Method Guide · The SIM in Your Hand
667 SIM Check (MNP): Verify Any SIM in Your Hand, the Right Way
667 vs 668 comes down to two different questions. 667 confirms that the single SIM in your hand is registered. 668 counts every SIM on your CNIC, across all networks. Send the word MNP from that SIM to 667 at standard SMS rate; that one SMS is the whole MNP 667 check. PTA’s registry replies with the card’s registration status, checked against a masked identity. That identity is the NADRA-issued CNIC the line sits on, shown only in part. 667 and 668 are covered together here. The complete self-check toolkit lives at Check SIM Owner Details Pakistan.
Key takeaways
- Send MNP to 667 from the SIM being checked; the reply confirms registration status against a masked identity.
- 667 vs 668 in one line: 667 answers for one physical card; 668 counts every SIM on your CNIC. A full audit uses both.
- It cannot be aimed at a stranger’s number, because the SMS must leave the SIM itself.
- Run 667 before porting, after buying a used device, and on every drawer SIM you rediscover.
- Cost: your operator’s standard SMS rate. Works on Jazz, Zong, Telenor, Ufone and ONIC alike.
- New for porting: under reporting dated 24 July 2026, biometric verification with your original CNIC is required before an MNP transfer.
That is 667 vs 668 in practice: a 667 SIM check verifies your own card, and a 668 check audits your own record. Neither one exposes anyone else’s sim owner details. Hunting a stranger’s identity by any route is an offence under Section 16, mapped on our legality page. 667 and 668 are both self-check codes, and that is the only version of either that exists in law.

What the 667 SIM check is
What is the 667 SIM check in Pakistan?
667 is Pakistan’s SIM-verification short code, run inside the Mobile Number Portability framework on every major network. Text the single word MNP to 667 from the SIM you want checked, and PTA’s Subscriber Verification Management System replies with that card’s registration status against a masked identity. Most short codes talk about accounts or balances. 667 talks about identity, and that registry sits behind every legal check on this site.
The design has one property worth admiring. The query must travel from the SIM being checked, so the code carries its own consent. Possession of the SIM is what authorises the check. Nobody in Lahore can run this check on your Karachi number, and you cannot run one on theirs. Compare that with the fake “databases” our Pak SIM Data investigation documents. Those sites pretend consent does not exist, and they end up on the wrong side of the law. Brand names rotate while the pitch stays the same, as our Minahil SIM Data check shows. Their records usually come from a CNIC data breach, not from any legal registry.
That is also why 667 belongs in your pocket rather than your bookmarks. It travels with the SIM, works on a ten-year-old handset, and needs no internet. In half of Pakistan, that is the gap between a check you run and a check you postpone.
Running it: the 30-second routine
How do you check a SIM with the 667 code?
- Seat the SIM in any working handset. Give it a moment to catch signal. The phone’s brand does not matter; the card is what answers.
- Type the single word MNP in a new SMS. No CNIC, no number, no punctuation, nothing else.
- Send it to 667. Your operator’s standard SMS charge applies, usually a rupee or two.
- Read the reply. It lands within a minute or so. You get the SIM’s registration status, checked against a masked identity.
- Screenshot it with the date. The card may later go to a franchise for porting or correction. That screenshot is then your before picture.
This MNP 667 routine never changes across networks. That makes it a rare Pakistani telecom instruction: learn it once, reuse it forever.
Reading the reply, line by line
What does the 667 reply show?
The 667 reply is short by design, and every element earns its place. Expect two essentials. First, confirmation that the SIM is registered. Second, identity digits shown in masked form. Masking keeps the message safe even if the phone later lands in someone else’s hands. Field by field, our 667 SIM owner name guide maps the reply to what PTA’s MNP guidelines specify.
Read it against one question: does this match me? Masked digits that line up with your own CNIC mean the card is yours on paper as well as in pocket. Want the wider record those digits point to? Our guide on how to check your CNIC details covers the NADRA channels. A registered status against digits that cannot be yours means the card sits on someone else’s record. The honest next step is a franchise counter, not continued use. An unregistered or failed status means the card should not be in service at all.
What the reply never contains matters just as much. No full CNIC, no owner name for strangers, no address. The same privacy-by-design runs through 668 and cnic.sims.pk, described across our twelve official methods. Treat any service that promises fuller sim owner details from a bare number as the scam it is. Our by-number reality check explains why that door does not exist.
The sibling code: 668 in one minute
What is the 668 SIM check?
