How To


Telecommunication Authority (PTA) has launched a new automated Lost & Stolen Device System (LSDS) for blocking lost, stolen, and snatched mobile phones. The new System will provide ease and facilitation to the users who want to get mobile phone blocked in case it has been stolen, snatched or lost. Complainants can easily file a request with PTA to block the IMEI of such handset to prevent potential misuse.

LSDS is an automated system integrated with PTA’s Device Identification, Registration, and Blocking System (DIRBS). The stolen mobile phone will be blocked within 24 hours of reporting after necessary verification.


PTA’s online Complaint Management System

Users will have to lodge a blocking request with PTA through PTA’s online Complaint Management System (CMS) available at For more information/queries, users may contact PTA Consumer Support Center (CSC) toll-free number 0800-55055 (9:00 AM to 9:00 PM 7 days a week).

The complainant will receive a complaint reference number upon successful registration of the blocking request.

If the phone has been recovered, the complainant will have to follow the same procedure for unblocking through CMS and mention their complaint reference number and other mandatory detail given to them earlier for blocking of mobile phone. 

The user will receive an SMS on the registered number once the mobile phone is unlocked.

It may be mentioned that currently stolen, snatched, and lost mobile phones can be blocked or unblocked by calling PTA’s toll-free number 0800-25625, sending an email to [email protected], or through CPLC, Karachi.

After the new System’s launch, these mediums will not be available for blocking or unblocking phones.
