Understanding SIM Registration in Pakistan

Before diving into the how-to, it helps to understand the system you’re working with.

Every SIM card sold in Pakistan must be registered against a Computerized National Identity Card (CNIC) through biometric verification—typically a fingerprint scan at the point of sale. This requirement, enforced by the Pakistan Telecommunication Authority (PTA), exists for national security and fraud prevention purposes.

The system creates two important capabilities for citizens:

  • Self-verification: You can check how many SIMs are registered against your own CNIC at any time
  • Limited third-party information: You cannot directly access another person’s SIM owner details without legal authority

This distinction matters. While you can fully audit your own SIM registrations, checking someone else’s details requires going through proper channels—typically law enforcement or court orders.


Method 1: PTA’s SIM Information System (SIS) via SMS

The fastest way to check SIMs registered on your CNIC is through PTA’s official SMS service. It takes about 30 seconds and works on any mobile phone.

Step-by-Step Process

  1. Open your messaging app on any phone (doesn’t need to be a smartphone)
  2. Type your CNIC number in the message body—use the 13-digit format without dashes (e.g., 3520212345678)
  3. Send the SMS to 668
  4. Wait for the reply—typically arrives within 1-2 minutes

Understanding Your Results

The reply message will list:

  • Total number of SIMs registered against your CNIC
  • Breakdown by mobile network operator (Jazz, Telenor, Zong, Ufone, SCOM)
  • The specific mobile numbers registered under each operator

Example response:

Total SIMs: 4Jazz: 2 (0300-1234567, 0301-7654321)Telenor: 1 (0345-9876543)Zong: 1 (0311-1112222)Ufone: 0SCOM: 0

Important Notes

  • SMS charges: Standard SMS rates apply (typically Rs. 2-3)
  • Network coverage: Works even in areas with poor data connectivity since it uses SMS
  • Frequency limits: No official limit, but avoid excessive checking to prevent being flagged as spam
  • Response delays: During peak hours or system maintenance, responses may take up to 5 minutes

Method 2: PTA Online Portal (DIRBS System)

For a more detailed view, PTA offers an online verification system through their Device Identification Registration and Blocking System (DIRBS) portal.

Step-by-Step Process

  1. Visit the official PTA website: Go to [dirbs.pta.gov.pk](https://dirbs.pta.gov.pk)
  2. Navigate to SIM verification: Look for “SIM Information System” or “Check SIM Registration” in the menu
  3. Enter your CNIC: Input your 13-digit CNIC number in the provided field
  4. Complete verification: You may need to verify via OTP sent to a registered number
  5. View results: The portal displays all SIMs linked to your CNIC with additional details

Advantages Over SMS

  • Detailed history: Shows registration dates and activation status
  • Download option: You can save or print the report for records
  • Complaint filing: Direct link to report unauthorized SIMs
  • Device verification: Same portal lets you check IMEI registration status

Portal Limitations

  • Requires internet access and a web browser
  • Occasional downtime during maintenance windows
  • May require OTP verification, which needs access to a registered number

Method 3: USSD Code Check

Each mobile operator also provides USSD codes for quick SIM verification directly from your phone.

Operator-Specific Codes

OperatorUSSD CodeWhat It Shows
Jazz/Warid*446#SIMs on your CNIC via Jazz network
Telenor*336#SIMs on your CNIC via Telenor network
Zong*310#SIMs on your CNIC via Zong network
Ufone*336#SIMs on your CNIC via Ufone network

How to Use

  1. Open your phone’s dialer
  2. Enter the USSD code for your operator
  3. Press the call button
  4. Follow on-screen prompts (usually requires entering CNIC)
  5. View results on screen

When to Use USSD vs. SMS to 668

  • USSD codes: Best for checking a single operator quickly
  • SMS to 668: Best for a complete cross-network overview in one query

How to De-Register Unauthorized SIMs?

You got CNIC information. Finding SIMs registered against your CNIC that you didn’t authorize? This is more common than you’d think—fraudulent registrations happen through identity theft, corrupt retailer practices, or data breaches. Here’s how to remove them.

Option 1: Online Complaint via PTA

  1. Visit PTA’s complaint portal: [complaint.pta.gov.pk](https://complaint.pta.gov.pk)
  2. Select complaint type: Choose “Unregistered/Illegal SIM” or “SIM Registration Fraud”
  3. Provide details:
    • Your CNIC number
    • The unauthorized phone number(s)
    • The operator(s) involved
    • Brief description of the issue
  4. Upload supporting documents:
    • Copy of your CNIC (front and back)
    • Screenshot of your 668 SMS showing the unauthorized SIM
  5. Submit and note your complaint ID
  6. Track progress: Use the complaint ID to check status online

Expected timeline: PTA typically responds within 7-14 working days. The unauthorized SIM will be blocked and deregistered.

