When an account goes to zero (Assuming this is the ONLY account customer has), it goes to a "CLOSED" status" after 30 days, but the account number is actually still on our computer system for two years. If a customer still had a deposit slip a year later, and came in, made a deposit using that deposit slip (maybe put through ATM), no one would know until the next morning when the deposit rejected. Operations would change the status to "active" and make the deposit. In this case are we still obligated to re-CIP this customer? The account is effectively opened, but we would have to re-cip after the fact. If the customer was originally CIP when the relationship was established, would it still suffice if the customer made a deposit to a closed deposit account.
