CNIC Sims Information System: Check SIMs Registered on Your CNIC
See Every Mobile Number Linked to Your Identity — In Under a Minute
The system allows users to collect information about ID Card Numbers (CNIC) entered by visitors. By entering a CNIC and clicking 'Search,' users can access details such as the person's name, address, and the number of active SIM cards linked to that CNIC. In Pakistan, every mobile connection is associated with a CNIC, making it possible for people's identities to be tied to SIMs they did not request. The CNIC Sims Information System is the official PTA facility that lets you see exactly which SIMs are registered against your name, so nothing suspicious slips by unnoticed. Instead of relying on your mobile operator or a third party, you can check the count and network of every SIM tied to your CNIC in under a minute.
Online Portal
Visit PTA's official CNIC verification portal, enter your 13-digit CNIC number, and get an instant list of every SIM registered under your identity.

Understanding CNIC Data
Before checking SIM ownership, it helps to know exactly what CNIC Data covers and who's responsible for keeping it safe.
What is CNIC Data? CNIC Data is the complete set of personal, biometric, and family information linked to a Pakistani citizen's CNIC number. It is collected, stored, and managed by NADRA under the NADRA Ordinance, 2000.
What Information is Stored in CNIC Data?
- Full Name — legal name registered with NADRA.
- Father's/Husband's Name — used for identity and family record linking.
- CNIC Number — a unique 13-digit identifier.
- Date of Birth — verified against birth or family records.
- Gender — encoded in the CNIC number itself.
- Address — both permanent and current address.
- Photograph — captured at registration.
- Biometrics — fingerprints and now iris scans under NADRA's expanded 2026 framework.
- Family Registration Details — links to the Family Registration Certificate and family tree.
What Is the CNIC Sims Information System?
The CNIC Sims Information System is PTA's official platform for checking how many mobile SIM cards are currently registered against a given CNIC. It draws from the telecom industry's central subscriber verification database, which every operator in Pakistan — Jazz, Zong, Ufone, Telenor, and SCOM — is required to feed into.
The Role of PTA in SIM Registration
PTA regulates every mobile network operator in the country, and one of its core mandates is ensuring that no SIM reaches a customer without proper identity verification. Operators cannot activate a connection without confirming the buyer's fingerprint against NADRA's biometric records. Once a SIM is verified this way, it's logged against the owner's CNIC in the shared subscriber database — the same database this checking system queries.
Why the System Was Introduced
Before biometric verification became mandatory, SIM registration in Pakistan was loosely enforced. Fake or borrowed identity documents were often used to buy connections in bulk, and those unregistered or fraudulently registered SIMs became tools for scams, harassment calls, and other criminal activity. PTA introduced biometric verification and, alongside it, a public-facing check so ordinary citizens could audit their own records.
SIM Registration Regulations in Pakistan
Every SIM sale must go through biometric verification at the point of purchase. Operators are required to keep this data synced with PTA's central system, and CNIC numbers that are blacklisted, expired, or reported as lost by NADRA are automatically flagged, which can block new SIM issuance until the matter is resolved.
Benefits for Everyday Consumers
The system gives ordinary users a level of control that didn't exist a decade ago. You can confirm at a glance that your CNIC isn't attached to numbers you don't recognize, catch fraudulent registrations early, and keep a clean paper trail if you ever need to dispute a SIM linked to your identity — for a bank complaint, a police report, or simply peace of mind.

Check via Website
Open Numpk.com, enter your 13-digit CNIC number, click Search, and view your active SIM count by network — quick, fast, and accurate.
Check via SMS (668)
Open your SMS app, type your 13-digit CNIC number, and send it to 668. You'll get a reply showing SIMs registered against your CNIC on each network.
Why This Matters
Every SIM must be biometrically verified against a CNIC before activation. Checking regularly helps you catch unauthorized SIMs linked to your identity early.
Checking your SIM information regularly protects you from identity theft, fraud, and unauthorized SIM issuance.
How to Check SIMs Registered on Your CNIC Online
The online method through PTA's portal gives you a clearer, more detailed view than the SMS service, and it works from a phone browser or a desktop computer.
