The proposed rule requires you to gather certain information about each customer/authorized signer (name, date of birth, addresses, TIN, etc.).
Then, your CIP should identify on a risk-associated basis, how (or if) you will verify this data for each "customer." If you decide that the risk is low, you may decide not to verify the data you receive from that class of customers, or may use some less costly verification method.
So you have an option - but be ready to justfy your choices to examiners and Treasury.
