Receive SMS Online for OpenAI and ChatGPT Verification
OpenAI asks for SMS verification on many signups, and it is strict about reuse: digits that have verified accounts before get turned away. That policy killed public shared numbers for ChatGPT long ago. A private virtual number gives your signup fresh digits: pick a country below and read the code in your dashboard.
"This phone number is already in use": the OpenAI reuse limit
OpenAI caps how many accounts a single phone number can verify, and public receive-SMS numbers blew past that cap years ago. If you have seen "this phone number is already in use" or "cannot be used for verification", you have met the policy.
Because each activation here hands the number to one customer at a time, your signup is not competing with a thousand strangers for the same digits. That is the difference that matters for OpenAI specifically. No acceptance guarantee exists for any provider, OpenAI adjusts its rules continuously, but fresh private digits remove the reuse problem, and an activation with no received SMS can be cancelled with the hold returned to your balance.
How to receive a OpenAI verification code
Pick OpenAI and a country
Sign up, add balance, and choose OpenAI plus a country from the live table. A dedicated number appears in your dashboard immediately.
Enter the number at the OpenAI prompt
Use the number in the phone verification step for ChatGPT or the OpenAI platform and request the SMS.
Read the code and finish signup
The code lands in your dashboard. Enter it at the prompt and the account is verified.

One account per project, cleanly
Developers commonly keep separate OpenAI accounts for separate contexts: a personal account, a company one, a client project with its own billing. Each needs its own verification, and using a dedicated number per identity keeps them independent while your personal number stays private.
Will you need a code again next month?
A one-time activation covers one verification code. If the account may ask you to re-verify later, rent a virtual number instead: a rented number stays yours for days and receives every follow-up SMS on the same digits.
Automating signups for QA or provisioning accounts from code? The SMS verification API exposes the same ordering and polling flow programmatically, and the all services page lists everything you can verify.
Frequently asked questions
Can I use ChatGPT without giving my own phone number?
Where OpenAI asks for SMS verification, some number has to receive the code, but it does not have to be yours. A private virtual number receives it and shows the code in your dashboard.
Why does OpenAI say my number is already in use?
OpenAI limits how many accounts one number can verify. Shared public numbers and heavily reused SIMs hit that limit; a fresh private number does not carry that history.
Does this work for OpenAI platform and API accounts?
Yes. Platform signups that request SMS verification follow the same flow: enter the number, receive the code, type it in.
How many OpenAI accounts can one activation verify?
One. An activation is one number and one code for one signup. Order a separate activation for each identity you legitimately need.
What if the code never arrives?
Cancel the activation and the amount returns to your balance. Cancellation unlocks a couple of minutes after purchase.
