A number for ChatGPT and Claude: passing the phone check
OpenAI and Anthropic ask for a phone at sign-up. A virtual number works for that — if you pick the right country.
Why they want a phone
The phone check protects both services from mass sign-ups. The number is confirmed with one SMS code — after that you don't need it to use the service.
The country is what matters
ChatGPT and Claude don't take numbers from every country. That's why we show a chance for each country — how the service has taken its numbers in recent days. Pick a high one: ChatGPT from $0.10, Claude from $0.17.
A number doesn't change where you are. If the service isn't available in your country, a number won't fix that — both publish their country lists in their help pages.
Step by step
- Open the ChatGPT or Claude page and pick a country with a high chance.
- Buy a number — it shows up on the order screen right away.
- At the phone check, choose the same country and enter the number without the country code.
- The code appears on the order screen and in our bot — enter it on the site.
If the number is rejected
If the service says the number isn't valid or has already been used, no code will come to it. Take a number from another country — the first one can be cancelled with a refund after 2 minutes. No code within 20 minutes — the money goes back to your balance by itself. The other reasons are in “The code isn't arriving: 7 reasons”.
