Important Information About Your Online Banking Access

As you may know, Guaranty Bank became a division of First Citizens Bank some time ago. As we prepare to transition Guaranty Bank customers to First Citizens Bank systems, we want to provide you with the below information.

Guaranty Bank customers who have already enrolled in Guaranty Bank Online or Mobile Banking prior to June 2, 2018:

During the weekend of August 10-12, 2018, your Guaranty Bank accounts and Online and Mobile Banking access will automatically transition to First Citizens Bank. Prior to this, you’ll receive by mail a packet of information about the conversion of your accounts and services to First Citizens Bank and a separate mailing with important log-on information for your Online/Mobile Banking access.
