OpenAI asks for phone verification alongside your email when you create a ChatGPT account. Two practical problems follow: one number can only verify a limited number of accounts, and OpenAI rejects certain number ranges outright. A single-use virtual number completes the check and then returns to the pool.
Why does OpenAI reject some numbers?
OpenAI's verification layer looks at three things:
- Line type. VoIP and internet-based numbers are rejected at a high rate. You need a real carrier line (non-VoIP).
- Number history. A number already used many times for OpenAI verification may not be accepted again.
- IP and country match. If the country you connect from differs wildly from the number's country, extra checks trigger.
These are weighed together. Choosing the right line type and a country that matches your IP noticeably improves the success rate.
Step by step
- On buy a number, select OpenAI / ChatGPT as the service.
- Pick a country that matches the IP you are connecting from.
- Paste the number into OpenAI's phone field.
- The incoming code appears live in your dashboard.
- Enter the code; the account is verified and the number is released.
Which country performs best?
| Country | Price | OpenAI fit | When to choose it |
|---|---|---|---|
| Turkey | Low | High | First choice on a Turkish IP |
| Germany | High | High | Most consistent on a European IP |
| Netherlands | High | High | Good alternative when Germany is out of stock |
| Russia | Lowest | Medium | Cheap, but success rate varies |
| United States | High | Medium-High | Sensible on a US IP |
OpenAI verification is pickier than most services. If the first attempt fails, try a different country — a cancelled order is refunded to your balance, so retrying costs you nothing extra.
How many attempts does it take?
With the right country and a non-VoIP line, most verifications succeed on the first try. If you get rejected, work through this order:
- Take a second number from the same country (different number history).
- Match the number's country to your IP country.
- Clear browser cookies and try again in a fresh session.
Every failed attempt is refunded automatically, so retrying is free. The rules are on the refund policy page.
Frequently asked questions
Can I use it to pay for ChatGPT Plus? No. A virtual number is for phone verification only; subscription payments need your own card.
What if the account asks for phone verification later? You will no longer have that number, so you would need a new one. Adding a recovery email to the account reduces this risk.
Why don't VoIP numbers work? OpenAI treats VoIP ranges as easy to automate and filters them. We explained the technical difference in what is a non-VoIP virtual number.
Will my account be banned? A virtual number alone is not a ban reason; how you use the account matters. See will a virtual number account get banned.
