You may not know it, but you have around-the-clock protection against the increasingly savvy perpetrators of card fraud. That's because your United Bank Card is protected by a fraud monitoring system. If fraud is suspected, an analyst will call you and will identify themselves as "The Security Department" on behalf of United Bank. If you cannot be reached, a message will be left asking you to call 1-800-830-1925 to speak to an analyst. This is the only phone number that is valid.