Open the Official SIM Information System
Go to the official portal at cnic.sims.pk in your browser. Double-check the spelling before entering any personal information — a number of look-alike websites exist that mimic PTA's design purely to harvest CNIC numbers, so only ever use the official domain.
Enter Your CNIC Number
Type your 13-digit CNIC number into the input field, without dashes (for example, 3520112345678 instead of 35201-1234567-8).
Complete Verification
Most portals require you to complete a simple human-verification check, such as a checkbox or captcha, before submission. This step exists to stop automated bots from mass-querying the database. Complete the check and click Submit.
View Registered SIMs
Once submitted, the portal displays a table showing the total number of SIMs linked to your CNIC, broken down by mobile operator (Jazz, Zong, Ufone, Telenor, and SCOM). Take a screenshot or save this page if you plan to file a complaint about any unrecognized numbers.
Mobile Instructions
On a smartphone, the process is identical — open your mobile browser, type the URL directly rather than tapping a link from social media or SMS, and follow the same four steps. The results table is usually mobile-responsive and easy to read on a small screen.
Desktop Instructions
On desktop, the layout is generally larger and easier to screenshot or print, which is useful if you're gathering evidence for a complaint or a bank dispute.
Common Mistakes Users Make
- ✕Typing the CNIC with dashes, which some versions of the portal reject
- ✕Visiting a spoofed or unofficial-looking domain instead of the verified PTA link
- ✕Submitting someone else's CNIC out of curiosity — the system is meant strictly for checking your own record
- ✕Assuming a single check is enough; unauthorized SIMs can appear at any time, so periodic checks matter more than a one-off look
How to Check SIMs Through SMS (668 Service)
If you don't have internet access, or you just want the fastest possible check, the SMS method works from any basic or smartphone on any network. For an internet-based alternative, you can also check anytime through numpk.com.
How the SMS Method Works
You send your CNIC number as a text message to the short code 668, and PTA's system replies with a breakdown of how many SIMs are registered against that CNIC, listed by operator.
Charges & Requirements
This service typically carries a small SMS charge (a couple of rupees plus tax, depending on your operator's rate), and it works from any registered SIM in Pakistan — no specific network, internet connection, or smartphone required.
Open Messaging App
Open the SMS app on your phone and start a new message.
Type Your CNIC
Enter your 13-digit CNIC number with no dashes or spaces (e.g., 4220112345678).
Send to 668
Send the message to the official PTA short code 668.
Wait for Reply
The automated reply usually arrives within a minute, though peak hours can occasionally delay it.
The reply message lists the total number of SIMs registered on your CNIC and typically breaks that number down operator by operator — for example, how many are with Jazz, how many with Zong, and so on.

Official Ways to Verify CNIC & How to Protect Your Data
01 Official Ways to Verify CNIC
Comprehensive CNIC information can only be obtained legally through official government portals and authorized institutions. Free self-check tools like ours can quickly show you your own SIM count, but full CNIC verification always goes through one of these official channels:
ID Verification
Pak-Identity portal, NADRA Registration Centers, and official SMS codes.
SIM Verification
SIM Information System for checking SIMs linked to your own CNIC.
Account Verification
Uses NADRA's Verisys system during account opening for real-time, authorized checks.
Internal Verification
Tax authorities and property registries verify CNIC details internally when processing applications.
02 How to Protect Your CNIC Data
1Never Share Copies Publicly
Never share copies of your CNIC publicly on social media or messaging apps.
2Mask Sensitive Information
Mask sensitive details, like your full CNIC number, when sharing for non-official purposes.
3Avoid Unknown Websites
Avoid unknown websites that ask you to enter your CNIC number for "verification" or "lookup."
4Verify Before Uploading
Confirm that any platform requesting your CNIC copy is an authorized institution.
5Use Official Platforms Only
Stick to NADRA's Pak-ID app and e-Sahulat centers — never third-party sites.
SIM Registration Rules and PTA Limits
PTA sets clear boundaries on how many SIMs a single person can hold, largely to prevent bulk fraudulent registration and to keep the subscriber database manageable and traceable.