Option 2: Visit Operator Franchise

For faster resolution, visit the franchise of the operator whose SIM was fraudulently registered.

Required documents:

  • Original CNIC (mandatory)
  • Photocopy of CNIC
  • Written application requesting de-registration
  • Screenshot of 668 SMS as evidence

Process:

  1. Visit any franchise or service center of the relevant operator
  2. Submit your documents to the customer service representative
  3. Fill out the SIM cancellation/dispute form
  4. Get an acknowledgment receipt with a reference number
  5. Follow up after 3-5 working days if not resolved

Option 3: FIA Cyber Crime Wing

If you suspect the unauthorized SIM was used for criminal activity, or if the above methods don’t work, escalate to FIA.

Contact FIA Cyber Crime:

  • Helpline: 9911
  • Website: [complaint.fia.gov.pk](https://complaint.fia.gov.pk)
  • Email: 

This route is appropriate when:

  • The SIM was used for fraud, harassment, or threats
  • You’re receiving legal notices for crimes you didn’t commit
  • Operators are unresponsive to your complaints
  • Multiple unauthorized SIMs suggest organized identity theft

NADRA’s Role in SIM Verification

While PTA handles SIM registration, NADRA (National Database and Registration Authority) manages the underlying identity infrastructure. Understanding this NADRA Sim owner details relationship helps when troubleshooting issues.

What NADRA Controls

  • CNIC database: The authoritative source for citizen identity data
  • Biometric records: Fingerprint data used during SIM registration
  • Identity verification API: The system telecom operators query during registration

When to Contact NADRA

Contact NADRA instead of (or in addition to) PTA if:

  • Your CNIC shows as blocked or expired during SIM registration attempts
  • Biometric verification repeatedly fails even with valid fingerprints
  • You suspect your CNIC data has been compromised beyond just SIM fraud
  • You need to update personal information (address, photo) that affects verification

NADRA Contact Options

  • NADRA helpline: 051-111-786-100
  • Pak-Identity portal: [id.nadra.gov.pk](https://id.nadra.gov.pk)
  • Visit NADRA office: For biometric re-enrollment or CNIC reissuance

CNIC Status Check

Before troubleshooting SIM issues, verify your CNIC is active:

  1. Send SMS with CNIC number to 8300
  2. Receive status confirmation (active, expired, blocked)
  3. If expired or blocked, resolve with NADRA first before addressing SIM issues

Legal Framework: PTA Regulations You Should Know

Common Issues and Troubleshooting

“668 Service Not Responding”

Possible causes:

  • Network congestion
  • System maintenance (usually overnight)
  • Incorrect CNIC format

Solutions:

  • Try again after 30 minutes
  • Ensure CNIC is 13 digits without dashes or spaces
  • Try from a different network’s SIM
  • Use the online portal as alternative

“CNIC Shows Zero SIMs But I Have Active Numbers”

Possible causes:

  • Recent SIM purchase not yet synced to central database
  • SIM registered under old/expired CNIC number
  • Corporate or family-registered SIM (under different CNIC)

Solutions:

  • Wait 24-48 hours for new registrations to sync
  • Check if your CNIC was recently renewed (old number may still be in system)
  • Contact operator to verify which CNIC the SIM is registered under

“Cannot De-Register SIM—Operator Says It’s Active”

Possible causes:

  • Outstanding balance or contract on the number
  • Number under investigation by authorities
  • Procedural delays at operator level

Solutions:

  • Request written explanation from operator
  • Escalate to PTA complaint portal with operator’s response
  • If legal hold exists, FIA can provide clearance letter

“Biometric Verification Fails Repeatedly”

Possible causes:

  • Worn fingerprints (manual labor, age-related)
  • Dirty or damaged scanner
  • Database mismatch with NADRA records

Solutions:

  • Clean and dry fingers before scanning
  • Try different finger (all 10 should be registered)
  • Request scanner cleaning or try different retailer
  • Visit NADRA for biometric re-enrollment if persistent

“Someone Else Registered a SIM Using My Fingerprint”

This is rare but serious—it indicates either:

  • Collusion by a retailer who had your biometric data
  • Sophisticated fraud using copied biometrics

Actions:

  1. File FIA complaint immediately (this is a criminal matter)
  2. File PTA complaint for SIM blocking
  3. Request NADRA biometric audit
  4. Consider civil lawsuit against retailer if identified

