SIM Owner Details

Here’s what a complete SIM registration record contains:

• Full name — exactly as it appears on your CNIC issued by NADRA
• CNIC number — the 13-digit national identity number linked to the SIM
• Network operator — whether it’s Jazz, Zong, Telenor, Ufone, or SCOM
• Activation date — the exact date the SIM was first registered
• Registered address — the address provided during biometric verification
• SIM status — whether the number is currently active, blocked, or deactivated

The only legitimate way to check SIM owner details is through the official methods outlined below.

Why Checking SIM Owner Details Matters More Than You Think

Most people only think about checking their SIM registration when something goes wrong — a strange call from a bank they don’t use, a message about a loan they never applied for, or worse, a visit from law enforcement about a number they’ve never seen.

By then, the damage is already done.

The Scale of Unauthorized SIM Registration in Pakistan

Pakistan’s telecom fraud problem isn’t some edge case. PTA detected millions of unauthorized SIM registrations in recent years, and the victims — ordinary Pakistanis who never activated those SIMs — have collectively lost billions in financial fraud.

The most common scenarios where unauthorized SIMs cause real harm:

Identity theft and financial fraud — Criminals register SIMs on stolen CNICs and use them to open JazzCash or Easypaisa accounts, apply for microloans, or receive fraud proceeds. The money trail leads back to your CNIC.

Banking two-factor authentication bypass — If someone has a SIM registered on your CNIC and knows your bank details, they can intercept OTP codes meant for your accounts. SIM swap attacks have surged dramatically across Pakistan between 2024 and 2025.

Wrongful police investigations — When a crime is committed using a mobile number, law enforcement traces the SIM’s CNIC registration first. If that SIM is on your name, you become the first person investigated — even if you’ve never touched that phone.

Unexpected SIM blocking during PTA drives — PTA periodically runs re-verification campaigns. If unverified SIMs exist on your CNIC, your own legitimate numbers can get caught in the crossfire and blocked without individual notice.

Legal liability you didn’t ask for — Pakistani law doesn’t care whether you personally activated a SIM. If it’s registered on your CNIC, you’re legally accountable for everything done with that number.

The only way to catch these problems early is to check your SIM owner details regularly through official PTA channels.

How to Check SIM Owner Details in Pakistan — All Official Methods

Pakistan offers several free and low-cost ways to verify SIM registration. Each method serves a slightly different purpose, and knowing which one to use — and when — is the difference between a quick check and a thorough identity audit.

Method 1: SMS to 668 — Full CNIC SIM Audit

This is the single most powerful SIM check available to any Pakistani citizen. One SMS to 668 reveals every SIM registered on your CNIC across all five operators — Jazz, Zong, Telenor, Ufone, and SCOM — simultaneously. No internet required. Works on any phone, including basic feature phones.

How to check SIM owner details via 668:

1. Open your SMS app on any Pakistani mobile phone
2. Type your 13-digit CNIC number — no dashes, no spaces (example: 3520112345671)
3. Send the message to 668
4. Receive a reply within 5–30 seconds

What the reply looks like:

The response will list the number of active SIMs per operator. For example:

Total SIMs Registered: 4 Jazz / Mobilink: 2 SIMs Zong (CMPak): 1 SIM Telenor Pakistan: 1 SIM Ufone (PTCL): 0 SIMs SCOM: 0 SIMs

If the total count is higher than the number of SIMs you personally own, unauthorized SIMs are active on your CNIC. Don’t wait — follow the emergency steps in the section below.

668 at a glance:

Important note: 668 shows you how many SIMs are registered per operator — it does not display individual mobile numbers. To get specific number details, you’ll need to visit your operator’s franchise with your original CNIC.

For a complete walkthrough on checking all SIMs linked to your CNIC, including what to do if the count doesn’t match, read our detailed guide on how to check SIMs on CNIC in Pakistan.

