I think this is deposit banking 101 questions but still need help on this. I cannot find any regulation on the bank's internal deposit policy or procedures.

Currently, our bank's deposit policy and procedures are combined in one and there is no defined line between policy and procedures. I have got an inquiry from a potential customer if he can open a specific account. In no where, I cannot find any section for qualifications or account features. We have a TISA disclosure that is provided to a customer.

Is it okay that the bank's deposit policy or procedures do not include that part? What does other bank's deposit policy or procedure look like?

Whatever it does or doesn't include is fine; I've never seen or heard a reference to a deposit policy and cannot imagine what it might include. My point is, that it's not a regulatory requirement or even a suggestion, but that does not mean it's not a helpful document within your organization.
