SIM information in Pakistan refers to the complete set of identity and registration records tied to every active mobile SIM card operating on Pakistani networks. This data is officially maintained by the Pakistan Telecommunication Authority (PTA) in coordination with NADRA and all licensed telecom operators: Jazz, Zong, Telenor, Ufone, SCO, and Onic.

When you activate any SIM card in Pakistan, your biometric and identity data is captured at the point of sale, verified through the National Database and Registration Authority (NADRA), and stored in Pakistan’s centralized SIM Information System. This system serves as the authoritative database for all mobile subscriber records in the country. Whether you want to verify your own registered SIMs, check what information is stored against your CNIC, look up a number’s network details, or understand how Pakistan’s SIM database works, this guide explains the concepts, official methods, and step-by-step processes.

What Is SIM Information in Pakistan?

SIM information is the official identity profile linked to a mobile SIM card in Pakistan’s telecom ecosystem. Every SIM sold and activated in Pakistan is legally required to be registered with a valid CNIC through biometric verification. This requirement was made fully mandatory after the nationwide re-verification drive in 2015. A typical SIM information record for any mobile number in Pakistan contains the following data fields:

Data field	Description
Registered owner’s full name	As per NADRA CNIC records
CNIC number	13‑digit national identity number
Home address	Address on file with NADRA
Network operator	Jazz, Zong, Telenor, Ufone, SCO, Onic
Number prefix / series	For example, 030x, 031x, 032x, 033x, 034x, 037x
SIM activation date	Date of first biometric registration
Biometric verification status	Verified / Unverified / Pending
SIM status	Active / Blocked / Suspended / Ported / Not registered
Total SIMs on CNIC	Count per operator across all networks
CNIC‑to‑SIM link status	Whether ownership is confirmed with NADRA
This data exists in a distributed but synchronized system. Each telecom operator maintains its own subscriber database, which is synced in near real time with PTA’s centralized SIM Information System.

What Is Pakistan’s SIM Information System?

Pakistan’s SIM Information System (SIS) is the centralized digital registry operated by PTA that stores and manages the SIM registration data of all mobile subscribers in the country. It was introduced to tackle telecom fraud, SIM-based crimes, and identity misuse. The system is built on a three‑layer architecture:

• Layer 1 – NADRA verification engine: Every SIM registration is biometrically cross‑checked against NADRA’s national identity database. If the fingerprints or CNIC data do not match, the SIM cannot be activated.
• Layer 2 – Operator subscriber management systems: Jazz, Zong, Telenor, Ufone, SCO, and Onic maintain their own subscriber databases that capture SIM activity, porting history, package subscriptions, and registration logs.
• Layer 3 – PTA central repository: PTA aggregates data from all operators into a single national database, accessible to citizens via the simowner.com.pk portal and the 668 SMS service.
  The system currently holds records for hundreds of millions of mobile connections in Pakistan, making it one of the largest biometrically verified telecom databases in the world.

Why SIM Information Matters in Pakistan (2026)

Pakistan’s mobile ecosystem is deeply integrated with banking, identity verification, and digital services. Your SIM is no longer just a phone number; it is a primary digital identity anchor. Key reasons to understand and monitor your SIM information include:

1. Bank account access: Almost every major bank uses your registered mobile number for OTPs and alerts. An unauthorized SIM on your CNIC can give fraudsters an entry point to your financial accounts.
2. SIM swap fraud: A fraudster can visit a network franchise, pretend to be you, and get a replacement SIM on your number, locking you out and receiving your OTPs.
3. Identity misuse: Unknown persons may register SIMs under your CNIC if biometric records were leaked or misused. Regular checks help detect this early.
4. Legal liability: If a SIM registered under your CNIC is used in any crime, you can be called for investigation. Claiming you “did not know” does not remove your responsibility to secure your identity.
5. PTA compliance limits: PTA currently applies a maximum of 5 voice SIMs and 3 data SIMs per CNIC across all networks combined. Exceeding this limit can trigger blocking of some SIMs. Knowing your current count avoids accidental disconnections.