668 is the code that counts SIMs rather than verifying one card. SMS your 13-digit CNIC, with no dashes, to 668 for about Rs 2 including tax. PTA’s registry then replies with your SIM count on every network at once. One message covers Jazz, Zong, Telenor, Ufone and SCOM together. In a browser, the free PTA SIM Information System at cnic.sims.pk shows the same count with activation dates.
That wide view comes with one blind spot. 668 counts records rather than physical cards. It can tell you that five SIMs sit on your CNIC. It says nothing about whether the plastic in your drawer is one of them. That is exactly the gap 667 fills, and why 667 vs 668 works as a pair rather than a rivalry. The full 668 guide reads its reply line by line, and the count decoder handles every confusing total.
667 vs 668, side by side
What is the difference between 667 and 668?
667 vs 668 is a difference of scope. 667 verifies the single SIM that sends the SMS; 668 counts every SIM registered against your CNIC across all networks. 667 needs the card in hand and the word MNP, while 668 needs only your 13-digit CNIC and about Rs 2. Both read PTA’s Subscriber Verification Management System, so their answers should agree.
| Question | 667 | 668 |
|---|---|---|
| What it audits | The one SIM that sends the SMS | Every SIM on the CNIC you send |
| What you type | The word MNP | Your 13-digit CNIC, digits only |
| Reply contains | Registration status + masked identity | Per-network SIM counts |
| Cost | Standard SMS rate | About Rs 2 including tax |
| Needs the SIM in hand | Always | Never; any Pakistani SIM can send it |
| Free alternative | None needed; it is near-free | cnic.sims.pk, the official portal |
| Best moment | Before porting; on any doubtful card | Monthly identity audit |
The scope difference settles the 667 vs 668 confusion. Hold on to the deeper point, though. The two codes are two ends of one registry. One enters through the card, the other through the identity. Where their answers disagree, you have a finding worth taking to a franchise.
Five situations, solved
When should you run a 667 SIM check?
- The drawer SIM. A card surfaces during house cleaning. Seat it, send MNP to 667, and read the status. Then run 668 to see how many SIMs are on your CNIC and whether it still holds a slot. Two minutes, complete picture.
- The used phone. A bought device arrives with a SIM inside. Run 667 first. A card registered to someone else’s record has no business in your daily phone, however good the data package looks.
- The porting plan. Run the MNP check before you file the request. Registration surprises stall ports at the counter, never at home.
- The family hand-me-down. A parent’s spare SIM moves to a child’s phone. Verify it with 667. Then remember that ownership has not moved. Transfers happen at franchises with both CNICs, not by handing over plastic. PTA said again on 24 July 2026 that unlawful activity on a SIM is attributed to the person it is registered to. Our SIM sharing warning has the detail.
- The monthly ritual. Pair 668 on your CNIC with 667 on any card you doubt. The pair costs pocket change and closes the questions that matter. That is the whole idea behind our methods hub.
The porting-prep checklist
What should you check before porting your number?
Mobile Number Portability lets your number change operators while keeping its digits. 667 was built inside that machinery, so porting is its home turf. A clean port starts with a clean card.
- MNP to 667 from the number you are porting. Status must read registered, against digits that match your document.
- CNIC to 668 for the wide view. Your target network refuses a sixth voice SIM politely but firmly. The national cap is eight, five voice plus three data, set by the Supreme Court ruling of 5 November 2015.
- Biometric health check. An unverified SIM invites friction anywhere identity is re-checked. Your network’s status code takes a minute, and every code sits in our master code sheet. PTA’s enforcement orders of 13 and 16 July 2026 named biometric verification lapses at operators, logged in our enforcement roundup.
- Original CNIC in hand for the franchise visit. A photocopy cannot be scanned at the counter.
Is biometric verification required to port a number?
Porting itself now has a biometric step. Per the 24 July 2026 reporting, biometric verification with the original CNIC is required for mobile number portability, not only for a fresh connection. The same reporting extends it to duplicate SIMs, ownership transfer and SIM disowning, and asks operators to use Live Finger Detection devices. PTA has not published a numbered circular or dated regulation for this, so treat it as reported practice. Our breakdown of the tightened SIM issuance rules keeps the sources together.
One timing note from the current rules. Since PTA’s advisory of 24 May 2026, a newly activated SIM cannot be disowned or transferred for 365 days from activation. So pre-port checking is the cheap step, and post-port correction is the costly one. Our PTA news log tracks that rule with sources.
Three myths about 667, retired
Myth one: 667 reveals who owns any number. It cannot, and the reason is physical. The SMS must leave the SIM being checked. So the only identity 667 ever discusses with you belongs to a card in your own hands, and even that arrives masked. Full sim owner details for strangers sit behind no code at all. Our myths desk has tested that claim in every form doing the rounds.
