Pakistan’s entire SIM registration and verification system is built on CNIC and NADRA. Understanding how your identity card and NADRA’s biometric database work is essential if you want full control over the SIMs registered on your name.

In Pakistan, every SIM card must be linked to a CNIC stored in NADRA’s national database. Mobile operators verify your fingerprints and CNIC details against NADRA through the Biometric Verification System (BVS), making CNIC and NADRA the core of legal SIM ownership and verification.

SIM Owner Details Pakistan

What Is CNIC and What Information Does It Contain?

The Computerized National Identity Card (CNIC) is Pakistan’s primary identity document, issued by NADRA, and used for everything from SIM registration to banking and voting. It combines a unique 13‑digit number with detailed biographical and biometric data.

40‑word extractive answer:
CNIC is Pakistan’s 13‑digit national identity card containing your name, photo, address, date of birth, family details, and biometric data such as fingerprints and facial image. NADRA issues and manages CNICs, which are mandatory for legal SIM registration and verification.

CNIC number format (13 digits)

A typical CNIC looks like 12345‑1234567‑1. Internally, those digits encode:

• Region/area code (first 5 digits) – identifies your registration area.
• Serial number (next 7 digits) – unique within that area.
• Check digit (last digit) – used for validation and error checking.

For online and SMS systems such as SIM verification, you always enter 13 digits without dashes (e.g., 1234512345671).

Personal and biometric data in CNIC

NADRA’s back‑end record for your CNIC typically includes:

• Biographical data
  • Full name
  • Father’s or spouse’s name
  • Date of birth
  • Permanent and present addresses
  • Gender and marital status
• Biometric data
  • Ten fingerprints (both hands)
  • Facial photograph
  • In some cases, iris scans for high‑security applications

This biometric information is what telecom operators rely on when they scan your fingerprints for SIM verification. The scanned prints are matched against NADRA’s database to confirm that you are the legitimate CNIC holder.

Types of identity cards

• CNIC – for Pakistani citizens residing in Pakistan.
• NICOP – National Identity Card for Overseas Pakistanis.
• POC – Pakistan Origin Card for eligible foreign nationals of Pakistani origin.

Each card type can be used for SIM registration, but processes and documentation can differ slightly for overseas Pakistanis and POC holders.

What Is NADRA and How Does It Connect to SIM Registration?

NADRA (National Database & Registration Authority) is the institution that issues CNICs and maintains Pakistan’s centralized citizen database. Telecom operators connect to NADRA’s systems to verify your identity before they can associate a SIM with your CNIC.

NADRA is Pakistan’s National Database & Registration Authority, responsible for issuing CNICs and maintaining a large biometric database. Mobile operators use secure connections to NADRA’s systems to confirm fingerprints and CNIC details before registering or verifying any SIM on your name.

NADRA’s core responsibilities

• Issuing and renewing CNICs, NICOPs, and POCs.
• Maintaining a national citizen database with personal and biometric data.
• Supporting identity verification for:
  • Telecom (SIM registration)
  • Banking (account opening, biometric KYC)
  • Government services (benefits, passports, voting)

Through this centralized infrastructure, NADRA acts as the single source of truth for a person’s identity in Pakistan.

How NADRA integrates with mobile operators

When you buy or verify a SIM:

1. The operator’s Biometric Verification System (BVS) captures your fingerprints (and increasingly your face).
2. Those biometric samples are encrypted and sent to NADRA over a secure channel.
3. NADRA compares the samples with your stored CNIC biometric data.
4. The result (match/no match) is returned to the operator in real time.
5. If it matches, the SIM is registered or verified against your CNIC.

This means your SIM is not just linked to a number on a form—it is linked to your real identity in the NADRA database.

How Many SIMs Can Be Registered on One CNIC in Pakistan?

Pakistan limits the number of SIMs that can be associated with a single CNIC to reduce fraud and misuse. These limits are enforced collectively across all networks, not per operator separately.

A single CNIC in Pakistan can have up to 5 voice SIMs and 3 data‑only SIMs registered at any one time, giving a total limit of 8 connections. When you reach this limit, new SIM registrations may be rejected or older unused SIMs must be disowned.

Current SIM limits per CNIC

Regulatory policy allows:

• 5 voice SIMs (for regular calling and data).
• 3 data‑only SIMs (e.g., tablets, Wi‑Fi devices, M2M), depending on the latest PTA implementation.

Combined, you can effectively maintain up to 8 active registrations tied to your CNIC.

These limits are enforced across all operators collectively. For example:

• 2 Jazz voice SIMs
• 1 Telenor voice SIM
• 1 Zong voice SIM
• 1 Ufone voice SIM
• 3 data SIMs on any combination of networks

If you try to register a 6th voice SIM, the system will typically block the request or require you to disown an existing SIM first.

Why SIM limits exist

• To make it harder for criminals to operate large numbers of anonymous SIMs.
• To stop “SIM farming” by retailers or agents.
• To limit abuse of other people’s CNICs for bulk registrations.
• To improve traceability and security for law enforcement.