How to Check SIM Information in Pakistan – Official Methods

There are four officially supported methods to access your SIM information in Pakistan. Each has specific use cases, advantages, and limitations.

Method 1: PTA Online Portal

The PTA SIM Information System portal at simowner.com.pk is the most comprehensive online way to check all SIMs registered under your CNIC across all networks.
Steps

1. Open your browser and go to simowner.com.pk.
2. On the homepage, find the CNIC input field.
3. Enter your 13‑digit CNIC number without dashes (for example, 3520212345678).
4. For foreign nationals, select “Foreign ID” and enter your passport or NICOP number.
5. Complete the CAPTCHA verification.
6. Click “Submit”.
   What you see

• Number of active SIMs per operator (for example, Jazz: 2, Zong: 1).
• Total SIM count across all networks.
• Sometimes status labels against each operator’s SIM entries.
  Individual phone numbers are partially masked for privacy.
  Limitation: The portal shows counts per operator, not full numbers. For full number-level details, you must visit the relevant operator franchise with your CNIC.

Method 2: SMS to 668 (Fastest – No Internet Required)

The 668 SMS service is operated by PTA and works from any Pakistani mobile network. It is ideal for quick checks when you do not have internet access.
Steps

1. Open your phone’s SMS app.
2. Type your 13‑digit CNIC number without dashes or spaces.
3. Send the SMS to 668.
4. Within 30–60 seconds, you will receive an automated reply.
   Sample response (format)

SIMs registered on CNIC XXXXXXXXXXXXX:
Jazz: 2
Zong: 1
Telenor: 0
Ufone: 1
Total: 4 SIMs
Standard SMS charges apply, but many packages effectively make this very low cost. If you do not receive a response within a few minutes, double‑check that your CNIC was typed correctly and try again. If it still fails, use the web portal instead.

Method 3: Individual Operator USSD and SMS Codes (Network‑Specific)

Each telecom operator provides its own USSD and SMS methods to check SIM registration and basic details for its own network. These are useful when you want to verify one specific SIM. Typical options (these may change over time, always confirm with the operator):

• Dial a USSD menu such as *321#, *310#, *888#, or *336# depending on the operator.
• Send an SMS like MNP to 667 to see which network a number currently belongs to and basic details.
  These checks usually show information like registered owner name (possibly masked), CNIC (partially masked), activation date, and sometimes package status.

Method 4: Operator Franchise Visit (Most Complete – Offline)

For complete SIM information, including full numbers, full CNIC, and detailed registration history, a physical visit to the operator’s franchise or customer service center is required. Use this method when you need to:

• Dispute incorrect SIM information.
• Block or disown unauthorized SIMs.
• Request SIM ownership transfer.
• Resolve unverified, blocked, or suspicious SIM statuses.
  What to bring
• Original CNIC (mandatory).
• In some cases, your SIM card and a working phone.
  Biometric verification will be performed on‑site before sensitive changes such as disowning or ownership transfer.

Understanding Your SIM Information Results

After checking your SIM information, you might see different status labels. Knowing what they mean helps you react correctly.

Status	Meaning	Recommended action
Active	SIM is properly registered, verified, and in normal use	No action needed; check periodically
Blocked	SIM has been deactivated by PTA or operator	Contact operator to learn the reason and resolve
Unverified	SIM exists but biometric verification is incomplete	Visit franchise with CNIC to complete verification
Suspended	Temporary hold due to limits, misuse, or policy action	Contact operator or PTA to clarify
Ported	Number moved to another operator (MNP)	Contact the new operator if any issue arises
Not registered	Number not found in official systems	Avoid using; could be illegal or improperly issued

SIM Database vs SIM Information System – Key Differences

Many users confuse “SIM database” with the official “SIM Information System”. They are related concepts but not the same.
PTA SIM Information System (simowner.com.pk / 668)

• Official platform operated by PTA.
• Shows SIMs registered on your own CNIC only.
• Data is authoritative and regulated.
• Access is restricted to protect citizen privacy.
  Third‑party “SIM database” websites
• Run by private individuals or companies without PTA authorization.
• Data may be outdated, inaccurate, or obtained without consent.
• Often claim to show full personal details of any number.
• Using such sites can expose your CNIC and number to further misuse.
  The safe rule: for any SIM verification or security action, only use PTA’s official channels or your operator’s official channels.