Method 2: Send MNP to 667 — Verify a Specific SIM in Your Hand

While 668 gives you the big picture, 667 is your tool for verifying one specific SIM card. It returns the registered owner name, partially masked CNIC, and network operator for the SIM currently inserted in your phone.

How to check SIM owner details via 667:

1. Insert the SIM you want to verify into your phone
2. Open your messaging app
3. Type MNP in capital letters
4. Send the message to 667
5. Receive the owner name, masked CNIC, and network within 5–10 seconds

Best for: Second-hand phones, suspicious SIMs you’ve found, verifying your own registration status, or checking a SIM before purchasing a used device.

667 at a glance:

Critical limitation: 667 works exclusively for the SIM physically in your phone at that moment. You cannot use it to remotely look up another person’s number — and no official channel in Pakistan allows this.

The key difference between 668 and 667: Use 668 to see the full picture of everything registered on your CNIC. Use 667 when you have a SIM physically in your hand and need to confirm its registration details. For complete protection, use both.

Method 3: PTA Official Portal — cnic.sims.pk

PTA’s free web portal delivers the same information as 668 but without any SMS charge. It also shows exact registration dates and provides a visual, operator-by-operator breakdown that you can print or screenshot.

How to check SIM owner details via cnic.sims.pk:

1. Open any browser on your mobile phone or computer
2. Visit cnic.sims.pk
3. Enter your 13-digit CNIC number
4. Complete the CAPTCHA security verification
5. View your complete SIM registration list with network names and dates

Why use this over SMS: The portal shows exact registration dates for each SIM, gives you a clean visual breakdown by network, and — most importantly — produces printable documentation. This is significant because PTA portal records are officially accepted by courts, police stations, and banks for FIR filing, fraud reports, and legal proceedings.

If you regularly audit your SIM identity (and you should), the portal is the most cost-effective method since it’s completely free. For users who prefer the SMS route, 668 delivers the same core data — the portal simply adds more detail and documentation capability.

Method 4: Official Network Apps

Every major Pakistani telecom operator offers a free mobile app that lets you check your SIM registration status and manage your account directly from your smartphone.

All four apps are free on Google Play and the App Store. Beyond basic SIM checks, these apps also send push notifications for account changes and SIM status updates — giving you real-time awareness without having to manually check every few weeks.

For operator-specific SIM verification methods, we’ve written detailed guides for each network:

• Jazz SIM Owner Details — 5 Official Methods
• Check Telenor SIM Owner Details
• How to Check Ufone SIM Owner Details
• SIM Owner Details by Network — All Operators

Method 5: Network-Specific USSD and SMS Codes

Beyond the universal PTA codes, each operator has its own dedicated verification codes that work directly from your SIM:

These USSD codes return your own number’s account status and basic registration details instantly and free of charge. They’re particularly useful for a quick self-check when you don’t need the full CNIC-wide audit that 668 provides.

Method 6: 76367 — Identify Which Network a Number Belongs To

Before checking SIM owner details through any operator-specific channel, you sometimes need to know which network a number belongs to — especially for numbers that have been ported through MNP (Mobile Number Portability).

How to use 76367:

1. Open your SMS app
2. Type the 11-digit mobile number (starting with 03) you want to identify
3. Send to 76367
4. Receive the network name within seconds

This is particularly useful when 668 shows an unknown SIM on your CNIC and you need to identify the operator before calling their helpline to get it blocked.

PTA SIM Registration Rules Every Pakistani Should Know

Pakistan’s telecom regulations are designed to prevent identity fraud and ensure every active SIM is traceable to a real, verified individual. Here are the core rules:

The 5-voice-SIM limit is a total across all networks combined. You can split them in any combination — say, 2 Jazz, 1 Zong, 1 Telenor, 1 Ufone — but the combined count cannot exceed 5. The 3 data-only SIM slots are separate and meant for MBB devices or tablets.

If 668 or cnic.sims.pk shows more active SIMs than you personally own, that’s a red flag. Take immediate action.