Maximum SIMs Allowed Per CNIC
Current PTA policy caps the number of SIMs a single CNIC can hold per mobile operator, with an overall combined ceiling across all networks. These figures are adjusted from time to time by regulatory notification — if you're near the limit or unsure of the exact current cap, confirm directly with PTA's helpline or official website rather than relying on an older figure. You can also check your own SIM count anytime to stay ahead of the limit.
PTA Regulations
Every SIM issued must pass biometric verification against NADRA's records before activation. Operators are barred from activating a connection on a CNIC that NADRA has flagged as expired, blocked, or reported lost, and PTA can direct operators to suspend or de-register SIMs that violate these rules.
Biometric Verification Requirements
At the point of sale, the buyer's fingerprint is checked against their NADRA record in real time. A mismatch means the SIM simply won't activate — the core safeguard against someone registering a connection with just a photocopy of your CNIC, though it isn't a perfect shield against insider misuse at the point of sale.
When a CNIC is found holding more SIMs than the allowed limit, PTA generally follows a staged process:
Warning Notification
A warning is issued first, giving the CNIC holder a window to respond.
Service Restricted
Outgoing service on the excess SIMs may be restricted if unresolved.
SIMs Blocked
If the issue persists past the given window, the excess SIMs are blocked outright.
Deliberately registering SIMs using someone else's identity is also a criminal offense under Pakistan's cybercrime laws.
Network-Wise SIM Verification Guide
Each mobile operator in Pakistan offers its own additional verification tools beyond PTA's central system, which can be useful if you want operator-specific detail — such as exact registration dates or the status of a particular number.
Jazz SIM Verification
Jazz (which also operates the Warid brand) provides both an SMS-based biometric verification check and support through its call center. Customers can also use the Jazz World app to view details about numbers registered under their account. For anything beyond a basic count, Jazz's customer support line and franchise centers can pull up full registration details tied to your CNIC on their network.
Zong SIM Verification
Zong (CMPak) supports SIM ownership verification through its own short codes and customer service channels. Its helpline can confirm registration details for numbers under your CNIC on the Zong network, and franchise staff can assist in person if you need to dispute or block a number.
Ufone SIM Verification
Ufone offers verification through SMS codes and its customer care app, alongside standard helpline support. Customer care representatives can walk you through confirming which numbers on the Ufone network are tied to your identity.
Telenor SIM Verification
Telenor provides SIM registration confirmation through its own short codes, and its service centers can verify ownership details in person — particularly useful if you need documentation for a formal complaint.
SCOM SIM Verification
SCOM, which primarily serves Azad Jammu & Kashmir and Gilgit-Baltistan, follows the same PTA-mandated verification procedure. Because its footprint is smaller, verification is usually best handled directly through its customer service channels or nearby service centers rather than app-based self-service.
For any operator, if a number appears on your CNIC that you don't recognize, the fastest path to detail is calling that specific operator's helpline with the masked number from your 668 or portal result in hand.
How to Block Unauthorized SIMs Registered on Your CNIC
- Identify Suspicious SIMs: Compare your registered SIMs with the results from 668 or the portal. Treat any unaccounted SIMs as suspicious.
- Report to the Operator: Contact the operator of the unfamiliar number to formally disown the SIM, as they are required to investigate.
- Escalate to PTA: If the operator isn’t helpful, escalate the issue to the Pakistan Telecommunication Authority (PTA) through their helpline or online portal.
- Visit a Franchise or Service Center: For quicker resolution, visit the operator’s customer service center directly to initiate the disowning process.
- Required Documents: Bring your original CNIC for verification and a written complaint form or affidavit, if necessary, to confirm you didn’t register the SIM.
Benefits of CNIC Data Verification
- Detect unauthorized SIMs — many users discover unknown SIMs registered against their CNIC; checking your records regularly helps identify misuse early.
- Prevent fraud — scammers use illegally registered SIMs for scams, spam calls, or fake accounts, so monitoring your CNIC records improves security.
- Identity protection — your CNIC is linked with telecom registration systems, and keeping track of active SIMs helps protect your identity.
- Biometric verification awareness — PTA periodically updates biometric verification requirements, and users can verify whether their SIMs remain properly registered.