How to Check SIM Information by Number

Many users want to identify an unknown caller or verify who owns a number that called them. There are strict privacy rules around this.
What you can check

• Which network a number belongs to by sending MNP to 667 from most networks.
• Whether a number is currently active or ported, using operator tools.
• Basic registration status of your own number, using operator USSD or account apps.
  What you cannot legally access as a normal user
• Full owner name of a number that is not yours.
• CNIC number or address of another subscriber.
• Detailed registration history of another person’s number.
  These restrictions are intentional privacy protections. Websites that claim to show full personal data of any phone number are almost certainly using unauthorized or leaked information.

SIM Information With CNIC – Reverse Lookup

The main legitimate public use case is CNIC → SIMs (reverse lookup by CNIC). This lets you see how many SIMs are registered under your identity so you can keep your CNIC clean and secure.
Step‑by‑step

1. Go to simowner.com.pk or send your CNIC to 668.
2. Note the count of SIMs per operator.
3. If every SIM is known and under your control, you are safe for now.
4. If you see any unknown SIM entries: identify which operator the unknown SIM belongs to, visit that operator’s franchise with your original CNIC, request disowning or blocking of that SIM through biometric verification, and keep the reference number.
5. After 48–72 hours, repeat the 668 or portal check to confirm removal.

Fresh SIM Data vs Outdated SIM Information – Why Recency Matters

SIM information in Pakistan changes regularly because of:

• Number porting (MNP) between networks.
• SIM ownership transfers.
• PTA verification and re-verification campaigns.
• Operator actions such as blocking for non‑payment and later reactivation.
• New number series launches by operators.
  Any static or downloaded “SIM database” can become outdated quickly. If you are relying on SIM data for security, legal, or business reasons, always perform a fresh check through official systems just before taking action.

SIM Information for All Pakistani Networks (2026)

Jazz SIM Information

Jazz (formerly Mobilink) is Pakistan’s largest operator, with major number prefixes in the 0300–0309 range. You can use 668 or simowner.com.pk to check Jazz SIMs on your CNIC, Jazz USSD menus and the Jazz World app for SIM and account details, and Jazz franchises for full ownership and registration services.

Zong SIM Information

Zong operates a leading 4G/5G network with prefixes 0310–0319, 0320–0329, and 0340–0349. You can use PTA methods for SIM counts, Zong’s self‑service USSD codes for number and bundle details, and Zong customer service centers for biometric verification and ownership issues.

Telenor SIM Information

Telenor Pakistan uses number ranges like 0330–0339, 0345–0348, and 0360–0369. You can use PTA methods to see SIMs on your CNIC, Telenor USSD codes and the My Telenor app for SIM status and packages, and Telenor franchises to resolve ownership or verification problems.

Ufone SIM Information

Ufone (a PTCL subsidiary) has strong presence with prefixes such as 0311 and 0333–0337. You can use simowner.com.pk or 668 to see how many Ufone SIMs are on your CNIC, Ufone USSD menus and the My Ufone app for SIM information, and Ufone service centers to block, disown, or transfer SIMs.

SCO SIM Information

The Special Communication Organization (SCO) operates in Azad Jammu & Kashmir and Gilgit‑Baltistan with prefixes like 0321–0325. PTA’s tools still show SCO SIM counts on your CNIC, while SCO franchises and helplines handle detailed SIM information and ownership changes.

