Has NACHA provided a definition or examples of the term "readily identifiable" in regards to ACH authorizations? From an audit standpoint, I think the form/notice would need to state (separately from the body/terms of the notice), that the notice is a ACH Authorization Form/Notice. However, I can't find how "readily identifiable" has been defined.

We are in the process of creating a notice and the Bank would like to just state within the body of the notice that the letter is to confirm the person's authorization to process the ACH transaction which was provided over the phone. I don't think this is enough....but I could be wrong. Any feedback would be appreciated. Thanks.
