Is there a regulatory requirement that a bank send a customer with a CD an advice of credit for interest earned and credited to the principal of the CD? Currently, if a customer only has a CD with the FI, they do not receive any such notification. If a customer has both a checking account and a CD, the interest earned is actually disclosed on the customer joint statement. So, is it alright for the bank to disclose interest earned in this manner?

There are no regulatory requirement to provide a separate interest earned notice.
