What Is SIM Information with System Number?
The system number in SIM verification refers to a unique identifier assigned to each mobile connection within Pakistan’s telecommunication database. This number serves as a digital fingerprint for your SIM card, linking it to your CNIC and personal registration details.
Many people confuse the system number with the mobile number or SIM number. Your mobile number is what others dial to reach you, while the SIM number (ICCID) is printed on the physical SIM card. The system number, however, is an internal reference code used by the Pakistan Telecommunication Authority (PTA) and network operators to track and manage SIM registrations.
Why Checking SIM Information Is Important
SIM verification has become a critical security measure in Pakistan’s digital landscape. With the rise of mobile-based financial services and digital authentication, ensuring your SIM ownership details are accurate protects you from potential fraud and identity theft.
The Pakistan Telecommunication Authority mandates proper SIM registration to combat criminal activities conducted through unregistered or fraudulently obtained mobile connections. By regularly checking your SIM information, you maintain control over your digital identity and can quickly identify any suspicious registrations.
Verification serves as proof of ownership when transferring numbers, recovering blocked SIMs, or resolving disputes with your network provider. Additionally, government regulations require all active SIMs to be properly registered with valid CNIC details. Failing to verify and maintain accurate registration can result in service suspension or permanent disconnection.
How to Check SIM Information with System Number
Method 1 – Online SIM Information System (PTA Portal)
The PTA official website offers the most comprehensive method for checking SIM details. Visit the Device Verification System portal and navigate to the SIM information section. You’ll need to enter your CNIC number (without dashes) and complete a security verification.
Once logged in, the system displays all mobile numbers registered under your CNIC, along with their respective network operators and registration dates. While the portal doesn’t explicitly show system numbers, it provides complete ownership verification and allows you to identify unauthorized registrations.
Method 2 – Check SIM Information via SMS (Code 668)
The simplest method for quick verification involves sending an SMS to 668. This PTA-managed service provides instant information about your SIM registration status. Simply compose a blank message or type “MIS” and send it to 668 from the SIM you want to verify.
Within moments, you’ll receive a response message containing your SIM registration status, the CNIC it’s registered under, and confirmation of whether the registration is active. This method works across all major networks including Jazz, Telenor, Zong, and Ufone.
The 668 code response helps you quickly verify that your SIM is properly registered and hasn’t been flagged for any issues. However, for more detailed information including system numbers and registration history, you’ll need to use online portals or contact your provider directly.
Method 3 – Mobile Network Portals (Jazz, Telenor, Zong, Ufone)
Each major network operator in Pakistan maintains its own customer service portal where subscribers can access detailed account information.
Jazz SIM Information Check Online: Visit the Jazz World app or website, log in with your mobile number, and navigate to the account details section. You can view registration information, linked CNIC, and request detailed records.
Telenor SIM Details by Number: The My Telenor app allows users to check their SIM registration status, view account details, and verify CNIC linkage directly from their smartphone.
Zong SIM Information System: Zong customers can use the My Zong app or dial customer service to verify their SIM details and ensure proper registration under the correct CNIC.
Ufone SIM Registration Check: Through the Ufone app or by visiting a franchise, customers can verify their SIM information and update registration details if necessary.
How to Find SIM Owner Details by System Number
Finding SIM owner details through a system number is subject to strict privacy laws in Pakistan. While you can verify ownership of SIMs registered under your own CNIC, checking someone else’s SIM information without authorization is prohibited.
The legal method to verify SIM ownership involves official channels only. If you need to verify a SIM for legitimate purposes (such as fraud reporting or legal proceedings), you must file a formal request with PTA or approach law enforcement agencies.
Personal information protection laws prevent unauthorized access to SIM registration data. Third-party websites or apps claiming to provide SIM owner details are typically scams or violate privacy regulations. Always use official PTA systems or your network operator’s authorized platforms.
How Many SIMs Are Registered on Your CNIC
The PTA provides a dedicated service called “Check SIMs on CNIC” to help citizens monitor all mobile connections registered under their national identity card. This system connects system numbers and CNIC records to provide a complete overview.
To use this service, visit the PTA website and access the Device Verification System section. Enter your CNIC number and complete the verification process. The system displays a comprehensive list of all active and inactive SIMs registered under your name, regardless of the network operator.
This verification is crucial because unauthorized SIM registrations can have serious consequences. Criminals sometimes fraudulently register SIMs using stolen or fake CNICs. Regular checks ensure your identity isn’t being misused for illegal activities.
| Network Provider | Verification Method | Response Time | Details Provided |

| Jazz | App/Portal/SMS | Instant | Registration status, CNIC, date |
| Telenor | App/SMS 668 | Instant | Ownership, registration details |
| Zong | App/Customer service | 1-24 hours | Complete account information |
| Ufone | App/Franchise | Instant | Registration and CNIC verification |
Common Problems and Solutions
System Number Not Found or Invalid
When your system number isn’t recognized, several factors could be responsible. The number might be incorrectly entered, or there could be a database synchronization delay. Always verify you’re using the correct format and haven’t included spaces or special characters.
If the error persists, contact your network operator’s customer service with your mobile number and CNIC for manual verification. They can cross-reference their internal database and update any discrepancies. In some cases, old or ported numbers may have outdated system number references that require administrative correction.
SIM Information Not Showing Online
Sometimes, properly registered SIMs don’t appear in online verification systems due to technical glitches or database update delays. This commonly occurs after recent SIM activations, number portability, or CNIC updates.
First, wait 24-48 hours as system updates aren’t always instantaneous. If information remains unavailable, visit your network’s franchise with your original CNIC and SIM purchase receipt. The franchise can manually verify your registration and escalate the issue to technical support if necessary.
Legal & Safety Tips for SIM Verification
Always avoid third-party applications claiming to provide SIM tracking or detailed owner information. These apps often harvest personal data or spread malware. Legitimate SIM verification only occurs through official PTA channels or authorized network operator platforms.
Never share your CNIC details, verification codes, or personal information with unknown websites or callers claiming to represent your network provider. Official representatives never ask for sensitive information through unsolicited calls or messages.
Data privacy guidelines in Pakistan protect your personal information. Only authorized personnel from PTA or your registered network operator can access your complete SIM details. Be cautious of phishing attempts and always verify the authenticity of websites before entering personal information.
Conclusion
Understanding how to check SIM information with system number empowers you to maintain control over your mobile identity and protect yourself from fraud. Whether you use the convenient 668 SMS service, the comprehensive PTA online portal, or your network operator’s dedicated app, regular verification ensures all your mobile connections are properly documented and secure.
The three main methods—system number verification, the 668 code, and CNIC-based checking—each serve different purposes but work together to provide complete oversight of your mobile registrations. Make it a habit to verify your SIM ownership quarterly, especially if you’ve recently changed your CNIC or updated personal information.
