Thank you everyone for your input. It seems the distinction here is if the bank actually attempts to verify funds, is unsuccessful, and documents their attempt, is it acceptable to use the "Unable to Verify Funds" reason. Simply using this reason every time a customer deposits a credit card check without attempting to verify is not acceptable.
Another "Reasonable Cause" question: is checking a box on a hold notice that says "Confidential information indicates that the check may not clear" rather than specifically stating that the "Paying bank indicates that check not clear" acceptable? After reading the Commentary, it seems that you should only use the "Confidential" notice if there truly is a confidential reason such as check kiting or payee is insolvent or on the verge of insolvency.
