Safaricom Call Barring (Blocking) Activation Codes

Call Barring is a feature that is used to block all calls or SMS of a certain type e.g. all incoming or outgoing calls. This service is provided by the network operator and therefore can be accessed by any subscriber regardless of their phone type.

Barring however cannot be used to block calls or SMS from specific numbers. For that you may need to install a call blocking app however some Android phones and Windows Phone do come with a call blocking (filter) feature.

Safaricom provides the options to bar the following call and SMS types:
  • Incoming or Outgoing Calls
  • Incoming or Outgoing Calls When Roaming
  • Incoming or Outgoing SMS
  • International Calls

To activate or deactivate any of these one uses specific codes that are dialled just like normal USSD codes. Let's take a look at them.
