Due to the high volume of email that Guaranty Bank receives daily, it is necessary to filter messages for content and source information to keep our network and information as secure as possible. Because of this, some emails coming in may be delayed or blocked. 

If you have an urgent request or one that involves confidential details like your account number or social security number, do not e-mail this information. Please call Guaranty Bank directly at (319) 286-6200.
