Sim Database Find Free Sim owner
A complete guide to understanding Pakistan's SIM Card Database — how it works, what data it holds, and why it matters for every mobile user in Pakistan.
The SIM Database is Pakistan's official national registry of all mobile SIM cards linked to citizens' CNIC (Computerized National Identity Card) numbers. Maintained and regulated by the Pakistan Telecommunication Authority (PTA) and NADRA, it serves as the backbone of mobile identity verification across the country.
The Official Definition
A SIM Database (Subscriber Identity Module Database) is a centralized digital registry that stores and manages information about every SIM card issued by telecom operators in Pakistan. It links each SIM card to the registered owner's biometric and identity data, ensuring that no SIM can be activated anonymously.
In Pakistan, all four major telecom operators — Jazz, Telenor, Zong, and Ufone — are required by law to feed their subscriber data into this centralized PTA-managed system, making it the single most comprehensive telecom identity database in the country.
How Does the SIM Database Work?
The SIM Database operates through a structured 4-step verification and registration process that every new SIM card must go through before it can be activated.
Biometric Verification
Customer visits a franchise and provides their CNIC. Fingerprint is scanned and verified against NADRA's biometric database in real time.
CNIC Linking
The new SIM's MSISDN (mobile number) is linked to the customer's CNIC number in the operator's system and forwarded to PTA.
PTA Central Registry
PTA's central SIM Database receives and stores the record, cross-checking if the 5-SIM limit has been reached for that CNIC.
SIM Activation
If all checks pass, the SIM is approved and activated. The record becomes permanently searchable in the national SIM database.
What Information Is Stored in the SIM Database?
The SIM Database is a rich repository of subscriber information. Here is a breakdown of the key data fields maintained in the system:
| Data Field | Description | Type |
|---|---|---|
| CNIC Number | 13-digit national identity number of the SIM owner | Identity |
| Full Name | Registered name as per NADRA records | Identity |
| Mobile Number | The 11-digit mobile phone number (MSISDN) | Telecom |
| Network Operator | Jazz, Telenor, Zong, Ufone, or SCOM | Telecom |
| Activation Date | Date and time the SIM was officially activated | Temporal |
| SIM Status | Active, Blocked, or Deactivated | Status |
| Biometric Record | Fingerprint verification timestamp from NADRA | Biometric |
| Region / City | Location where the SIM was registered | Location |
