Every 6 minutes, a Pakistani loses money because criminals registered a mobile SIM on their CNIC without consent. In 2025 alone, PTA detected 4.7 million unauthorized SIM registrations nationwide. Victims faced frozen bank accounts, police investigations, wrongful detentions, and years of legal battles — all over SIMs they never activated.

The good news? You can check every SIM registered on your CNIC in 30 seconds, completely free, using official PTA methods.

This is Pakistan’s most complete guide to checking SIM owner details — covering every official method, every network, all USSD codes, biometric verification, blocking steps, fraud prevention, and every security measure you need in 2026.

⚡ Quick Start — Check Your SIM Details Right Now

All five methods are 100% official, PTA-verified, and permanently free. No registration. No payment. No third-party apps.

📋 What Are SIM Owner Details?

SIM owner details are the verified registration records permanently linked to every SIM card in Pakistan. When a SIM is activated, the telecom operator records specific data points stored in PTA’s central database and cross-verified with NADRA’s national identity records.

What SIM owner details include:

• Registered owner’s full name

• CNIC number (13-digit, NADRA-verified)

• Registration address at time of SIM activation

• SIM activation date

• Network operator (Jazz, Zong, Telenor, Ufone, SCOM/SCO)

• Biometric Verification Status — verified or unverified

• Mobile number (MSISDN)

• Device IMEI linked at registration

Every SIM in Pakistan is permanently linked to a CNIC through NADRA’s Multi-Finger Biometric Verification System (MBVS). The MBVS database covers 127 million+ Pakistani citizens and uses live-finger detection to prevent fake or forced registrations. No SIM can be legally activated in your name without your fingerprint confirmation.

Under Pakistani telecommunications law — including PECA 2016 and PTA Telecom Regulations 2021 — the CNIC holder is legally responsible for ALL activities conducted on SIMs registered under their identity, even if they never registered or used those SIMs themselves.

⚠️ This is why checking your SIM owner details is not optional. It is a legal and financial necessity.

📱 Method 1 — How to Check via 668 SMS (Most Comprehensive)

The 668 method is the most complete free SIM check in Pakistan. It shows every SIM registered across all five Pakistani networks simultaneously — no internet needed, works on any phone including basic feature phones.

Step-by-Step: 668 Method

Example: If your CNIC is 35201-1234567-1, type 3520112345671 and send to 668.

Sample 668 Reply:

✅ Cost: FREE | ✅ Internet: Not required | ✅ Works on: Every phone | ✅ Response: 5–30 seconds

🚩 Red Flag: If the number shown is higher than the SIMs you personally registered, unauthorized registration has occurred. Go directly to Section 10 (Blocking) below.

📲 Method 2 — How to Check via 667 MNP (Fastest — 5 Seconds)

The 667 MNP method is the fastest SIM verification in Pakistan — results in 5 to 10 seconds. Unlike 668 (which shows your total count by CNIC), the 667 method tells you who owns one specific SIM currently inserted in your phone.

Step-by-Step: 667 Method

Sample Reply:

✅ Cost: FREE | ✅ Response: 5–10 seconds | ✅ Internet: Not required

When to use 667 instead of 668:

• You bought a second-hand phone and want to verify the SIM inside

• You found an unknown SIM and want to identify the owner

• You want to confirm your own SIM is correctly registered in your name

• You received a SIM from someone and want to verify it before use

• You want to check if a SIM was ported without your consent (MNP fraud check)

🌐 Method 3 — How to Check via cnic.sims.pk Portal (Most Detailed)

cnic.sims.pk is PTA’s official free online portal. It provides the most detailed breakdown of all SIMs on your CNIC — including exact registration dates, which the SMS methods do not provide.

Step-by-Step: cnic.sims.pk

1. Open your browser and go to cnic.sims.pk

2. Enter your 13-digit CNIC in the input field

3. Complete the security verification (CAPTCHA)

4. Click Submit

5. View your complete operator-wise SIM breakdown

6. Print or screenshot the result for official records

✅ Cost: FREE | ✅ Best for: Court documentation, bank disputes, police FIR | ✅ Shows exact registration dates

Why use cnic.sims.pk over SMS methods:

• Results are printable — accepted by courts, banks, and police stations

• Shows registration date for each SIM (SMS methods do not)

• Works from any internet-connected device — including internationally

• Visual display — easier to screenshot and submit as evidence

• Accessible from laptop, tablet, or smartphone browser

🔄 Method 4 — USSD Codes for Network-Specific SIM Check

USSD codes let you check SIM registrations directly on specific networks from your phone keypad — no internet, no app, no charges.

📊 667 vs 668 vs cnic.sims.pk — Which to Use When

Simple decision rule:

• Want to know who owns a specific SIM? → Use 667

🔐 Biometric Verification System (BVS) — How It Secures Every SIM

Every SIM in Pakistan must be biometrically verified through NADRA’s Multi-Finger Biometric Verification System (MBVS) before full activation. Unverified SIMs face automatic progressive blocking.

How MBVS Works:

1. Customer places finger on biometric scanner at franchise

2. Live-finger detection confirms a real person (not prosthetic or fake)

3. NADRA’s database of 127M+ fingerprints is queried in real time

4. Digital verification certificate is generated and sent to PTA

5. SIM is activated only after PTA receives the MBVS certificate

Check Your BVS Status — All Free

⚠️ If “Not Verified”: Visit the nearest operator franchise immediately with your original CNIC. Biometric re-verification is completely free.

⚙️ DIRBS — PTA’s Automated SIM Enforcement System

DIRBS (Device Identification, Registration and Blocking System) is PTA’s 24/7 automated enforcement engine. It monitors every SIM and device on Pakistani networks and blocks non-compliant registrations automatically — no human intervention, no prior warning.