Common CNIC SIMs Information System Errors & Solutions
- Invalid CNIC Error: Ensure the CNIC is a clean 13-digit number without dashes, spaces, or incorrect digits.
- Verification Code Issues: Refresh the page, clear the browser cache, or switch browsers if verification fails. Ad blockers may cause conflicts.
- Website Not Loading: Try again later if the official portal is busy, or use the SMS method (668) as an alternative.
- SIM Count Not Displaying: Confirm the CNIC is correct and retry. If issues persist, it may be a database sync problem on PTA’s end; use SMS for verification.
- SMS Service Delays: Ensure your phone has a signal and the message was formatted correctly. Wait for a response before resending to avoid duplicate charges.
- General Tip: Use both methods (website and SMS) for cross-checking. If issues continue, contact PTA’s helpline for assistance.
Common CNIC SIMs Information System Errors & Solutions
- Invalid CNIC Error — usually means the CNIC was entered with dashes, extra spaces, or an incorrect number of digits. Re-enter it as a clean 13-digit number with no punctuation.
- Verification Code Not Working — if a captcha or verification step keeps failing, try refreshing the page fully, clearing your browser cache, or switching to a different browser. Ad blockers or privacy extensions occasionally interfere with these checks.
- Website Not Loading — the official portal can experience heavy traffic at peak times. Try again after a few minutes, or switch to the SMS method (668) as a reliable fallback that doesn't depend on the website being responsive.
- SIM Count Not Displaying — if the page loads but no results appear, double-check that your CNIC was entered correctly, then retry. If the issue persists across multiple attempts, it may be a temporary database sync issue on PTA's end — the SMS method is a good way to cross-check in the meantime.
- SMS Service Not Responding — if you don't get a reply from 668 within a few minutes, confirm your phone has signal and that the message was sent to the correct short code with no formatting errors. During high-traffic periods, replies can occasionally take longer than usual — wait before resending to avoid duplicate charges.
Security Tips to Protect Your CNIC from SIM Fraud
- Handle CNIC with Care: Treat your CNIC number and copies like a bank card; share only when necessary and clarify the purpose of the copy.
- Be Cautious of Scams: Never share CNIC details with unofficial vendors or unlicensed agents, and be wary of offers to check or register SIMs outside official channels.
- Safe Sharing: Provide your CNIC only to legitimate organizations like banks and government offices, avoiding unsecured channels for sharing.
- Regular Checks: Periodically verify your registered SIMs, similar to reviewing a credit report, to catch unauthorized registrations early.
- Report Suspicious Activity: Act promptly on unfamiliar calls or texts about SIMs; check through official channels and report any concerns immediately.
CNIC SIMs Information System vs SMS Method — Which Is Better?
Both methods pull from the same underlying database, so the core information — your SIM count by operator — will match either way. The real difference comes down to convenience and detail.
| Feature | Online System | SMS 668 |
|---|---|---|
| ⚡ Speed | Faster on a stable connection | Moderate, depends on network load |
| 📋 Details | More information, clearer formatting | Basic count and operator breakdown |
| 💰 Cost | Free | May apply (small SMS charge) |
| 📶 Accessibility | Requires internet | Works on any mobile phone |
Conclusion
Your CNIC is the anchor for every SIM registered in your name, which makes checking it periodically one of the simplest, most effective habits you can build for protecting your mobile identity in Pakistan. Whether you use the online portal at cnic.sims.pk or the quick SMS check to 668, the process takes only a minute and gives you clear visibility into exactly what's linked to your identity.
The real value isn't just in the one-off check — it's in catching problems early. An unauthorized SIM caught within days is a quick fix at a franchise counter; one discovered months later, after it's been used for fraud, can mean real legal and financial headaches. If you ever find a number you don't recognize, don't sit on it — report it to the relevant operator and, if needed, escalate to PTA directly.
Make It a Routine
Check your CNIC-linked SIMs every few months, keep your identity documents out of unnecessary hands, and treat any unexpected notice from your operator as a reason to check right away. It's a small habit that closes off one of the more common paths to identity misuse in Pakistan's mobile ecosystem.
