To register several companies, log in to your Extranet account and from the home page, click on "Create a company" at the bottom of the page to add a new company to your account.

See our tutorial for all the steps involved in registering a company:

To declare multiple companies from a single account, they simply need to be linked to the same declarant profile.  

Each brand/company has its own file on the Extranet, attached to the Declarant's profile. If the same declarant profile is entered for several companies, he will be able to access all the companies by logging on to his Extra,et space. 

You must then go to each company file to make the associated declaration.
