ChatGPT & OpenAI SMS Verification Numbers

OpenAI locks a phone number to one account for good — verify with it once, and it won't work for a second account, no exceptions on their end. If you need another account for development, testing, or because your usual one hit that wall, you need a different number to do it. Ours start at $0.05 and the code usually lands within a few seconds.

Why people do this instead of using their own number

One number, one account — that's the actual rule.OpenAI ties phone verification to a single account permanently. If your real number already verified an account once, it's done — it won't work for a second one. A rented number sidesteps that without touching your own line at all.

Building or testing something with the API. Developers spinning up a fresh account to test integrations, rate limits, or just a clean environment away from a personal account run into the exact same one-number wall — a separate number per account is the only way past it.

Worth being straight about this.A rented number gets a new account through the phone-verification screen, nothing more. What counts as acceptable use of multiple accounts is entirely OpenAI's own call under their terms of service — this doesn't change that or work around it.

How to verify OpenAI/ChatGPT in 5 steps

1
Register
Free, takes about 30 seconds. No ID, no personal phone number.
2
Add funds
Crypto only for now (BTC, USDT, and a few others) — $5 minimum. Annoying if you just want to test one $0.05 number, but that's where it sits right now.
3
Grab an OpenAI number
Search "OpenAI" in the services list, hit Get Number.
4
Enter it during signup or verification
Wherever ChatGPT or your OpenAI account is asking for a phone number, that's where it goes.
5
Wait a few seconds
The code lands in your dashboard on its own, no refreshing needed. Type it in and that number's done its job.

Questions people actually ask

Does a rented number actually work for ChatGPT/OpenAI verification?
Yes — OpenAI just needs to send an SMS to the number you give it. Ours receive that the same way any real line would.
Why would I even need a separate number for this?
Because OpenAI locks a phone number to one account permanently — once your real number has verified an account, it can't verify a second one. If you need another account, it has to be a different number, full stop.
Will OpenAI definitely accept the number, though?
That we can't promise. OpenAI runs its own risk checks on incoming numbers, and once in a while one gets rejected before anything's sent — that's their call, not ours. What we control is delivery: no code, no charge, cancel the activation and you're refunded.
How fast does the code arrive?
Usually within a few seconds. Occasionally slower if OpenAI's own systems are backed up, but that's rare.
Can I just add $1 to try one number?
Not right now — $5 is the floor, and it's crypto only, no card payments yet. Numbers themselves are still $0.05, so $5 covers plenty of tries.
My account got suspended or rate-limited — does a new number fix that?
No, and we won't pretend otherwise. A rented number only gets a new account through the phone-verification step. Whatever got the old account flagged is a decision OpenAI makes on its own, and this doesn't touch that.
Can I automate this instead of clicking through the dashboard?
There's an API if you're verifying more than a couple of accounts — same request/response shape SMS-Activate used to run, so old integration code mostly just works.
