How To Check SIM Owner Details In Pakistan
Every free, PTA-approved way to find out which SIMs sit on your CNIC — picked apart step by step, with no guesswork and no CNIC ever handed over to us. Whether you're doing a routine check or chasing down a number that's been calling you, this page covers every legitimate path forward.
Every SIM sold in Pakistan is tied to the buyer's CNIC through PTA's biometric verification system, which means the information about who owns a given number already exists — the only real question is which free channel to use to see it. This guide walks through all four that PTA officially recognizes, plus what the results actually mean and what to do if something looks wrong.
We'll start with the two methods that work for checking everything registered on your CNIC, move into the quicker but narrower operator-specific codes, and close with what your results should show and how to act on them. If you'd rather jump to a specific step, use the chooser above.
One important boundary before we start: every method below is built for checking SIMs on your own CNIC. There's no legal channel — through PTA, an operator, or this site — for checking someone else's registration without their consent, and any page that offers to do that for a fee should be treated as unsafe rather than convenient.
This guide covers roughly the same ground you'd find on a PTA help page, but organized around the question people actually search for — "how do I check this" — rather than around PTA's own internal department structure. If you're already familiar with one method and just need a refresher, the quick chooser above will take you straight there without scrolling through the rest.
📱 Method 1 — SMS Your CNIC To 668
This is PTA's original and still most widely used verification channel, working identically across every network in the country, and it remains the default recommendation for most people asking how to do this for the very first time.
- 1Open your phone's default SMS app — any handset with signal works, smartphone or not.
- 2Type your 13-digit CNIC number with no dashes, spaces, or extra characters.
- 3Send it to 668, PTA's dedicated national shortcode.
- 4Within seconds, you'll receive a reply listing every SIM registered on your CNIC, grouped by network.
- 5Reply with any unfamiliar number to trigger an emergency block request immediately.
The reply groups results by network, so if you have SIMs across two or three different operators, all of them will appear together in the same message, each clearly labeled — no need to run separate checks per operator.
🌐 Method 2 — PTA's Online Portal
For a fuller, printable version of the same information, PTA maintains its own dedicated web portal at cnic.sims.pk.
- 1Open the portal in any browser — desktop or mobile both work fine.
- 2Enter your 13-digit CNIC carefully, double-checking for typos before submitting.
- 3Complete the on-screen CAPTCHA to confirm you're not an automated script.
- 4Review the full report — every network, activation date, and current status in one place.
- 5Save or print the page if you'll need documentation for a complaint later.
Because this pulls straight from PTA's central registration system, it's generally treated as the most authoritative single record — useful if you ever need to attach proof to a formal complaint.
The portal also tends to load fine on slower connections, since it's a fairly lightweight government page rather than a media-heavy site, so it remains a reasonable option even on a modest 3G signal.
Operator-Specific USSD Codes
Every network also runs its own quick dial code, but with one key limitation: it only tells you the number of the SIM currently in your phone, not everything registered on your CNIC. Think of these as a convenience shortcut, not a replacement for a full check.
| Network | Code | Customer Care |
|---|---|---|
| Jazz | *99# | 111 |
| Zong | *100# | 310 |
| Telenor | *345*5*2# | 345 |
| Ufone | *333# | 333 |
If you specifically use Zong, our dedicated Zong SIM owner details guide covers this operator in more depth, including how the *100# menu behaves and when to fall back on 668 instead.
These codes are worth knowing for everyday convenience — confirming your own number before sharing it, or checking balance without opening an app — but they're not a substitute for a full CNIC-wide check whenever you're specifically investigating unauthorized registrations.
🏢 Method 4 — Visit A PTA Office Or Franchise
The slowest option, but the most hands-on — useful specifically when you need something blocked immediately or want written confirmation in hand. It's also the right choice if either of the digital methods above gave you an unexpected error and you'd rather resolve things with a person directly.
- 1Bring your original CNIC — a photocopy will not be accepted by staff.
- 2Locate the nearest PTA regional office or any authorized operator franchise.
- 3Ask staff for a complete list of SIMs registered under your CNIC.
- 4If anything looks unauthorized, request the blocking process be started on the spot.
How The Four Methods Compare On Speed
A rough visual sense of how quickly each method typically gets you a usable result, from fastest to slowest.
Speed isn't everything, though — the portal and in-person visit both give you something to hold onto (a printout or written note) that the SMS method doesn't, which matters if you're planning to file a complaint afterward.
A practical rule of thumb: use 668 for a routine check you'll do every few months, and reserve the portal or an in-person visit for the moment you actually need documentation — whether that's for your own peace of mind or for a formal PTA complaint.
What Information Actually Shows Up
Regardless of which method you use, a typical result includes the same core fields — knowing what to expect makes it much easier to spot when something in a result looks off.
- Registered Name
- The name on file with NADRA against that CNIC, matched exactly as it appears on official records
- Mobile Number
- The 11-digit number tied to each SIM entry currently registered
- Network
- Which operator issued the SIM — Jazz, Zong, Telenor, or Ufone
- Activation Date
- Roughly when the SIM was first registered under that CNIC
- Status
- Whether it's currently active, blocked, or deactivated by the operator
- Total Count
- How many SIMs in total sit on that CNIC across every network
If any field in your result looks genuinely inconsistent — a network you've never used, an activation date from years before you got your current CNIC — that's worth treating as a signal to move to the unauthorized-SIM steps further down this page, rather than assuming it's a display glitch.
A Few Terms Worth Knowing
If some of the terminology above feels unfamiliar, here's a quick reference for the ones that come up most — worth bookmarking if you're helping a family member through this process too.
- CNIC
- Computerized National Identity Card — the 13-digit ID every Pakistani adult holds, and what every SIM is legally tied to under current regulation
- USSD Code
- A short code like *100# that opens a quick menu directly on your phone, no app or internet connection needed
- Biometric Verification
- Fingerprint-based confirmation required to register or re-verify a SIM under current PTA rules, designed to prevent registration under a stolen identity
- PECA 2016
- Pakistan's Prevention of Electronic Crimes Act, which governs unauthorized access to personal data including SIM records and carries criminal penalties for violations
- Disowning A SIM
- The formal process of removing a SIM from your CNIC once it's confirmed unauthorized, distinct from simply blocking active use
- SIM Cap
- The maximum number of SIMs PTA permits per CNIC across all networks combined, confirmed and enforceable through court-backed regulation
Found A SIM You Didn't Register?
Don't leave it sitting there. Reply to 668 with the unfamiliar number to block it immediately, then follow through with a formal complaint so it's properly removed from your CNIC rather than just suspended. We've written a complete, step-by-step process for exactly this situation — including realistic timelines and what to do if it involved financial fraud — in our guide on removing an unauthorized SIM.
Since PTA's 2026 policy update, a registered SIM generally can't be disowned for a full year from its registration date, which makes catching and reporting a fraudulent one early meaningfully more valuable than it used to be under the older rules.
