OpenAI Verification Use Cases
OpenAI SMS Verification FAQ
Can NexSMS numbers be used for ChatGPT and Codex?
Yes. ChatGPT, Codex and the OpenAI API all run on the same OpenAI account. Once you complete OpenAI account registration and login verification with our real carrier numbers, you can use ChatGPT, the Codex coding agent and the OpenAI API normally.
Is registering ChatGPT with a NexSMS OpenAI phone number reliable?
All our numbers are real carrier numbers that can receive OpenAI's SMS codes for sign-up and login verification. Success also depends on OpenAI's risk controls, so we do not promise a 100% rate.
Can one number receive OpenAI codes more than once?
Yes. Long-term premium numbers support repeated receiving within their validity, so the same number works for the initial registration, later logins, and password recovery.
Should I choose a short-term or long-term number?
Short-term standard numbers are affordable with about 30 minutes of validity, ideal for one-time verification. Long-term premium numbers stay valid for 12–90 days and are renewable, suited to users who keep an OpenAI account bound long term.
