How can I block unwanted calls?

Unwanted calls can be blocked by your telephone provider – local.ch cannot block these calls. However, we can show you what you can do.
Unfortunately, individual phone numbers cannot be blocked – only anonymous incoming calls.
If these calls are made anonymously, you can activate service 99.

 Service 99 activation:

  •  Pick up the receiver and wait until you hear the dial tone.
  •  Press the asterisk (*) key, enter 99 and then press the hash (#) key.
  •  Wait for confirmation and hang up.


 Service 99 deactivation:

  •  Pick up the receiver and wait until you hear the dial tone.
  •  Press the hash (#) key, enter 99 and then press the hash (#) key again.
  •  Wait for confirmation and hang up.


We can give you a new telephone number free of charge in the event of annoyance calls (advertising calls are not considered an annoyance).
For more information, please call 0800 86 80 86 or email customercare@local.ch.