Myth two: 667 is a Jazz thing, or a Telenor thing. The code is network-neutral because porting is network-neutral. Ufone’s own support pages document the MNP 667 flow. The routine is the same on Jazz, Zong, Telenor and ONIC.
Myth three: it costs real money. One standard-rate SMS, and that is all. Suppose a website or “agent” wants Rs 300 to run a SIM verification for you. That is the same pitch behind the “live SIM tracker” apps, which charge to locate a number they cannot legally find. Anyone charging for that is running a scam. The free-and-official table on our codes master sheet is the antidote.
No reply? The fix ladder
Why did 667 not reply?
If 667 sends no reply, the usual causes are extra words in the message, a SIM with no service, or short-code congestion at peak hours. Re-send the single word MNP after a few minutes, and call your operator’s helpline from that SIM if the silence continues. The reply itself carries no charge, so a missing answer is a delivery problem, not a billing one.
- Check the message body. The word MNP alone, nothing else. Extra words are the most common silent killer.
- Check the SIM’s service. A card with no signal or suspended service cannot SMS a short code. Give it a minute on the network first.
- Wait, then re-send once. Short-code queues congest at peak hours. A few minutes of patience beats five duplicate messages.
- Escalate to the operator’s helpline from the affected SIM if silence persists. Helplines can read what the code reads.
- For a card that fails everything, the franchise counter with your original CNIC is the last stop. If the card turns out not to be yours at all, the disowning walkthrough in our methods hub takes over.
Frequently asked questions
What does the 667 SIM check actually reply with?
Registration status for the SIM that sent the SMS, checked against a masked identity. You learn two things: whether the card is registered, and whether the visible fragment matches your own document. The reply carries no full CNIC and no address. It never says anything about a third party.
Can I run a 667 SIM check on someone else’s number?
No. The MNP 667 message must leave the SIM being checked. So the code cannot be pointed at a number you do not hold. That design is why 667 stays legal while lookup sites do not. Possession is the only key, and it is not one you can fake from a distance.
How much does 667 cost?
Your operator’s standard SMS rate, usually a rupee or two. The reply itself is free. Compare that with 668, which costs about Rs 2 including tax and answers a different question. No website or agent needs to charge you extra. Both codes run straight from your own phone.
Which should I use before porting my number?
667 first, from the SIM you plan to port. A registration mismatch shows up in the reply before you file the request. That is exactly when it is cheap to fix, at a franchise with your original CNIC. Run 668 too, since your new network will refuse a port that breaks the eight-SIM cap.
Do I need biometric verification to port my number now?
Yes, under instructions reported on 24 July 2026. Biometric verification with your original CNIC now covers mobile number portability, duplicate SIMs, ownership transfer and disowning. PTA has not published the formal text, so treat it as reported practice. Run MNP to 667 at home first, then visit the franchise.
I found an old SIM in a drawer. 667 or 668?
Both, in that order. Insert the SIM and send MNP to 667 to learn its status. Then SMS your CNIC to 668 to see whether it still counts against your identity. Unfamiliar entries route through franchise disowning. Together the two checks cost pocket change and take about two minutes.
Does 667 show the owner’s name of a found SIM?
No. It confirms registration against a masked identity, which tells you whether the card matches your own document. It is not a tool for identifying strangers. Pulling a stranger’s sim owner details by any route is an offence under PECA Section 16, so the answer never arrives as a name.
Why did 667 send no reply?
Three usual causes: the SIM has no service, the message carried extra words, or the network queued the short-code traffic. Re-send the single word MNP after a few minutes. Use the operator helpline if the silence continues. A card that fails every attempt belongs at a franchise counter with your original CNIC.
667 vs 668: do they read the same database?
Yes. Both read PTA’s Subscriber Verification Management System. 667 enters it from a SIM, and 668 enters it from a CNIC. Together they audit the card and the record in about two minutes. One answers for the plastic in your hand, the other for the identity on your document.
Roman Urdu mein
667 SIM check ka kaam aik hi hai: jo SIM aap ke haath mein hai, us ki registration ki tasdeeq. Us SIM se sirf MNP likh kar 667 par SMS karein, standard SMS rate par. Jawab mein registration status aur masked shanakht aati hai. Kisi ajnabi ka naam kabhi nahi aata. Porting se pehle, purana phone khareedne par, aur drawer se nikli har SIM par yeh check zaroor chalayein. Poora hisaab chahiye to apna CNIC 668 par bhejein. Har network ki ginti aik hi reply mein aa jaati hai. Dono codes wahi PTA registry parhte hain, aur dono sirf aap ke apne record ki baat karte hain.