For a complete breakdown of PTA’s SIM limits and how to handle excess SIMs, visit our CNIC SIM count and limits guide.

Found an Unauthorized SIM on Your CNIC? Do This Immediately

If your 668 reply or cnic.sims.pk portal shows more SIMs than you registered, don’t assume it’s a glitch. Treat it as a security incident and act fast.

Step 1: Identify the operator — Note the network name from the 668 reply. This tells you which company issued the unauthorized SIM.

Step 2: Call the operator’s helpline

Step 3: Request emergency SIM block — Provide your CNIC and explain that a SIM was registered without your authorization. Ask for an immediate block.

Step 4: Visit the nearest franchise — Bring your original CNIC for in-person biometric verification and permanent blocking of the unauthorized SIM.

Step 5: File a PTA complaint — Use PTA’s complaint portal at pta.gov.pk or call the free helpline at 0800-55055. PTA can coordinate directly with the operator for forced biometric deactivation.

Step 6: Secure your bank accounts — Notify your bank that your CNIC may have been compromised. If the unauthorized SIM was used to register a mobile wallet (JazzCash, Easypaisa), contact those services immediately to freeze any accounts opened on your identity.

Do not rely on third-party apps, unofficial websites, or any service claiming to “fix” your CNIC data remotely. Every legitimate deactivation step happens through your operator and PTA directly.

For a step-by-step deactivation walkthrough, read our guide on how to check and handle blocked SIMs on your CNIC.

What SIM Owner Details Can — and Cannot — Tell You

This is one of the most misunderstood parts of SIM verification in Pakistan. Dozens of websites make inflated promises about what you can find by entering a mobile number. Here’s the honest, PTA-aligned reality:

If a website or app promises capabilities from the top three rows of this table, it’s either fabricating data or violating Pakistani law — and using it exposes you to legal consequences under PECA 2016.

For more on what’s legally possible, see our SIM ownership in Pakistan guide.

Is It Legal to Check SIM Owner Details in Pakistan?

Yes — with one critical boundary.

Under Pakistani law, including the Prevention of Electronic Crimes Act 2016 (PECA) and PTA regulations, you are fully permitted to check SIM owner details for SIMs registered against your own CNIC. The 668 SMS service, 667 code, and cnic.sims.pk portal are specifically designed for this purpose.

What is not permitted — under any circumstance — is accessing another person’s SIM registration data without legal authority. This isn’t a grey area. PTA has blocked over 1,300 websites and apps that illegally sold or displayed SIM and CNIC data, and the Federal Investigation Agency (FIA) actively prosecutes both the operators of such services and individuals who use them.

Here’s what PECA specifically says:

Criminal liability applies to everyone involved — not just the website owner. If you use a service that claims to show you another person’s full SIM owner details, you are legally at risk.

The only safe path is through official channels: PTA’s 668, cnic.sims.pk, 667, or your operator’s franchise.

Fresh SIM Data vs. Outdated Records — Why It Matters

When we talk about SIM owner details in Pakistan, what we’re really asking for is fresh SIM data — the current, real-time registration information held in PTA’s national telecom database, updated through mandatory biometric verification.

The distinction matters because outdated records can mislead you. A SIM that was registered on your CNIC six months ago might have since been transferred, deactivated, or re-verified under a different identity. Checking through official channels — 668, cnic.sims.pk, or 667 — always pulls from PTA’s live database, giving you the most current registration snapshot available.

Special Cases: CNIC-Based SIM Checks

Checking SIM Owner Details Using Your CNIC Number

Your CNIC is the master key to your telecom identity in Pakistan. Every SIM registered in your name is linked to your 13-digit CNIC number through NADRA’s biometric verification system.

If you want to see the complete picture of what’s registered on your identity — across Jazz, Zong, Telenor, Ufone, and SCOM — the CNIC-based check via 668 or cnic.sims.pk is the only way to get it.

We’ve covered this process in full detail, including screenshots, troubleshooting, and what to do with unexpected results, in our dedicated CNIC SIM check guide.

