CIP applies when a "customer" opens an account. Escrow accounts are generally opened by the bank not the borrower; CIP doesn't apply in this circumstance. While the borrower's name, TIN, and address are necessary for information reporting purposes, the borrower has no access to the funds.
In any case, the loan should show up on the balance sheet the same day the escrow account does and if CIP has been performed on the loan...
As Brenda notes, the practice is going to generate a lot of false positives in terms of apparent violations.
