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 0848 86 80 86 (CHF 0.08/min) or email customercare@local.ch.