SIM Information for Specific Use Cases

Different situations call for different verification methods. Whether you’re buying a used phone, received a SIM you didn’t activate, or need to file a formal complaint, we’ve organized the right approach for each scenario in our SIM information resource page.

About SIM Owner Details APK Apps — A Warning

Search “SIM owner details” on Google Play and you’ll find dozens of APK apps promising to reveal anyone’s name, address, and CNIC by entering their mobile number. Here’s what you need to know about these apps:

They don’t work. No third-party app has access to PTA’s SIM registration database. The data they show is either fabricated, pulled from outdated public directories, or simply generated to look convincing.

Many of these apps also pose privacy and security risks — requesting unnecessary permissions (contacts, storage, location) and potentially harvesting your own data in the process.

The only reliable way to check SIM owner details is through the official PTA channels covered in this guide. If you’ve been using one of these apps, we recommend uninstalling it and running a security check on your device.

For more on why these apps are unreliable and potentially dangerous, read our SIM owner details APK guide.

Overseas Pakistanis: How to Check and Manage SIM Owner Details from Abroad

If you’re living abroad and need to check what SIMs are registered on your CNIC, your options are more limited but still available:

cnic.sims.pk — Accessible from anywhere in the world through any browser. Enter your CNIC and get your full SIM registration list.

Operator apps — Jazz World, My Zong, My Telenor, and My Ufone apps work internationally if you have an active account.

Franchise visit via authorized representative — If you need to deactivate unauthorized SIMs, you can authorize a family member in Pakistan to visit the operator’s franchise with your original CNIC and a notarized authorization letter.

PTA complaint portal — pta.gov.pk accepts complaints from any location. For urgent cases, the 0800-55055 helpline is accessible from Pakistani numbers only, but the web complaint form works globally.

Managing your SIM identity from abroad requires extra vigilance since you can’t easily visit a franchise for biometric verification. Regular cnic.sims.pk checks — at least quarterly — are the minimum recommended frequency for overseas Pakistanis.

Frequently Asked Questions About SIM Owner Details

What is the fastest way to check SIM owner details in Pakistan? Send your 13-digit CNIC number (without dashes) to 668 via SMS. You’ll receive a count of active SIMs per operator within seconds. The free alternative is cnic.sims.pk — same data, no SMS cost.

Can I check SIM owner details of someone else’s number? No. Pakistani telecom law does not permit third-party lookups. You can only check SIMs registered on your own CNIC, or verify a SIM physically in your own device using 667.

What does 667 return when I send MNP to it? 667 returns the registered owner’s name, partial CNIC digits, and activation date of the SIM currently inserted in your phone. It does not work for remote number lookups.

Is cnic.sims.pk an official PTA website? Yes. It is Pakistan Telecommunication Authority’s official consumer portal for checking SIM registration against your CNIC at zero cost.

How many SIMs can one CNIC hold? PTA allows a maximum of 8 SIMs per CNIC — 5 voice SIMs and 3 data-only SIMs — across all operators combined. If 668 shows more SIMs than you own, report immediately.

What should I do if 668 shows a SIM I never registered? Call the operator whose name appears in the reply, visit their franchise with your original CNIC, and file a complaint with PTA at 0800-55055 for biometric-based forced deactivation.

Is the 668 service free? No. PTA’s 668 SMS costs Rs. 2 + applicable taxes per message. The free equivalent is cnic.sims.pk.

What does 76367 do? It identifies which mobile network a Pakistani number belongs to — useful for ported numbers where the original network code no longer matches the current operator.

Can websites that show “live SIM tracker” results be trusted? No. No public-facing live SIM tracking service exists in Pakistan. Any site offering this is fabricating results and may be harvesting your data.

Where can I learn more about specific operator checks? We’ve published detailed guides for each network: Jazz SIM owner details, Telenor SIM owner details, Ufone SIM owner details, and our complete SIM owner details by network overview.
