Check Blocked SIMs on CNIC: What 668 Shows, What the Operator Confirms
No single code lists your blocked SIMs. To check blocked SIMs on CNIC you work in three steps. 668 and cnic.sims.pk show what is registered, not what is blocked. The count comes from 668, the dates come from the portal, and a line’s real status comes from that network alone. The full self-check toolkit sits at Check SIM Owner Details Pakistan.
Key takeaways
- 668 costs about Rs 2 and returns your SIM count at each network. It carries no blocked label.
- PTA’s free cnic.sims.pk portal shows the same counts on a dated table, works worldwide, and takes NICOP.
- Line status sits with the operator: Jazz 111, Zong 310, Telenor 345, Ufone 333.
- Work in that order, count then dates then status, and nothing slips through.
- Most blocks trace to biometrics, an expired CNIC, or an enforcement sweep.
Scope: every method here reads your own record with your own CNIC. Probing someone else’s lines is a crime under PECA Section 16. Our legality page draws that line in full.

What 668 and the portal actually show
Honest scope first: as of August 2026, neither channel prints a blocked list. SMS your 13-digit CNIC, digits only, to 668 for about Rs 2. The reply is your SIM count at each network. PTA’s free cnic.sims.pk portal shows the same roster worldwide and adds every line’s activation date. That is the whole offer. No column in either reply says active, suspended or blocked.
So the phrase people type, check blocked SIMs on CNIC, asks for a list that no official channel prints. What you do get is still enough: a roster to compare against, and dates that make a stale or strange entry stand out. The verdict on any one line rests with its network. Sending rules and reply quirks live in the 668 guide. What a bare number can and cannot reveal about its owner is a separate question, answered on the sim owner details by number page.
What each channel can and cannot tell you
| Channel | What it returns | Shows a block? |
|---|---|---|
| SMS CNIC to 668 | Your SIM count at each network. | No. |
| cnic.sims.pk portal | The same roster on a dated counts table. | No. |
| SMS N and the number to 76367 | The network that number sits on today. | No. |
| 8484 (DIRBS) | Whether a handset IMEI is cleared for use. | Handset only, not the SIM. |
| Operator helpline or franchise | The live state of one named line. | Yes, with the reason. |
The last two rows save a lot of wasted effort. Many people say blocked SIM when the block really sits on the handset, and a phone barred under DIRBS stays offline whichever SIM you feed it. Dial *#06# to read the IMEI, then check the device record first.
The three-step triangulation
That is how you check blocked SIMs on CNIC: count, then dates, then status. Treat the job as a relay with three legs. Each leg hands off to the next.
| Step | Channel | Cost | What it settles |
|---|---|---|---|
| 1 | SMS your CNIC to 668 | About Rs 2 | How many SIMs each network holds against your CNIC. |
| 2 | cnic.sims.pk portal | Free | The start date of every line, so dormant entries stand out. |
| 3 | Operator helpline or franchise | Free call | Whether one line is active, suspended or blocked, and why. |
Step three is where the word blocked finally gets an official answer. Call from another phone if the suspect SIM is dead, and keep your CNIC to hand for the check. Ask for the block reason on record, because the reason decides the fix. A count you cannot explain belongs on the count decoder before anything else.
A worked example
Say 668 replies with four Jazz SIMs and one Zong SIM, while you only recall buying three in all. Open cnic.sims.pk next and read the dates. Two Jazz lines start in the same week of 2019, and you remember just one of them. That gap is your lead. Call Jazz on 111 and ask about the older of the two, and the agent can say whether it is active, suspended or blocked. If you cannot even name your own numbers yet, start with the own-number codes instead.
Check the total while you are there. The cap per CNIC is eight SIMs: five voice and three data, under a Supreme Court ruling of 5 November 2015. A count above the cap is a red flag, and so is any count you cannot place.
Why SIMs get blocked in the first place
Three causes cover most blocks: unfinished or failed biometrics, an expired CNIC, and an enforcement sweep. PTA’s advisory of 8 April 2026 tied 8.1 million SIMs to expired cards alone. Biometrics lead. A SIM whose check never finished sits suspended, and so does one that failed a re-verification round. A live thumb at the franchise clears it. Channels and status codes are set out in the BVS guide.
The document behind the SIM is the second trigger. It helps to first confirm what your CNIC record actually holds. An expired card puts every line on it in the enforcement queue. Renewal is the way back, and the order is set out on the expired-CNIC page.
Third come enforcement sweeps. They target fraud numbers and lines left in a dead owner’s name. Across the enforcement year from July 2024 to June 2025, 3.2 million SIMs were blocked. Our deceased-CNIC blocking report unpacks that figure. A late relative’s lines follow the heirs’ route on the deceased-person SIMs page.
Not every dead line is a blocked line
- No signal is not proof of a block. Try the SIM in a second handset before you assume the worst.
- A second new SIM on one CNIC has to wait seven days. PTA set that wait from 24 January 2024, and a delay is not a block.
- A new SIM cannot be disowned or transferred for 365 days. PTA fixed that lock in an advisory dated 24 May 2026.
- A line you stopped topping up may simply have lapsed, so ask the operator whether it lapsed or was blocked.
Getting a straight answer from the operator
The network holds the status, so ask the network. Helplines first: Jazz 111, Zong 310, Telenor 345, Ufone 333. Call from the SIM if it still catches signal, and use any other phone if it does not.
Where the doubt is biometric, each network runs a status channel of its own. On Jazz, send your CNIC to 6001, and on Telenor send a blank SMS to 7751. On Zong, send the letter V to 7911, and on Ufone dial *336*1#. Each of these self-check channels is one entry in the wider catalogue of official methods.
