If you’ve ever wondered exactly how many mobile numbers are sitting quietly under your CNIC, you’re not alone.

What Is the PTA SIM Information System?
At its core, the PTA SIM Information System is a public verification tool that lets any Pakistani citizen check how many SIM cards are registered against their own CNIC. Since every SIM in Pakistan must be linked to a CNIC through biometric verification, this system gives you a direct window into your own mobile identity — without needing to visit any office in person.
It exists for one simple reason: CNICs can be misused. A lost ID card, an old photocopy handed to the wrong person, or a family member registering a SIM without asking — any of these can result in numbers being tied to your identity that you never actually authorized. The SIM Information System is PTA’s way of putting that visibility back in your hands.
How the System Works: Step-by-Step
Method 1: The 668 SMS Check
- Open your messaging app on any phone with an active SIM.
- Type your 13-digit CNIC number without dashes (for example, 3520112345671).
- Send it to the short code 668.
- Wait for the automatic reply, which shows your total SIM count broken down by operator.
Method 2: The Online Portal
- Visit the official PTA SIM Information portal at cnic.sims.pk.
- Enter your CNIC number in the required field.
- Complete any verification step, such as a security code.
- View your results directly on the screen, often with more detail than the SMS reply.
Both methods pull from the same official database, so you’ll get consistent results whichever one you choose.
Understanding Your Results
Once you get your reply, here’s what to do with it:
- Compare the total count against the number of SIMs you personally use.
- Check the operator breakdown — Jazz, Zong, Telenor, Ufone, or SCOM — to see where any extra numbers might be.
- Note that the system typically shows counts, not full phone numbers. For specific numbers, you may need to visit your operator’s franchise with your CNIC.
If everything lines up with what you actually use, you’re in good shape. If the count is higher than expected, it’s time to investigate further.
Understanding the SIM Limit Per CNIC
PTA places a cap on how many SIMs a single CNIC can hold, largely to reduce fraud and misuse. As a general rule:
- A maximum of 5 SIM cards can be registered under one CNIC, combined across all networks.
- This means you cannot have 5 SIMs on one network and additional SIMs on another — the total across every operator is capped.
- If you’ve hit this limit and want a new SIM, you’ll typically need to disown or deactivate an existing one first.
Because rules and enforcement details can be updated by PTA over time, it’s always worth double-checking current limits directly through PTA’s official website if you’re near the threshold.
What to Do If You Find Unauthorized SIMs
- Visit the relevant operator’s franchise (Jazz, Zong, Telenor, Ufone, or SCO) with your original CNIC.
- Request formal disowning of the number you don’t recognize.
- Complete biometric verification, typically a quick fingerprint scan.
- Keep any receipt or confirmation you’re given for your own records.
- Recheck via 668 or the online portal after a few days to confirm the update was processed.
If your concern isn’t resolved at the franchise level, PTA’s official complaint portal is available to escalate the matter further.
