Safaricom: How to Check Phone Numbers Registered with Your ID

Safaricom PLC has introduced a Short Message Service (SMS) allowing subscribers to check whether they are registered to more than one phone number.

This has been enabled through the *106# USSD code. This is different from the 707 service, which alerts the Safaricom customer when someone tries registering a new SIM card with their ID number.

How to use the *106# Service

• Dial *106# on your Safaricom mobile phone
• From the list, select “Check registered numbers”
• Safaricom will display and send you an SMS with phone numbers registered using your identification.

How to Deregister a number

• The next prompt will allow you to report the unrecognized number.
• Safaricom will send you a confirmation that the number will be investigated within six hours.
• In case you recognize the number or have requested for cancellation by mistake, you can still reverse the investigation request within the six-hour period.