Protecting Yourself from SIM Fraud

Prevention is easier than resolution. Follow these practices:

Regular Monitoring

  • Check SIMs monthly: Send SMS to 668 on the 1st of each month
  • Set calendar reminder: Make it a routine habit
  • Review immediately: If you see unfamiliar numbers, act fast

Safe Registration Practices

  • Watch the biometric scan: Ensure retailer scans only once per SIM you’re purchasing
  • Get receipt: Always collect registration receipt showing your CNIC and number
  • Avoid unlicensed sellers: Purchase only from official franchises or authorized retailers
  • Don’t share CNIC copies unnecessarily: Each copy increases exposure risk

Secure Your CNIC

  • Report lost CNIC immediately: Call NADRA helpline to flag it
  • Don’t photograph both sides together: Makes identity theft easier
  • Shred old documents: Destroy papers containing CNIC numbers

Monitor for Fraud Indicators

Be alert if you:

  • Receive OTPs for accounts you didn’t create
  • Get calls/texts meant for someone else
  • Notice unfamiliar charges in mobile wallet
  • Receive legal notices for unknown numbers

Frequently Asked Questions

Everything you need to know about checking SIM owner details in Pakistan

How can I check SIM owner details by mobile number in Pakistan?

You cannot directly check another person’s SIM owner details using just their mobile number—this information is protected under privacy laws. However, you can check all SIMs registered against your own CNIC by sending your 13-digit CNIC number to 668. For investigating unknown numbers, you must file a complaint with FIA Cyber Crime (helpline 9911) who can access this information for legitimate legal purposes.

Is the 668 SMS service free?

The 668 service is not completely free—standard SMS charges apply, typically Rs. 2-3 depending on your mobile operator. However, there’s no additional government fee for the verification itself. The PTA online portal at dirbs.pta.gov.pk offers the same information without SMS charges if you have internet access.

How many SIMs can be registered on one CNIC in Pakistan?

The standard limit is 5 SIMs per mobile network operator, meaning you could theoretically have up to 25 total SIMs (5 each on Jazz, Telenor, Zong, Ufone, and SCOM). However, operators can set lower limits, and PTA monitors for suspicious patterns. Corporate accounts have different limits based on business documentation.

What should I do if I find unauthorized SIMs on my CNIC?

Take these steps immediately: First, document the issue by screenshotting your 668 response. Then file a complaint on PTA’s portal (complaint.pta.gov.pk) with your CNIC copy and evidence. You can also visit the relevant operator’s franchise with your original CNIC to request de-registration. If you suspect criminal use, report to FIA Cyber Crime at 9911. The unauthorized SIM should be blocked within 7-14 days.

Can I check SIM owner details using CNIC number online?

Yes, but only for SIMs registered against your own CNIC. Visit PTA’s DIRBS portal at dirbs.pta.gov.pk, enter your CNIC number, complete OTP verification, and view all registered SIMs. You cannot use this system to look up SIMs registered under someone else’s CNIC—that would require legal authority.

Why does my 668 check show zero SIMs when I have active numbers?

This usually happens for three reasons: your SIM was recently activated and hasn’t synced to the central database yet (wait 24-48 hours), your SIM is registered under a different CNIC (such as a family member’s or old CNIC number), or there’s a technical glitch. Contact your operator’s helpline to verify which CNIC your specific number is registered under.

How long does it take to de-register an unauthorized SIM?

Through PTA’s complaint portal, expect resolution within 7-14 working days. Visiting an operator franchise directly can be faster—typically 3-5 working days. FIA complaints take longer (2-4 weeks) but are necessary if criminal activity is involved. Keep your complaint reference number and follow up if you don’t see action within the expected timeframe.

Can someone register a SIM on my CNIC without my fingerprint?

Technically no—biometric verification has been mandatory since 2014, requiring a live fingerprint scan. However, fraud still occurs through retailer collusion (using stored biometrics from previous transactions), system glitches, or sophisticated fingerprint spoofing. If you find unauthorized SIMs despite biometric requirements, report to both PTA and FIA, as this indicates criminal activity.

Final Thoughts

Pakistan’s SIM registration system, while not perfect, gives citizens significant control over their telecommunications identity. The key is using it proactively—don’t wait until you’re a victim of fraud to check what’s registered under your name.

Make the 668 check a monthly habit. It takes 30 seconds and could save you from serious legal and financial complications down the road. If you find unauthorized SIMs, act immediately—the longer they remain active, the more potential damage they can cause.

For ongoing protection, combine regular monitoring with safe registration practices and immediate reporting of any suspicious activity. The system works, but only if you use it.
