Fraud Detection

Protecting you from unauthorized use of your debit card is one of our top priorities. Should you discover transactions that appear to be fraudulent on your account, please contact our support department immediately by calling 800-808-6402.


If fraud is suspected on a debit card transaction, you may receive a text notification from the Affinity Credit Union Fraud Department, dependent upon your security and contact settings. The text will inquire about the legitimacy of specific transaction(s) and provide an 800 number to contact if the transactions are fraudulent.


You can use your Affinity mobile app to manage your debit card notifications. In the mobile app, select "Manage My Cards" by pressing the "More" tab at the bottom right of the screen.

From here, you can:

  • configure your alert/notification settings
  • temporarily lock your card if you suspect fraud
  • report your card as lost or stolen.
