A genuine phone number for ChatGPT and OpenAI verification
Short answer: You can use an SMS Conecta number to receive ChatGPT and OpenAI verification codes by SMS. It is a genuine mobile, local or toll-free number that works for signing up with most apps. If OpenAI does not accept it, the 7-day replacement guarantee gives you a free new number, up to 2 times.
OpenAI asks for a phone number in a couple of places: some new ChatGPT sign-ups, and the verification tied to generating an API key on the developer platform. Because OpenAI caps how many accounts a single number can verify, it pays to pick a number you plan on keeping.
Where OpenAI asks for a phone number
Most people run into phone verification in one of two spots. The first is ChatGPT itself: OpenAI's help center describes phone-only sign-ups, a beta letting new users in certain countries create an account with nothing but a phone number. The second is the OpenAI developer platform, where phone verification is tied to generating an account's very first API key.
In both cases the purpose is identical: the number proves a real person is behind the account and makes free-usage abuse harder to pull off. That is also why OpenAI limits how often a single number can be reused, making a shared or recycled number a poor fit.
What OpenAI's help center says about verification
Since the codes travel by SMS, a mobile number is the obvious pick. Every SMS Conecta number includes unlimited incoming SMS, and each message shows up in your dashboard the instant it arrives.
| Topic | What OpenAI documents (as of September 2026) |
|---|---|
| How codes are sent | For phone-only sign-ups, by SMS or, where available, WhatsApp; not by email or phone call |
| Reuse for API verification | One number can complete phone verification up to 3 times, across different accounts |
| Reuse after deleting an account | The number is removed from OpenAI's system 30 days after a consumer account is permanently deleted, unless the account was disabled for a policy violation |
| Paid plans on phone-only accounts | Upgrading to a paid plan such as ChatGPT Plus requires adding and verifying an email address |
Why a dedicated number suits ChatGPT
Since one number can only verify a limited number of accounts, a number you keep for years is worth more here than one you swap out often.
- Your personal SIM stays apart from a work or developer account that colleagues may also be managing.
- A company can hold the number tied to its OpenAI organization instead of leaning on one employee's phone.
- Freelancers and agencies keep client projects on a number they control and keep renewing.
- People living abroad hold on to a stable number from home even as their local SIM changes.
Verifying ChatGPT or the OpenAI platform, step by step
- Create an SMS Conecta account with your email address and pick a country and a mobile number.
- Pay from your wallet with USDT or USDC; most numbers go active within minutes.
- In ChatGPT or on the OpenAI platform, open the phone verification screen and select the matching country code.
- Enter the number in full international format and request the code.
- Open the SMS inbox in your SMS Conecta dashboard, copy the code and paste it into OpenAI.
- Add a recovery email and, where offered, multi-factor authentication, so you are not relying on a single sign-in method.
If the code never shows up or the number is refused
First confirm the country code is right and that you have not fired off several codes in a row, which can trip rate limits. Wait a few minutes before trying again, and keep the dashboard open so you catch the SMS the second it lands.
If OpenAI says the number cannot be used, or it has already hit its account limit, the 7-day replacement guarantee covers you: one click gets a free new number in the same country, up to 2 times. If the number has not handled a single call or SMS, you can instead request a refund within 7 days.
Staying inside OpenAI's rules
Use the number for your own account or your organization's account, and stick to OpenAI's terms and usage policies. The per-number limits exist to stop people from multiplying free accounts, and an SMS Conecta number is not a workaround for that. If an account gets disabled for a violation, OpenAI keeps the number blocked, so there is no upside in trying.
What the SMS Conecta plan includes
Every number starts from $1.80 per month, billed yearly ($21.60 per year), whatever the country or type. It includes unlimited incoming SMS and calls, 500 outgoing SMS and 1,000 outgoing minutes a month, SIP credentials, call forwarding and a browser web dialer. You pay in USDT or USDC, and the number renews automatically from your wallet.

ChatGPT numbers — FAQ
Can I use an SMS Conecta number for ChatGPT sign-up?
Yes. The number receives SMS like a SIM and works for signing up with most apps. If OpenAI does not accept it, you get a free replacement within 7 days, up to 2 times.
Does OpenAI send the code by phone call?
For phone-only sign-ups, OpenAI's help center says codes go by SMS or, where available, WhatsApp, never by call or email. A mobile number with SMS is therefore the right pick.
How many OpenAI accounts can one number verify?
OpenAI documents a cap of 3 phone verifications per number for API key generation. Plan your accounts around that limit rather than trying to dodge it.

According to OpenAI, the number is cleared from its system 30 days after a consumer account is permanently deleted, unless the account was disabled for a policy violation.