What happens when you exceed the limit?

• New SIM purchases may be declined at the franchise.
• Operators and PTA may block or deactivate some older, unused SIMs associated with your CNIC.
• You may be requested to visit a franchise for re‑verification or cleanup of your registrations.

Because of these limits, it is good practice to periodically check how many SIMs are on your CNIC and disown any you no longer use.

How Can You Check All SIM Cards Registered on Your CNIC?

To manage SIMs effectively, you need a complete view of what is already registered on your CNIC. PTA provides two main methods—a website and an SMS short code—to give you this overview.

You can see all SIMs registered on your CNIC by either visiting cnic.sims.pk and entering your 13‑digit CNIC or sending your CNIC number via SMS to 668. Both methods return operator‑wise counts of active SIMs linked to your identity.

Method 1 – PTA’s SIM Information website

• Visit cnic.sims.pk in a web browser.
• Enter your 13‑digit CNIC without dashes.
• Complete the CAPTCHA and submit.
• View a table showing how many SIMs each operator has registered on your CNIC.

This method is free and works from anywhere, including outside Pakistan, as long as you have internet access.

Method 2 – SMS to 668

• From any Pakistani SIM, type your 13‑digit CNIC (no dashes).
• Send it as an SMS to 668.
• Receive a reply listing total SIMs per operator tied to your CNIC.

This method is paid (small fee per SMS) but works even with a basic phone and no data.

Interpreting the results

Typically, you’ll see something like:

• Jazz: 2
• Zong: 1
• Telenor: 0
• Ufone: 1

This tells you how many SIMs each network has registered against your CNIC. It doesn’t list individual numbers, but you can infer them from the SIMs you actively use.

If these counts look higher than expected, it may mean:

• You forgot older SIMs you don’t use anymore.
• A retailer registered extra SIMs on your CNIC without permission.
• Your CNIC was misused in the past.

In such cases, your next steps are:

• Visit the concerned operator’s franchise to identify and disown unwanted SIMs.
• Use PTA’s complaint system if operators don’t resolve the issue.

What Is Biometric Verification and How Does It Link CNIC to SIM?

Biometric verification is the process that ties your SIM card to your actual physical identity by comparing your fingerprint or facial data with what NADRA has stored under your CNIC.

40‑word extractive answer:
Biometric verification uses a fingerprint scanner or facial recognition at operator franchises to match your live biometrics against NADRA’s CNIC records. When the match is successful, the SIM is registered or verified on your CNIC, creating a strong, legally valid link between phone number and identity.

How biometric verification works in practice

1. Enrollment at a franchise or customer service center
   • You present your original CNIC.
   • Staff enter your CNIC number in the Biometric Verification System.
2. Biometric capture
   • You place your thumbs or multiple fingers on the scanner.
   • In newer setups, a camera may also capture your face for facial recognition.
3. Real‑time NADRA match
   • The BVS sends an encrypted biometric sample to NADRA’s servers.
   • NADRA compares it to the stored biometric data for the CNIC.
   • NADRA returns a yes/no match result.
4. Operator action based on result
   • If matched, the SIM is activated or updated as verified on your CNIC.
   • If not matched, the transaction is declined, and you may be asked to visit NADRA to update your records.

When biometric verification is required

• New SIM activation for any network.
• Ownership transfer from one person to another.
• Duplicate SIM issuance (e.g., lost, damaged SIM).
• Re‑verification campaigns ordered by PTA.
• Certain MNP (port‑in) situations where operator needs fresh verification.

What if your fingerprints don’t match?

Common reasons:

• Faded or damaged fingerprints (manual labor, aging).
• Old biometric data in NADRA that no longer matches your fingers.
• Minor errors during initial capture.

Possible solutions:

• Trying different fingers.
• Using alternative biometric methods where available (such as facial recognition).
• Visiting a NADRA registration center to update your biometrics.

What Is the Impact of CNIC Expiry on Your SIMs?

An expired CNIC doesn’t just affect your ability to travel or open bank accounts; it can also impact your SIM cards. Regulatory drives have targeted SIMs registered on expired or invalid CNICs, leading to blocking or deactivation.

40‑word extractive answer:
If your CNIC expires and you don’t renew it, SIMs registered on that number risk being blocked during PTA and NADRA clean‑up drives. Once you renew your CNIC, you may need to re‑verify your SIMs biometrically at operator franchises to restore full service.

CNIC validity periods

• Standard CNICs have a fixed validity period (often 5 or 10 years depending on age and issuance rules).
• After expiry, they are considered invalid for official purposes until renewed.

How expired CNICs affect SIMs

Regulatory clean‑ups have:

• Identified SIMs registered on expired CNICs.
• Blocked or suspended those SIMs until the CNIC is renewed.
• Forced users to update and re‑verify identity.

If your CNIC is nearing expiry:

• Renew it early at NADRA.
• Once you receive the new CNIC, keep it with you for any future SIM‑related verification.

