Obstacles to using e-services

There are reasons why e-services may be unavailable. One is that the status of a service has been set as "passive" for a user within My e-Services. This may, for example, be because the user's vehicle is recorded as having an alteration prohibition in the register.

Data protection

Data in the portal is transferred over a secured connection (SSL). A security audit has been performed on the portal.

General terms of use

Users must approve the Terms and Conditions of Service before they can view their data and make use of the My e-Services portal. The approval is given when logging in. The terms can be viewed in advance here.
