cnic.sims.pk — The Complete PTA SIM Information Guide
cnic.sims.pk is PTA's official web-based version of the SIM Information System — the same national registry that 668 queries by SMS, accessible instead through any browser. This guide covers exactly how to use it, what it shows that SMS doesn't, and how to tell the real portal apart from lookalike scam sites.
What cnic.sims.pk Actually Is
cnic.sims.pk isn't a third-party checker or an operator tool — it's PTA's own official website, built as the web equivalent of the 668 SMS shortcode, drawing from the exact same national subscriber registry.
Where 668 sends your CNIC as a text message and gets a short SMS back, cnic.sims.pk lets you type your CNIC into a form on a webpage and view the result directly in your browser. Both methods query the identical underlying database — the one every operator checks during biometric SIM registration — so neither one is more "official" or more accurate than the other. The difference is entirely about the channel: one needs SMS balance and signal, the other needs a data connection and a browser.
The portal tends to be the better choice when you want a result you can screenshot or save, when your CNIC has enough SIMs registered that an SMS reply would need to split across two messages, or when you're troubleshooting a failed SMS attempt. If your 668 text isn't going through at all, our guide on 668 SIM Check Not Working covers the SMS-specific causes — this page focuses purely on the web portal itself.

Do's And Don'ts When Using The Portal
✅ Do
- ✓Type or bookmark cnic.sims.pk directly rather than clicking search ads.
- ✓Check that the connection shows a secure padlock before entering your CNIC.
- ✓Use it on a private, trusted network rather than an unfamiliar public Wi-Fi.
- ✓Cross-check a surprising result with the 668 SMS method if something looks off.
- ✓Close the tab after you're done, especially on a shared or public device.
🚫 Don't
- ✕Enter your CNIC on any domain that isn't exactly cnic.sims.pk.
- ✕Download an app claiming to be the "official" version of this checker — no app exists for it.
- ✕Pay anyone claiming to run this lookup for you for a fee — it's completely free.
- ✕Share a screenshot of your full result publicly, since it reveals registered numbers.
- ✕Enter someone else's CNIC without their knowledge or consent.
What The Portal Shows That SMS Sometimes Doesn't
Both channels pull from the same registry, but the web format has a few practical advantages worth knowing about.
Every SIM appears together without the risk of a long list splitting across two separate SMS messages the way 668 sometimes does.
Because it's a webpage, you can screenshot, print, or export the result as a PDF — useful for complaints or franchise documentation.
Works entirely over data, sidestepping SMS-specific issues like bundle exclusions, weak signal, or a temporarily busy shortcode gateway.
Same Five Networks, Same Underlying Data
Because cnic.sims.pk and 668 both query PTA's single national registry, the portal covers every operator identically to the SMS shortcode.
cnic.sims.pk vs. 668 SMS — Which Should You Use?
🌐 cnic.sims.pk
The better choice when you want a saveable, printable result, when you're checking from a device without an active SIM at all, or when SMS has already failed for some reason. It needs a working internet connection and a modern browser, and it's marginally slower to open than firing off a single text.
📩 668 SMS
Faster in most cases and works with zero data connection, which makes it the better fallback in areas with weak internet but working cellular signal. Its main limitation is that a long SIM list can split across two messages, and there's no easy way to save the result beyond keeping the text thread itself.

Troubleshooting cnic.sims.pk
Use responsibly: cnic.sims.pk is meant for checking SIMs registered against your own CNIC. Entering someone else's CNIC without their consent falls outside its intended use and can raise legal issues under the Prevention of Electronic Crimes Act (PECA) 2016. If you spot an unfamiliar SIM in your result, don't try to resolve it informally — follow our guide on removing an unauthorized SIM, and file a report with the NCCIA if fraud is confirmed.
Frequently Asked Questions
Is cnic.sims.pk free to use?
Yes — it's a free official PTA service with no subscription, login, or per-check fee of any kind.
Do I need to create an account to use it?
No — you simply enter a CNIC and submit; no registration, email, or password is required.
Is the data on cnic.sims.pk different from what 668 shows?
No — both draw from the exact same PTA national registry, so results should match; if they ever differ, it's usually a brief sync delay rather than conflicting data.
Can I use cnic.sims.pk from outside Pakistan?
Yes — unlike 668, which needs a local SIM with signal, the web portal only requires an internet connection, making it the better option while travelling abroad.
Is there an official mobile app version?
No official standalone app exists for this specific service — access it only through a browser at the exact web address.
Why does the site ask me to solve a captcha?
It's a standard anti-abuse measure to prevent automated bulk lookups against the registry, not an indication of anything wrong with your CNIC or account.
Can I check an eSIM through the portal?
Yes — eSIMs are registered against your CNIC the same way physical SIMs are, so they appear in the same result list.
Does the portal show who physically registered each SIM?
It shows the operator and status for each SIM, not the identity of the person who completed registration at a franchise counter.
How often can I check my CNIC on the portal?
There's no meaningful restriction on checking your own CNIC — you can run it as often as you need to.
What should I do if the portal and 668 give different results?
Wait a short while and recheck both, since a very recent registration or removal can take time to sync everywhere — if the mismatch persists, contact your operator to confirm the correct current state.