What Triggers DIRBS Auto-Blocking

🔴 Critical Risk: Criminals registering SIMs using your stolen CNIC can push your total count past the legal limit. DIRBS then automatically blocks your legitimate SIM — not the criminal’s. Monthly 668 checks are your only protection.

🔢 SIM Registration Limits Per CNIC in Pakistan

When limits are exceeded, DIRBS auto-blocks the excess SIM immediately. If criminals push your CNIC past the limit, DIRBS may block your legitimate SIM — not theirs.

🚫 How to Block Unauthorized SIMs — Complete Step-by-Step

Discovered unauthorized SIMs on your 668 check? Act immediately. Every day those SIMs operate under your identity.

⚠️ CRITICAL: SIM blocking CANNOT be done online or by phone. Pakistani law requires an in-person franchise visit with biometric verification — mandatory, no exceptions.

Step 1 — Document Everything First

• Screenshot your 668 result with full date and time stamp

• List every SIM number you personally own and actively use

• Identify which SIMs you did NOT register

• Save all screenshots — required for police FIR and PTA complaints

Step 2 — Visit Each Operator’s Franchise In Person

• Bring: Original CNIC only (no photocopies accepted)

• Say at counter: “I want to file a SIM disowning request for unauthorized registrations on my CNIC”

• Complete biometric fingerprint verification

• Fill and sign the disowning form listing all unauthorized numbers

• Collect your reference number

• Receive written confirmation receipt

  You must visit each operator’s franchise separately.

Step 3 — Blocking Timeline

Step 4 — Escalate If Needed

Once a SIM is biometrically disowned, it is permanently blocked and cannot be reactivated by anyone — not the operator, not the fraudster, not even you.

🔁 SIM Ownership Transfer — Complete Process

Transferring a SIM from one person to another requires both parties physically present at the franchise simultaneously. No remote or online transfer is permitted under PTA regulations.

Personal SIM Transfer Requirements:

• Both parties visit the same franchise simultaneously

• Current owner’s original CNIC

• New owner’s original CNIC

• Both complete biometric fingerprint re-registration at the counter

• Fee: Rs. 100 to Rs. 300 per SIM

• Processing: 24 to 48 business hours

  ℹ️ Deceased owner: Legal heir must present death certificate, inheritance documents, and original CNIC. Court succession certificate may be required.

Corporate SIM Transfer Requirements:

Visit the operator’s Corporate Services Center (NOT a regular franchise) with:

• NTN certificate of the company

• Board Resolution letter authorizing the representative

• Representative’s original CNIC

• New user’s original CNIC (for employee reassignment)

• Fee: Rs. 100 to Rs. 300 per SIM | Processing: 24 to 48 business hours

🏢 Corporate SIM Verification — NTN-Based Registration

⚠️ Important: The 667, 668, and cnic.sims.pk methods do NOT work for corporate SIMs registered under an NTN (National Tax Number).

Corporate SIM verification requires a visit to the operator’s Corporate Services Center with:

1. NTN certificate of the company

2. Board Resolution authorizing the visit and representative

3. Representative’s original CNIC

Employee SIM management: When an employee leaves or changes roles, both the company representative and the employee must visit together to complete biometric re-registration. Processing: 24–48 business hours. Fee: Rs. 100–Rs. 300 per SIM.

🛡️ SIM Fraud Prevention — Your Complete 6-Step Security Plan

Pakistanis lost Rs. 22.3 billion to SIM-related fraud in 2025. SIM swap attacks surged 127% between 2024 and 2025. Here is your complete protection plan.

How SIM Swap Fraud Works

A fraudster obtains your CNIC details through a photocopy, data breach, or social engineering. They visit an operator franchise claiming your SIM is lost. Using your details, they request a replacement SIM. Once active, they intercept every OTP sent to your number — banking, JazzCash, Easypaisa, email, WhatsApp. By the time you notice your phone has lost signal, the damage is already done.

Step 1 — Monthly CNIC Verification

Send your CNIC to 668 on the 1st of every month. Screenshot and date-stamp every result. If the SIM count increases from last month, investigate immediately. This single habit detects 68% of identity theft cases before serious damage occurs.

Step 2 — Protect Your Physical CNIC

Write “FOR [PURPOSE] ONLY — NOT VALID FOR SIM REGISTRATION — [DATE]” across every CNIC photocopy before handing it to anyone. Never store your CNIC photo in WhatsApp, phone gallery, email, or cloud backup. Report a lost or stolen CNIC to police and NADRA within 24 hours.

Step 3 — Buy SIMs from Authorized Franchises Only

Never purchase pre-registered SIMs from street vendors or unknown sources. Always witness your own biometric registration process. Verify your 668 count within 24 hours of buying any new SIM.

Step 4 — Switch from SMS-OTP to Authenticator Apps

SMS-based OTP is your biggest vulnerability to SIM swap. Switch banking apps, email, and mobile wallets to Google Authenticator or Microsoft Authenticator. Authenticator apps work locally — no SIM required, immune to SIM swap attacks.

Step 5 — Monitor Financial Accounts Weekly

Enable transaction alerts on every bank account, JazzCash wallet, and Easypaisa account. Check statements weekly. If unauthorized activity is detected: freeze accounts immediately, change all passwords, check 668, and call FIA Cyber Crime at 1991.

Step 6 — Educate Your Entire Family

Teach every family member to never share OTP with any caller for any reason, check 668 monthly, and recognize common scam scripts. Families with security awareness prevent 89% of common SIM fraud attempts.
