1

Open phone numbers

Go to account management in your account. There, click on Phone numbers.

2

Select extension

Then click on Extension.

4

Extend phone number

Here you can now extend the desired local phone number .

5

Confirm booking

Important notes:

  • An extension can only be booked for a German local phone number. International phone numbers or mobile phone numbers cannot be extended.

  • A phone number that has already been extended cannot be extended again. Phone numbers within an extension cannot be ported.

  • Ported local phone numbers cannot be extended during the porting process. The ported phone number can only be extended after the porting process has been successfully completed.
