TellMe whistleblower portal

Information concerning violations of legal obligations or Deutsche Telekom rules and regulations can be reported to Group Compliance Management through the Tell me! whistleblower portal.

Compliance with laws and internal policies and principles of conduct is of major importance to Deutsche Telekom because we strongly feel that the key to the company's success is based on integrity, ethics and personal responsibility. We therefore strive to avoid any risk that could compromise our integrity and damage others. If we are to live up to this responsibility, it is of utmost importance that we are made aware of any compliance related misconduct.

Deutsche Telekom therefore provides all employees and external parties with the appropriate means to report potential violations of laws and internal regulations through the TellMe whistleblower portal, which has been in place since 2006. This also includes tipp-offs to human rights or environmental risks and violations of rights along our global supply chain. This can affect the actions of our employees in the Group companies' own business area or those of our suppliers or business partners.

If requested, your data and information are subject to confidentiality to the extent in line with the relevant legal stipulations. All tip-offs will be assessed thoroughly, cases of suspicion will be investigated and sanctions consistently applied if applicable.

Please, help us to continue to be a reliable business partner and a successful service provider to our customers by blowing the whistle on serious violations of the law or infringements of rules and regulations concerning Deutsche Telekom.
