We check misspellings, look-alike characters, and the Nubank name combined with words like “login”, “secure”, “online” across common domain endings. A registered lookalike is not proof of a scam: companies often register typos of their own name to protect customers. But you should never trust a message from one.

Scams using the Nubank name
Bank impersonation is the most expensive scam for victims. The caller or message sounds urgent and official on purpose.
Move your money to a safe account
Someone claiming to be your bank's fraud team says your account is compromised and asks you to transfer money to a safe account. No genuine bank will ever ask you to do this.
Read me the code we just sent
The caller asks you to read back a one-time passcode sent to your phone. That code is what lets them into your account or approves a payment.
Unusual activity alert
A text about a suspicious payment asks you to reply or follow a link to stop it. Call the number on the back of your card instead.

Step by step
How to check a message that claims to be from Nubank
- 1
Look at the actual sender address, not just the name. Tap or hover over the name to reveal it. It must end in @nubank.com.br, or a subdomain of one.
- 2
Do not use links or phone numbers from the message. Type nubank.com.br into your browser or open the official Nubank app, and check your account there.
- 3
Slow down when you see urgency, small fees, gift cards, crypto, or requests for codes and passwords. Those are the levers every scam pulls.
