Fraud alert calls

We want to make sure that using your debit card is as safe and convenient as possible. That’s why we utilize a fraud monitoring program to alert you when there is suspicious activity detected. If you receive one of these alert phone calls from the fraud detection center, simply follow the prompts to verify activity. You will have the option to speak to a live associate during the call.