Onic SIM Information (New 2024–)

Onic is a newer digital‑first operator using the 037x number series. SIM information checks still route through PTA’s tools: use simowner.com.pk and 668 for SIM counts and official Onic apps or contact points for line‑level details and support.

Legal Framework Governing SIM Information in Pakistan

SIM information is governed by telecom regulations and cybercrime laws that aim to ensure that every SIM is registered to a verified identity, prevent anonymous or illegally obtained SIMs, and protect subscriber privacy and data. In practice, this means you must use your own valid CNIC or an accepted foreign ID to register SIMs, operators must capture and verify your biometric data, and unauthorized access to other people’s SIM data is a punishable offence.
Your rights as a subscriber include:

• The right to check all SIMs registered on your CNIC via official channels.
• The right to block or disown any SIM registered on your CNIC without your consent.
• The right to file complaints with PTA regarding SIM misuse or registration errors.
• The right to request full subscriber data for your own numbers directly from the operator.

Frequently Asked Questions – SIM Information Pakistan

Q1. What is SIM information in Pakistan?
SIM information is the official identity and registration data linked to a mobile SIM card in Pakistan’s PTA–NADRA system. It includes the registered owner’s name, CNIC number, address, network operator, activation date, and biometric verification status.
Q2. How can I check all SIM information on my CNIC for free or low cost?
You can send your 13‑digit CNIC number (without dashes) as an SMS to 668 from any Pakistani network to receive a reply listing how many SIMs are registered against your CNIC with each operator. You can also use the simowner.com.pk portal for a more detailed breakdown.
Q3. What does the SIM Information System show exactly?
The SIM Information System shows the number of active SIMs registered per telecom operator against your CNIC, plus a total count. For privacy reasons, it usually shows counts rather than full phone numbers.
Q4. Is it legal to check someone else’s SIM information in Pakistan?
No. You are allowed and encouraged to check SIMs registered on your own CNIC, but accessing another person’s SIM information without their consent is against privacy and cybercrime laws and can lead to penalties.
Q5. How many SIMs can be registered on one CNIC in Pakistan?
PTA currently allows up to 5 voice SIMs and 3 data or MBB SIMs per CNIC, across all networks combined. Attempting to exceed this limit can lead to blocking of some connections.
Q6. What should I do if an unknown SIM is registered on my CNIC?
Visit the franchise of the operator whose SIM appears as unknown on your CNIC, take your original CNIC, request biometric disowning or blocking of that SIM, and ask for a reference number. Then recheck through 668 after a few days to confirm removal.
Q7. How often should I check my SIM information?
It is wise to check every 3–6 months, and immediately if you lose your CNIC, suspect identity theft, or notice unusual calls, messages, or financial activity.
Q8. Why does my SIM show as “Unverified” in PTA or operator records?
This usually means your SIM was issued without fully completed biometric verification, or was purchased before strict biometric rules and never updated. You need to visit the operator’s franchise with your CNIC and complete biometric verification to avoid blocking.
Q9. Can I check SIM information without internet?
Yes. You can use the 668 SMS service from any network by sending your CNIC number without dashes. The reply will show how many SIMs are registered against your CNIC per operator.
Q10. What is the difference between SIM information and SIM owner details?
SIM information refers to the full technical and registration dataset for a SIM (status, activation, network, verification, and history). SIM owner details specifically refers to the identity data of the person who registered the SIM, such as name, CNIC, and address. SIM owner details are a subset of the broader SIM information.
Q11. Does checking SIM information put my data at risk?
Not when you use official channels like simowner.com.pk 668, and operator franchises. The real risk appears when you enter your CNIC or phone number on unverified third‑party sites that claim to offer full SIM or CNIC databases.
Q12. What is the PTA helpline for SIM information problems?
PTA operates a consumer support helpline and an online complaint portal where you can report issues like unauthorized SIMs on your CNIC, blocking problems, and other telecom complaints. Check the official PTA site or your operator’s website for current contact numbers and timings.
