Important note

Fraudsters are currently stepping up their efforts to obtain sensitive banking data through fake emails. For example, bank customers are directed via a link in the email to an authentic-looking website that sends the data entered directly to the fraudsters or asks them to send sensitive data by email to a fake email address.

Please note: We will never ask you to disclose sensitive data by email. 

General security information on handling emails can be found, for example, on the website of the Federal Office for Information Security

If you are unsure or have already disclosed sensitive data, please contact your advisor at the bank or contact us at one of the following telephone numbers or email addresses:
