Every active SIM card in Pakistan is connected to a verified NADRA identity, so each mobile number carries a record of ownership. SIM owner details are the registration details linked to that number, such as the registered name, CNIC number, network operator, and activation status.
Whether you received a suspicious call, want to check a seller before buying a used phone, or simply need to confirm how many SIMs exist under your CNIC, knowing how SIM ownership works gives you control over your digital identity. The Pakistan Telecommunication Authority (PTA) lets every citizen check the SIMs on their own CNIC for free.
On this page you will learn what SIM owner details contain, how to check them, which networks are supported, and what to do if you discover unauthorized SIMs under your name. You can also use the free SIM search tool on this website.

1. What Are SIM Owner Details?
SIM owner details are the registration data linked to every active SIM card in Pakistan. When someone buys a new SIM, the operator records their full name and CNIC number and verifies their fingerprint through NADRA’s biometric system. As a result, every SIM is tied to a confirmed identity.
This became mandatory after PTA enforced biometric verification nationwide. Before that, SIMs could be bought anonymously. Today each SIM links to a verified citizen identity, which has greatly reduced telecom fraud, identity theft, and criminal misuse of prepaid numbers.
In simple terms, SIM owner details answer one question: who registered this mobile number? These records are held by the mobile operators under PTA’s rules.
2. What Information Do SIM Owner Details Include?
A SIM registration record typically contains:
| Field | What It Means |
|---|---|
| Owner full name | The name registered at activation, as it appears on the owner’s CNIC. |
| CNIC number | The 13-digit CNIC linked to the SIM through NADRA biometric verification. |
| Network operator | Jazz, Zong, Ufone, Telenor, or SCO. |
| SIM status | Whether the SIM is active, inactive, or blocked. |
| Registration address | The address recorded at the time of purchase. |
| SIM type | Prepaid, postpaid, or data-only. |
Important: SIM owner details never include call history, SMS logs, WhatsApp messages, live GPS location, or any private communication. These records are protected by Pakistan’s privacy laws, and only law enforcement agencies can access them through a formal legal process.
3. Why Should You Check SIM Owner Details?
Checking SIM ownership is a practical security habit that protects your identity, money, and personal safety.
Identify unknown callers
Spam calls and phone scams keep rising in Pakistan. When an unfamiliar number calls you repeatedly, looking it up helps you decide whether to answer, block, or report it. See our guide on how to trace unknown phone numbers safely.
Detect unauthorized SIMs on your CNIC
Criminals sometimes use stolen or photographed CNIC copies to register SIMs without the owner knowing. Regularly checking the SIMs on your CNIC helps you catch these before they cause financial or legal damage.
Verify before buying a used phone
Before buying a second-hand phone with a SIM, make sure the SIM is registered to the seller and is properly transferred to you at a franchise.
Confirm business contacts
Freelancers, traders, and small businesses often deal with unknown contacts. For significant deals, confirm the other person’s identity in person with their CNIC.
Stay within PTA’s SIM limit
PTA limits how many SIMs can be registered on one CNIC (currently 5 voice SIMs and 3 data-only SIMs across all networks). If you exceed the limit, newer SIMs may be blocked, so periodic checks help you stay compliant.
4. How to Check SIM Owner Details Online
Our free SIM search tool works for all Pakistani networks:
- Enter the number: open the search page and type the 11-digit mobile number, or switch to CNIC and enter a 13-digit CNIC number.
- Click Search Now: the tool checks the number against our data provider’s records.
- View the results: any matching record is shown, such as the registered name, network, and status.
Please note: SIM Owner Details is an independent website and is not affiliated with PTA, NADRA, or any mobile operator. Results come from third-party sources, may be incomplete or out of date, and should be used only for lawful, personal safety purposes. For official records, use the PTA methods below.
Tip: Bookmark the search page in your phone’s browser so you can look up a suspicious number in seconds without installing anything.
5. Official PTA Methods to Verify SIM Ownership
PTA and the mobile operators provide three official ways to check the SIMs registered on your own CNIC.
Method 1: SMS to 668
Type your 13-digit CNIC number without dashes and send it to 668. You will receive the total number of SIMs registered on your CNIC, broken down by network.
Method 2: PTA SIM Information System
Visit cnic.sims.pk, enter your CNIC, complete the verification, and click search. The portal shows your registered SIM count per network.
Method 3: Visit a Telecom Franchise
The two methods above show how many SIMs are registered, not the actual numbers. To see the exact numbers, visit each operator’s franchise (Jazz, Zong, Ufone, or Telenor) with your original CNIC. After fingerprint verification, the representative can show the numbers registered on your CNIC, with their activation dates and status.
Note: Each network keeps its own records, so you need to visit each operator’s franchise separately.

6. Supported Mobile Networks
Pakistan has five PTA-licensed mobile network operators:
- Jazz — the largest subscriber base, covering major cities and rural areas.
- Zong — known for wide 4G data coverage.
- Ufone — stable voice connectivity with affordable packages.
- Telenor — strong coverage in remote and northern regions.
- SCO — the Special Communications Organization, serving Azad Jammu & Kashmir and Gilgit-Baltistan.
The official checks (668, cnic.sims.pk, and franchise visits) cover the SIMs registered on your CNIC across these networks.
7. SIM Owner Details vs Live GPS Tracking
Many people confuse SIM owner details with live GPS tracking, but they are completely different:
| Feature | SIM Owner Details | Live GPS Tracking |
|---|---|---|
| Data source | SIM registration records | GPS satellites and device sensors |
| Shows location? | No — at most a registration address | Yes — real-time position |
| Needs device access? | No | Yes — an app on the device |
| Consent | Use only for lawful, personal safety purposes | Only with the device owner’s consent |
| Shows owner name? | Yes | No |
| Cost | Free | Varies (many apps need a subscription) |
In short, SIM owner details are about who registered a number, while GPS tracking shows where a device is. Tools like Google Find My Device handle locating your own phone; no legitimate service can show a stranger’s live location from a phone number.
8. Is Checking SIM Owner Details Legal in Pakistan?
Checking the SIMs registered on your own CNIC is completely legal. PTA provides the 668 SMS service and the SIM Information System specifically for this.
Personal information about other people is different. Under Section 16 of the Prevention of Electronic Crimes Act (PECA) 2016, obtaining, sharing, or using another person’s identity information without authorization is an offence. Using SIM details to harass, stalk, defraud, or threaten anyone is a crime, investigated by the National Cyber Crime Investigation Agency (NCCIA), with penalties that include imprisonment and fines.
Bottom line: Check SIM details for your own protection. Never use anyone’s information to harm, intimidate, or deceive them. If someone is harassing or defrauding you, report them through official channels and let the authorities identify them.
9. What to Do If You Find Unauthorized SIMs
A SIM on your CNIC that you never bought is serious, because it could be used for scams or illegal activity that traces back to you. Act immediately:
Step 1: Confirm through 668
Send your CNIC to 668 and compare the SIM count per network with the SIMs you actually own. Any mismatch signals an unauthorized registration.
Step 2: Visit the operator’s franchise
Go to the franchise of the network where the unknown SIM exists, with your original CNIC. Ask to see all numbers registered on your CNIC and request immediate deactivation of any you don’t recognize.
Step 3: File a PTA complaint
Call PTA’s toll-free helpline 0800-55055, or file a complaint through PTA’s official website or mobile app.
Step 4: Report to NCCIA if needed
If the SIM may have been used for fraud or other crimes, report it to NCCIA (helpline 1799) at complaint.nccia.gov.pk.
Don’t delay. The longer an unauthorized SIM stays active on your CNIC, the greater your legal and financial risk. Block it first, then investigate.
10. How to Protect Your SIM Identity
Check your SIMs monthly
Send your CNIC to 668 at the start of every month. This quick habit lets you catch unauthorized registrations early. See how a 668 check stops fraud.
Never share your CNIC photo
Most SIM fraud starts with a leaked CNIC image. Don’t send your CNIC photo over WhatsApp, email, or social media, especially for “job offers”, prize schemes, or loan offers — the most common tricks scammers use.
Buy only from biometric retailers
Only buy SIMs from authorized retailers who verify your fingerprint. SIMs sold without biometric verification are illegal and can be blocked at any time.
Register SIMs under your own CNIC only
Registering a SIM on someone else’s CNIC, even a family member’s, makes them legally responsible for it. Every adult should use SIMs registered in their own name.
Deactivate unused SIMs
Old SIMs you no longer use still count toward your PTA limit and can be misused. Visit your operator’s franchise and formally deactivate any SIM you don’t need.
