Temporary number for Nubank verification
Nubank, Brazil's largest digital bank, asks for a mobile number during account opening and confirms it with a 6-digit SMS code. The number is tied to the account: Nubank sends login codes to it on new devices and uses it for security alerts. Nubank is strict with VoIP ranges and accepts real carrier lines, so choose a physical-SIM country. Opening the account also requires a CPF and an identity document. Brazil is available in the SMS Nitro dashboard with the price shown before you confirm.
Can I verify Nubank with a temporary number?
Yes. Pick Nubank in the catalog, choose a country (Brazil have the best recent results), enter the number in the app and read the 6-digit code in your dashboard. The number is reserved for 20 minutes and you are charged only when the SMS arrives. Nubank rejects most VoIP numbers, so choose a country marked physical SIM. Numbers for Nubank are unlimited and never run out.

Why use a temporary number for Nubank?
- Open a Nubank account with your CPF after moving to Brazil, before your local SIM is active.

Best countries for Nubank verification
Nubank serves Brazil, Mexico and Colombia with separate apps, and each expects a local mobile number. For the Brazilian app choose Brazil (+55), available in the SMS Nitro dashboard; the price is displayed before you confirm. Nubank runs a carrier check and rejects most VoIP ranges, so pick the physical-SIM pool. For Nu México or Nu Colombia pick Mexico (+52) or Colombia (+57) in the dashboard, again with the price shown before confirming. Nubank also asks for a CPF, CURP or cédula, so the number alone does not open an account.
Tips to keep the Nubank account
- Confirm your email and set the app PIN in the first session; Nubank then has two channels besides SMS to verify you.
- Keep the app installed on the phone you used for the first login; Nubank binds the account to that device.
- Type the number as a two-digit area code plus nine digits; the app applies +55.
- Once you hold a long-term Brazilian line, change the phone in the app's profile settings so future device-change codes reach you.
If Nubank rejects the number or the code is slow
- The code is rejected as wrong → read the newest SMS in your dashboard; Nubank invalidates older codes each time you tap resend.
- No SMS in two minutes → tap resend once. If nothing arrives before the 20-minute reservation ends, the hold is refunded to your balance automatically.
- Nubank says the number is already registered → each number can be linked to one Nubank account. Request another number and repeat.
Frequently asked questions
Does Nubank accept a temporary number for the SMS code?
Yes, when the number is a Brazilian mobile line from a real carrier. Nubank rejects most VoIP ranges, so choose Brazil with the physical-SIM label in the SMS Nitro dashboard. The 6-digit code appears in your dashboard, and you pay only if it arrives.
How much does a Brazilian number for Nubank cost?
The current price is shown in the dashboard before you confirm the request. The number is reserved for 20 minutes, you pay only if the code arrives, and the held amount is refunded automatically when no SMS comes in.
Can I open a Nubank account without a CPF?
No. Nubank Brazil requires a CPF and an identity document in addition to a phone number. Expats usually obtain the CPF first and then open the account. The phone number is only used to receive confirmation and login codes.
Will Nubank send codes to the number later?
Yes. Nubank sends an SMS when you log in on a new device, reinstall the app or change security settings. Confirm your email and set the app PIN during signup, and update the phone in the app once you have a long-term Brazilian line.
Why does Nubank reject some phone numbers?
Nubank checks the carrier behind the number and declines most VoIP and internet-based ranges, as well as numbers already linked to another account. Numbers from the physical-SIM pool come from real Brazilian carriers, which is what the check looks for.
How much does a temporary number for Nubank cost?
From $0.11 per delivered code in India at the last price snapshot; physical-SIM pools and strict countries cost more. The exact price for Nubank is shown before you confirm and is frozen until the SMS arrives.
How long is the number reserved for Nubank?
20 minutes. During that time the number is yours alone and every SMS from Nubank appears in your dashboard. You pay only when the first code arrives.
What if the Nubank code never arrives?
You are not charged. The held amount returns to your balance automatically and you can take another number for Nubank, from the same or a different country, right away.
Does Nubank accept virtual numbers?
Rarely. Nubank checks the carrier behind the number and refuses most VoIP ranges, so pick a country marked physical SIM; those are real carrier lines.
Can I receive a second Nubank code on the same number?
Yes, while the number is active, at no extra cost. Ask Nubank to resend and read the new SMS in the same dashboard row; the latest code is the valid one.
Does Nubank see my real phone number?
No. Nubank only sees the temporary number you typed. Your personal number is never shared, and the SMS is read in your SMS Nitro dashboard, not on your phone.
