{% endstep %}
{% endstepper %}

{% hint style="info" %}
**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.