If your SIM was blocked due to CNIC expiry:

1. Renew CNIC at NADRA.
2. Visit the operator’s franchise with the new CNIC.
3. Perform biometric verification again if required.
4. Request reactivation.

How Does NADRA’s Pak‑ID App Support Digital Identity and SIM‑Related Use Cases?

The Pak‑ID mobile app is NADRA’s digital identity platform, allowing citizens to manage ID services online. While you cannot yet complete SIM registration entirely inside the app, it can support identity verification and documentation in multiple ways.

40‑word extractive answer:
NADRA’s Pak‑ID app lets Pakistani citizens and overseas Pakistanis apply for, track, and manage CNIC and NICOP services digitally. Although SIM registration still occurs through operators, Pak‑ID provides digital proof of identity and can streamline documentation for SIM‑related processes and verifications.

Key Pak‑ID features

• Apply for new CNIC/NICOP, renewal, or modification.
• Upload documents and pay fees online.
• Track application status.
• View digital copies of identity documents.
• Manage profiles for multiple family members (where applicable).

How Pak‑ID indirectly helps with SIM matters

• You can ensure your CNIC is valid and track renewal without visiting an office unnecessarily.
• Digital records from Pak‑ID confirm your identity details when dealing with operators.
• In future, deeper integration could allow more seamless SIM registration using digital identity.

Although operators still need in‑person biometric verification, having up‑to‑date CNIC data through Pak‑ID reduces issues during SIM verification.

What Is the Difference Between CNIC, NICOP, and POC for SIM Registration?

Different categories of Pakistanis hold different identity cards, but all three—CNIC, NICOP, and POC—can be involved in SIM registration with slightly different procedures.

CNIC is for residents inside Pakistan, NICOP is for overseas Pakistanis, and POC is for eligible foreign nationals of Pakistani origin. All can be used to register SIMs, but NICOP and POC holders may follow special procedures and documentation requirements when buying or verifying numbers.

CNIC (for residents inside Pakistan)

• Standard card for citizens living in Pakistan.
• Used for local SIM purchases and all everyday KYC processes.
• Requires in‑country biometric verification via BVS.

NICOP (for overseas Pakistanis)

• Designed for Pakistanis living abroad.
• Enables opening of bank accounts, property dealings, and SIM registration in Pakistan when visiting.
• When overseas Pakistanis are physically in Pakistan, they can use NICOP plus biometric verification at franchises to register SIMs.

Some special arrangements may exist for temporarily registering SIMs for overseas Pakistanis and visitors, but these still rely on NADRA and PTA rules.

POC (Pakistan Origin Card)

• For foreign nationals with Pakistani origin who meet certain eligibility criteria.
• Provides some rights for travel and stay in Pakistan.
• Can be used in conjunction with passport for SIM registration, subject to current operator and PTA policies.

For all three documents, the critical factor is that identity must be verifiable through NADRA or other approved mechanisms. Biometric verification still applies for SIM activation wherever feasible.

FAQs 

Can I register a SIM in Pakistan without CNIC?
No. For Pakistani citizens, a valid CNIC (or NICOP/POC for specific cases) is mandatory for SIM registration. Operators must perform biometric verification against NADRA’s database before activating any new connection.

Is my biometric data safe with NADRA and telecom operators?
Your biometric data is stored and processed under secure government‑grade systems and transmitted in encrypted form between BVS terminals and NADRA. Operators typically store only what is required for verification logs, not the full raw biometric template.

How many SIMs should I actually keep on my CNIC?
Even though the limit is higher, it’s wise to keep only the SIMs you actively use. The more SIMs on your CNIC, the harder it is to monitor them and the higher your risk if any are misused.

What should I do if my CNIC information is wrong in the operator’s system?
If your name or CNIC details appear incorrectly in an operator’s records, visit their franchise with your CNIC for correction. In more complex cases, you may need to update data at NADRA first and then re‑verify with the operator.

Do I need to re‑verify my SIM after renewing my CNIC?
Often, operators and PTA run time‑bound campaigns where SIMs on renewed or reissued CNICs must be re‑verified. If you’ve renewed your CNIC, it’s good practice to visit a franchise and confirm your SIMs are still correctly linked.

Can overseas Pakistanis manage SIMs on their CNIC remotely?
Overseas Pakistanis can use PTA’s SIM Information website to see SIM counts on their CNIC and, in some cases, access online services to block or regularize extra SIMs. For complex issues, they may need to authorize someone locally or visit Pakistan.

What if my fingerprints never match at franchises?
If your fingerprints repeatedly fail (due to age, injuries, or manual labor), you should visit a NADRA center to update your biometric record. Where available, facial recognition‑based verification may also be offered as an alternative.

Conclusion

Every SIM you own in Pakistan ultimately depends on two pillars: your CNIC and NADRA’s identity database. CNIC defines who you are in official records, and NADRA’s biometric systems ensure that only the genuine cardholder can register or verify SIMs.
