OpenAI maintains a blocklist of VoIP and data-center numbers. A US number from the verified pool is on the allow side and works for ChatGPT sign-up and 2FA.

- Open an account and top up from $5 (crypto or card).

The way OpenAI verification usually fails
Most common failure: OpenAI’s blocklist rejects VoIP and data-center numbers, so the sign-up stalls.
FAQ
Do VoIP numbers work with OpenAI?
No. OpenAI blocks VoIP and data-center ranges. Use the physical pool instead.
What if the code does not arrive?
The charge refunds itself automatically at the 20-minute mark if no SMS arrives. No ticket or chat is needed.
Can I receive multiple codes on the number?
Yes. The 30-day rental accepts unlimited SMS, including later 2FA prompts.
Can I renew the number?
Yes. You can renew the same number for re-login and continued use after the rental ends.
