Your privacy at the counter and on the telephone

If you have any questions, you can call us, or you can stop by our counter (by appointment). We first ask for your citizen service number (BSN) and date of birth. We do this to better protect your personal data. Only then do we share confidential information. By doing so, we want to prevent the information from reaching people who are not entitled to it.

Some personal information we never give out over the telephone. This includes your citizen service number (BSN), date of birth, and address details.
