668 SIM Information System
 
Keeping your security as a priority, Pakistan Telecom Authority has introduced a system whereby you can find the number of SIMs of each mobile operator registered under your name. Just follow the simple steps below:
  
SMS your CNIC number (13 digits, with no spaces of dashes) to 668 from your mobile.
PTA will immediately send you an SMS telling you the number of active SIMs of any operator issued in your name
On receiving the SMS, if there are any unexpected SIMs in your name, contact the nearest Customer Service Center of the relevant mobile operator with your original CNIC and mobile phone. You can fill out PTA’s prescribed form and get all unwanted numbers removed from your name within 48 hours of the receipt of the complaint.

  
Since this service is exclusively available over SMS to 668, Customer Services will not be able to share the list of numbers registered against your CNIC with customers. After you file your complaint, your 668 status/SIM information will be updated within 45 days of receipt of the complaint.
