The 'update your BVN' message: how to tell it's a scam

What the message looks like

A text or WhatsApp message "from your bank" asking you to click a link or call a number to update your BVN or NIN.

How to tell it's a scam

The message says your account will be blocked or restricted today unless you 'update' or 'link' your BVN, and gives a link, a number to call or a form. Then they ask for your BVN, card details, PIN or the OTP your bank sends.

Your bank will not ask you to update your BVN through a link in a text or WhatsApp message, and no real bank staff will ever ask for your PIN or OTP. Anyone with those can empty your account.

If you're worried about your account, go to your bank's own app or branch, or call the number on the back of your card.

The tell: Your bank will never ask for your BVN, card PIN, password or one-time code (OTP) by text, call or WhatsApp. Call your bank on the number on your card.

Already clicked, paid or shared details?

If you've sent money or shared your PIN or OTP, call your bank at once on the number on your card and ask them to block the account. Anyone who asks for a fee to recover your money is a second scam.

What to do with a message you're not sure about

  1. Don't click the link, reply, or call the number in the message.
  2. Check for yourself: open the company's own app, or type its website address yourself.
  3. If it claims to be family, call them on the number you already have.
  4. Report it (below), then delete it.

Warn your family or group chat

Scams work best on people who haven't seen them before.
