A Brazilian mobile number for ChatGPT and OpenAI verification

Why a +55 line for your ChatGPT account

In Brazil almost every account ends up tied to a mobile, and people who work with Brazilian clients, agencies or teams often want their tools on a Brazilian number too. A dedicated line also means a change of carrier or a lost chip doesn't leave your OpenAI account attached to a number you no longer control.

For Brazilians living abroad, a number that works through a web dashboard keeps the account reachable without roaming or a second handset.

When OpenAI asks a Brazilian user for a number

OpenAI says phone verification isn't generally required to create an account or use ChatGPT. Phone-only sign-up rolled out mostly in other countries, so a Brazilian account starts with an email or a Google, Apple or Microsoft login, and the number is requested at these points.

• Codex in the ChatGPT desktop app, which can require phone verification even if you use an authenticator app.
• The first developer key you create on platform.openai.com.
• Text-message MFA, if you choose it, with a 6-digit code on each protected sign-in.

Pick your Brazil number

These Brazil numbers are listed right now (31 in total). Choose one on the country page; the hidden digits are assigned when your order is approved and the number is activated.

Brazil

Eleven digits: DDD plus the ninth digit

A Brazilian mobile has eleven digits after +55: a two-digit area code (DDD) and a nine-digit number that starts with 9. Anatel added that leading 9 to all mobiles between 2012 and 2016, so older contact lists and some foreign-built forms still expect eight digits. Keep the 9; without it the number doesn't exist.

Brazilians also write long-distance numbers with a 0 and a two-digit carrier code in front, like 0 21 11 9…. Strip all of that. On OpenAI's screen, change the country from its United States default to Brazil and type the DDD and nine digits, with no 0 and no carrier code.

How the code reaches a Brazilian number

Even though WhatsApp is how much of Brazil communicates, OpenAI's WhatsApp verification covers a different set of countries, so a +55 number gets its code by SMS. OpenAI doesn't send codes by email or voice call. With SMSCreation, the text appears in your web dashboard's inbox.

The developer-key check happens once per account. Codex and text-message MFA may ask again, and each time the code goes to the same Brazilian number, because OpenAI doesn't allow switching to another.

Step by step with a Brazilian number

1. 01Order a Brazilian number and read its DDD and nine-digit number in your dashboard.
2. 02Reach OpenAI's phone step in the desktop app or on platform.openai.com.
3. 03Select Brazil and type all eleven digits, keeping the 9.
4. 04Request the code and copy it from your SMS inbox.
5. 05Turn on MFA under Settings → Security and login.
6. 06Leave auto-renew on so the number remains yours.

Limits worth knowing

• The number is permanent on the OpenAI account; there's no option to change or update it.
• Three verifications per number in total, and after its first one it can't create a new account.
• “Too many signups with this number” means OpenAI has seen the number before, possibly with a previous holder; OpenAI says there's no workaround.
• Landlines, VoIP, Google Voice and premium numbers are refused.
• “Unsupported country” concerns your access location, not the +55 number.

Why it works with WhatsApp, Facebook, Telegram & Google

Apps check more than the digits: they look up the line type, the country format and whether the number can actually receive their code. Every SMSCreation number is a real mobile number in its country's official format — not a VoIP line — so it passes those checks the same way a SIM in your pocket does.

And we stand behind it with a 7-day replacement guarantee: if your number doesn't work with WhatsApp, Facebook, Telegram, Google or any app you need, we replace it free with a new number in the same country — or refund 100% if you prefer.

• Non-VoIP, real mobile line type — line-type checks see an ordinary SIM number, not a VoIP line
• Official country format with the right country code, prefix and digit count
• Unlimited incoming SMS and calls — codes arrive by text or through the “call me” option
• Private to you — never listed on public SMS sites, so it isn't flagged or rate-limited
• Yours for as long as you want — re-verification and account recovery keep working

Price, renewal and the 7-day guarantee

A Brazilian number costs from $1.80 a month on the yearly plan ($21.60 billed yearly), with unlimited incoming SMS and calls, 500 outgoing SMS and 1,000 outgoing minutes a month. It stays yours for as long as it renews.

If the number doesn't work for OpenAI's verification, the 7-day replacement guarantee gives you a free replacement Brazilian number within 7 days of activation, or a 100% refund. Unused numbers, with no call or SMS, can be refunded within 7 days, no questions asked.