When the line is fully dead, a franchise visit beats every call. The fix usually needs your thumb anyway. That covers re-verification, proof of ownership and renewal papers. Take the original CNIC. Photocopies start arguments. Originals end them.
Common mistakes when you check blocked SIMs on CNIC
- Reading the 668 reply as a status list. It is a count, and no part of it says blocked.
- Trusting codes such as *321# or *345# that stray posts sell as blocked-SIM checkers. Those are not the channels PTA or the networks use for this job.
- Paying a website to check or clear a block. Every official route here is free or costs about Rs 2, and those paid data sites are the problem rather than the fix, as our SIM database page explains.
- Installing a “live tracker” app to read a SIM’s status or location. Our test of live SIM tracker claims shows what those apps really do.
- Sending the CNIC to 668 with dashes in it. Send the 13 digits and nothing else.
- Sending a relative’s CNIC to 668 to audit their lines. That record is theirs to pull, not yours.
If a line really is blocked: your routes
The recorded reason routes you. Failed or missing biometrics mean a franchise, a live thumb and a few minutes. An expired CNIC means NADRA renewal first and the operator second, in that order. The expired-CNIC page walks through it. A line you still want can often come back. Our reactivation guide carries the honest caveat that networks quote reactivation windows differently, so confirm the exact window with yours.
Two branches deserve their own pages. A blocked line you never bought is an incident, and often the fingerprint of a CNIC data leak. The unauthorised-SIM page handles it. The formal steps sit in the block and disown guide. Lines you simply no longer want are cheaper to deactivate on your own schedule than to leave for a sweep. Blocked by choice always beats blocked by surprise.
If the operator will not settle it
Escalate in a fixed order, and keep every reference number. Start with the helpline and ask for a complaint number. Take the franchise route next, with your original CNIC in hand. If the answer still does not come, PTA takes complaints on 0800-55055. PTA has also run a WhatsApp Digital Assistant on 0315-0055055 since 26 February 2026.
Where fraud sits under the block, the case is bigger than one SIM. The National Cyber Crime Investigation Agency has been live since 3 June 2025, and it takes reports on 1799 and at complaint.nccia.gov.pk. Cost is rarely the barrier. PTA capped the fee for disowning a SIM at Rs 200 from 1 January 2024, and waived it where fraud is proven.
Roman Urdu mein
CNIC par blocked SIMs check karne ka sach seedha hai. 668 (taqreeban Rs 2) sirf ginti batata hai. cnic.sims.pk wohi ginti muft mein, dated table par deta hai (per-SIM dates nahi). Blocked ka label dono jagah nahi hota. Kisi line ka asal status us operator se milta hai: Jazz 111, Zong 310, Telenor 345, Ufone 333. Tarteeb yeh rakhein: pehle 668 se count, phir portal se dates, aakhir mein helpline ya franchise se status aur block ki wajah. Block aksar teen wajah se lagta hai. Biometric adhoora, CNIC expire (8 April 2026 ki advisory mein 8.1 million SIMs), ya enforcement sweep. Wajah maloom ho jaye to hal bhi saaf nazar aata hai. Yaad rahe, kisi doosre ke SIMs check karna PECA Section 16 ke tehat jurm hai.
Frequently asked questions
Does 668 tell me which of my SIMs is blocked?
No. The 668 reply is only a count of the SIMs held against your CNIC at each network. There is no status column and no blocked flag in it. Treat that reply as your roster. The verdict on any single line comes from that operator’s own helpline or franchise.
Can cnic.sims.pk show a SIM’s blocked status?
No. The portal shows a dated per-network counts table, free and from anywhere in the world — counts only, never per-SIM activation dates (first-hand check, 30 August 2026). Blocked status is not on the page at all. The portal reads the PTA registry, while a block is a state the operator holds.
Is there a code to check blocked SIMs on CNIC?
No single code to check blocked SIMs on CNIC exists. 668 gives you a count for about Rs 2, and cnic.sims.pk gives you dates for free. Neither one prints a blocked list. Codes shared online as blocked-SIM checkers are not official channels. Only your network can confirm the state of a single line.
Why did PTA block my SIM suddenly?
Usually one of three reasons. The biometric check was never finished, or it failed. The CNIC behind the SIM expired, and an advisory of 8 April 2026 put 8.1 million SIMs in that bucket. Or an enforcement sweep caught the line. Your operator can read the exact reason on record.
My CNIC has expired. Are all my SIMs blocked now?
Not automatically, and not all at once. Lines on expired CNICs are an active PTA enforcement target, so treat it as a countdown. Renew with NADRA first. Then ask your operator to refresh your record. Our expired-CNIC guide covers the order of operations.
Does 76367 show whether a number is blocked?
No. Send N and then the number to 76367, and you learn one thing only. The reply names the network that number sits on right now, for about Rs 2. It never returns an owner name, and it never returns a blocked or active status.
Can I unblock a SIM without visiting a franchise?
That depends entirely on the cause. Some renewal-related blocks clear once NADRA data syncs across. Biometric blocks need a live thumb at the counter by design. Call the helpline first and ask for the recorded reason. That one answer tells you whether the trip is avoidable.
What does it cost to disown a SIM I never bought?
No more than Rs 200. PTA capped the disowning fee at that figure on 1 January 2024, and the fee is waived where fraud is proven. Report the line to your operator first, and keep the complaint number. New SIMs also carry a 365-day disowning lock, set by PTA on 24 May 2026.
