If you’ve ever wondered how many SIM cards are registered under your CNIC (Computerized National Identity Card), you’re not alone. Many people in Pakistan have unknowingly had SIMs issued in their name without their consent. This can lead to serious privacy and security problems, including misuse of your identity.
Thankfully, you can now check all SIM numbers on your ID card online through simple tools and platforms that are fast, free, and secure. One of the most trusted tools for this purpose is TrueCallID, Pakistan’s leading Caller ID app that helps you identify unknown numbers and verify who’s calling you.
In this complete guide, you’ll learn everything — from checking all SIMs registered on your ID card to verifying caller details and staying safe from fraud.
Introduction to SIM Verification in Pakistan
In Pakistan, every SIM card is registered under a valid CNIC number issued by NADRA (National Database and Registration Authority). This process is controlled by PTA (Pakistan Telecommunication Authority), which monitors SIM ownership to ensure user safety and prevent illegal activities.
However, due to the rise in identity misuse and unauthorized SIM registration, it’s become important for every Pakistani citizen to check which SIM numbers are active under their CNIC.
Before online systems existed, people had to visit franchise centers to find this information. But now, with platforms like TrueCallID, this process takes only a few seconds.
You can easily check:
How many SIMs are registered on your ID card
Which mobile networks they belong to
Who is using your registered numbers
Whether there’s any suspicious or unknown SIM linked to your name
Why You Should Check SIMs Registered on Your ID Card
Verifying your SIM ownership is more than just a good habit — it’s essential for your security. Here’s why:
Prevent Identity Theft
If someone gets unauthorized access to your CNIC number, they could register a SIM under your name. That SIM could then be used for illegal or unethical activities, and you could be held responsible. Checking regularly ensures your name isn’t being misused.
Control Over Your SIMs
Sometimes, people forget about old SIMs they once owned. Checking your CNIC helps you know exactly how many numbers are still active and which ones you might want to block.
Stay Safe from Scammers
Scammers often use fake or unregistered numbers to trick users. With TrueCallID, you can instantly see the name and photo of the caller, helping you recognize who’s calling before you even answer.
Comply with PTA Rules
PTA allows a maximum of five SIM cards per person per network. If you unknowingly have more, you could face issues when trying to register new ones. Checking helps you stay within legal limits.
Peace of Mind
Knowing your SIMs are all registered correctly gives you peace of mind. You can be confident that no one is misusing your CNIC.
How SIM Registration Works in Pakistan
Understanding how SIM registration works helps you see why checking your SIM status is so important.
When you buy a new SIM card in Pakistan:
You must show your original CNIC at the mobile network’s franchise or retailer.
Your fingerprint is verified through Biometric Verification System (BVS).
The SIM is then registered under your CNIC, linking your name, photo, and ID details with that specific number.
The networks that follow this process include:
Jazz
Zong
Ufone
Telenor
SCOM
Once registered, your details are stored in PTA’s central database. If you later buy more SIMs, they all get linked to your CNIC.
The problem starts when:
Retailers use your CNIC copy without your permission
You lose your ID card, and someone misuses it
Your thumbprint data is stolen or misused
That’s why regular checks are necessary.
How to Check All SIM Numbers on ID Card Online
Now let’s look at the most reliable ways to check all SIM numbers linked to your CNIC.
Using TrueCallID
TrueCallID is the most convenient and powerful way to check all SIMs registered on your CNIC. It’s more than just a caller ID app — it helps you verify who owns any number in Pakistan and protects you from fake or spam callers.
Step-by-Step Process
Visit the official TrueCallID platform.
Enter your CNIC number (without dashes).
Click “Check SIM Numbers.”
Within seconds, you’ll see all active SIMs linked to your CNIC.
You’ll also be able to see:
The network name (Jazz, Zong, Ufone, Telenor, or SCOM)
The status (active or inactive)
The registration date
The SIM ownership details
Unlike other tools, TrueCallID also lets you identify unknown numbers calling or texting you. It matches the caller’s number with its verified database to show their name and photo.
Through PTA SIM Information System
PTA also provides an official way to check SIMs via their online system.
Steps
Go to the PTA SIM Information website.
Enter your CNIC number.
Complete the captcha verification.
Click “Submit.”
You’ll get a list of all active SIMs registered under your CNIC, sorted by mobile network.
While this method is reliable, it doesn’t show caller names or personal details — it only displays how many SIMs you have. That’s why many users prefer TrueCallID for a more complete experience.
By SMS
If you don’t have internet access, you can use the SMS method.
Steps
Open the SMS app on your phone.
Type your CNIC number (without dashes).
Send it to 668.
Within seconds, you’ll receive a reply listing all active SIMs under your CNIC. Each line will show the mobile network name and total count of SIMs.
This method is quick but doesn’t show the actual phone numbers. For that, TrueCallID remains the best choice.
