Telephone number portability

Telephone number portability refers to the ability to keep your telephone number when change telephone service providers. In Germany, for instance, telephone number portability is regulated by law. The key provisions are defined in paragraph 46 of the Telecommunications Act (TKG). Telephone customers are thereby legally entitled to keep their telephone number when switching providers. Telephone number portability technically involves disconnecting the number from the old connection and registering it to the connection with the new provider. Telephone number porting is typically subject to a charge.
