Security Center

Protecting you and what you’ve worked hard to earn is our top priority. We rely on the latest security measures and a team of experts to monitor for suspicious activity, protect you from fraudulent purchases, and make sure you always have access to the banking experience you deserve. As our society becomes more connected and more reliant on technology, you also play an important role by not falling prey to fraudsters. You are our partner in preventing cybercrime.

How to Report Fraud and/or Identity Theft

  • If you think your identity has been stolen, contact us at (605) 874-2191 immediately.
  • Contact the fraud department of any one of the three consumer reporting companies - Equifax, Experian, or Transunion – to place a fraud alert on your credit report.
  • The Consumer Financial Protection Bureau has additional information.

Protect Your Online Information

  • Use strong online passwords. Don’t share your passwords with others or use obvious passwords such as your birthday or the last four digits of your social security number.
  • Click with caution. Never click on links sent in unsolicited emails. Never open or download from unverified sources. Keep your computer updated and install and maintain anti-virus software.

Protect Your Information

  • Don’t carry your Social Security card in your wallet or write your number on a check. Give it out only if absolutely necessary.
  • Don’t give out personal information on the phone, through the mail or over the internet unless you know you are speaking to a trusted source.
  • Keep your personal information in a secure place at home.
  • Don’t fall prey to scams! People who talk about scams and have a general awareness of them, are less likely to fall prey to them. Review our Common Scams Brochure.


Our staff at DNB will never ask for your personal information on the phone or by email unless you are the initiator. If you have doubts or are uneasy about a situation that may have occurred, contact us immediately!
