Within certain webspace tariffs you have the option to register additional domains as co-domains. An overview of the maximum numbers of co-domains can be found on our homepage.

Order the future domain with a webspace tariff that supports co-domains.

Now you can integrate the additional domain into your contract via the customer center.
In order to do that please proceed as follows:

1. Log in to the customer center with your eMail address and your password.
2. Select the appropriate contract.
3. Choose the option "Domains" from the left menu column 

Here you find the maximum number of domains you can register as well as the already registered ones. Here you can register further domains for your contract.
