Short Answer: Send your 13-digit CNIC number via SMS to 668 and wait for the reply showing the number of SIMs registered on your CNIC.
A 668 sim check tells you exactly how many SIMs are registered under your CNIC, pulled straight from PTA’s own records. You can run this check right now, in under a minute, and it costs almost nothing.
What Is the 668 SIM Check?
668 is a short code run by the Pakistan Telecommunication Authority (PTA). It taps into the SIM Information System, the official database that links every registered SIM in Pakistan to the CNIC it was issued against. When you send your CNIC to 668, you get back a fresh, live count of how many SIMs sit under your name, broken down by network.
How to Do a 668 SIM Check by SMS
- Open your messaging app.
- Type your 13-digit CNIC number, with no dashes or spaces.
- Send it as an SMS to 668.
- Wait for the reply. It usually arrives within a few seconds and shows how many SIMs you have on each network.
A small SMS charge applies, usually around Rs. 2 plus tax, similar to any other text message.
Check the Same Fresh SIM Database Online
If you’d rather not use SMS, PTA runs the exact same database through a website: cnic.sims.pk. This is genuinely useful if you’re outside Pakistan, since it works from any country with an internet connection.
- Go to cnic.sims.pk in your browser.
- Enter your 13-digit CNIC number, without dashes.
- Complete the CAPTCHA to confirm you’re not a bot.
- Submit the form to see your results instantly.
It’s free, and you don’t need to create an account.
What You’ll See in Your Results
Both methods show you the same thing: a count of SIMs registered under your CNIC, broken down by network (Jazz, Zong, Ufone, and others). This is a straightforward number, not a name or a full phone number, since PTA’s system is built to protect that information. You’ll know how many SIMs are yours, which is exactly what you need to spot something wrong.
What If You Find a SIM You Don’t Recognize?
This is the whole point of running the check in the first place. If your result shows more SIMs than you actually own or use, here’s what to do:
- Note which network the extra SIM belongs to.
- Visit that network’s franchise or customer service center with your original CNIC.
- Ask for biometric verification and request the SIM be blocked or corrected.
- If it isn’t resolved, file a complaint directly with PTA.
A Couple of Rules Worth Knowing
Every CNIC in Pakistan can have a maximum of five SIMs registered against it, prepaid or postpaid combined. Also, this check is meant for you to look up your own CNIC only. Checking someone else’s SIM count without their permission isn’t something the 668 service or the PTA portal is built for, and doing so goes against Pakistan’s telecom and cybercrime rules.
Other Official Ways to Check
A couple of extra options exist if 668 or the website isn’t working for you:
- RAABTA, PTA’s WhatsApp assistant. Message it at 0315-0055055 and follow the prompts, useful if you don’t have a Pakistani SIM handy.
667, a different short code that checks the registration details of whichever SIM is currently in your - phone, rather than your full CNIC count.
Frequently Asked Questions
Does the 668 SIM check cost anything?
Yes, a small SMS charge applies, roughly Rs. 2 plus tax. Checking online at cnic.sims.pk is free.
Can I use 668 to check someone else’s SIMs?
No. It only returns results for the CNIC you send. Checking another person’s SIM count isn’t permitted.
Is cnic.sims.pk the same database as 668?
Yes. Both pull from the same official PTA SIM Information System, just through different access methods.
Can overseas Pakistanis use this service?
Yes. The cnic.sims.pk website works from any country, and PTA’s RAABTA WhatsApp assistant is built for exactly this kind of access without needing a local SIM.
What should I do if I find a SIM I didn’t register?
Visit the relevant network’s franchise with your original CNIC, ask for biometric re-verification, and request the SIM be blocked. File a complaint with PTA if it isn’t sorted out.
