number is refunded, so a failed try only costs you a few minutes.

How to get your ChatGPT code

  1. 1

    Top up with crypto

    Add a balance with Bitcoin, USDT, Monero or another coin. No card, no email, no ID.

  2. 2

    Pick a country

    Choose where the number should be from. The ChatGPT price shows before you pay.

  3. 3

    Enter the number

    Type the number into ChatGPT and ask for the code. It appears on your order page, usually within a minute or two.

The number stays active for about 15 minutes. If no code comes, the full amount goes back to your balance automatically.

Picking a country

Pick a country where ChatGPT is available, since OpenAI turns down numbers from places it does not serve. If you use a VPN, a number from the same country can help everything line up. If one country fails, try another one from the list.

If the code does not arrive

OpenAI says the number is not supported

This usually points to a country OpenAI does not serve, or a number it will not take. The refund is automatic, so switch to a different country.

It says the number is already in use

OpenAI caps how many accounts one number can confirm. Get a new number. If the first one never received a code, its cost is already back in your balance.

A digit went missing

OpenAI's box expects the full number with the country code. Copy it straight from your order page so nothing gets dropped.

The code is slow

Wait a minute or two, then ask OpenAI to resend. You have about 15 minutes, and a number that never gets a code costs you nothing in the end.

One code, or a number you keep?

Honest advice

OpenAI may ask for a phone check again later, for example on the developer platform. For an account you plan to run for years, like one a business depends on, a number you keep is the safer buy. See numbers you keep.

Need it for longer?

Keep a number for ChatGPT for a day, a week or a month. Every ChatGPT code it gets in that time shows up on your order page and in Telegram, so you can log in again later. You can extend it before it ends.

ChatGPT SMS code: FAQ

Does ChatGPT always ask for a phone number?+

No. Lots of people sign up with just an email. OpenAI asks for a phone on some sign-ups and for some API features.

Can I use this for the OpenAI API too?+

Yes. The developer platform runs on the same OpenAI account, so the same kind of phone code works there.

Will I need the number to log in later?+

Normally no. You log in with your email or with Google, Apple or Microsoft. If OpenAI does ask for the phone again, a one-time number cannot receive that, so think about a number you keep.

Why was my number refused?+

OpenAI blocks numbers from countries where ChatGPT is not offered, and it limits how many accounts can share one number. Try another country, and know that the failed order is refunded.

What if the ChatGPT code never comes through?+

Once about 15 minutes pass with no code, SimVala puts the full price back on your balance by itself.

Does SimVala need my email?+

No. Your SimVala account is just a private account number, and you fund it with crypto.
