Can I edit or update my company listing myself? 

You have the ability to input and update your company profile content independently at any time, and then immediately verify it within your company profile. You do not need to rely on specific service times or external support for profile processing.

To make edits to your company profile, simply log in to our website wlw.de, wlw.at, or wlw.ch using the "login" button with your username and password, and navigate to "my account." All your company profile content and products & services can be managed here.

If you do not yet have a login for your user account, you can easily activate your access.
