RaboDirect's regulatory status (our primary regulator is the Dutch Central Bank) has nothing to do with the requirement to request a customer's PPSN. Banks are obliged by the Revenue to request a customer to provide original proof of PPSN when opening a savings account. To our knowledge Anglo Irish Bank, Northern Rock, Halifax etc require proof of PPSN when opening savings accounts.
It might provide some comfort to customers to know that the Data Protection Commissioner is very sensitive about the storage of a customer's PPSN and has specific regulations that must be followed in this regard.
The Financial Regulator has guidelines that all banks must follow with regard to Anti-Money Laundering. As RaboDirect we are stringent but fair in our application of these guidelines.
I trust this helps clarify the matter.

RaboDirect
