Are you a victim of fraud?

  • Have you clicked on a link or opened an attachment in a fraudulent email?
  • Have you shared sensitive information following an unsolicited phone call?
  • Have you noticed any unusual money movements in your bank account?

Email and texting: Be vigilant

Fraudsters are increasingly able to imitate emails and text messages sent by National Bank. However, you should know that National Bank never asks for your personal information, your login credentials or your banking information by email or text message. In addition, the Bank never inserts a link to your online bank's sign in page in an email or text message. If you receive a message that appears to come from the National Bank asking you for this type of information, do not click on any link because it is probably a fraud attempt.
