Biometric Verification (BVS): Check and Fix Your SIM’s Status (2026)
Biometric verification is the fingerprint check that ties every Pakistani SIM to a real person through NADRA. Each network has an official channel to confirm a SIM’s status: 6001 for Jazz, 7751 for Telenor, 7911 for Zong, and the code *336*1# for Ufone. A SIM that fails the check gets fixed at a franchise with your original CNIC and a thumb impression.

Biometric verification is the layer most guides skip, yet it is the reason Pakistan’s SIM registry means anything at all. A count is only as trustworthy as the fingerprints behind it. This page covers what the system does, the per-network status checks, one code the internet keeps getting wrong, and what to do when a SIM shows unverified.

What biometric verification means for SIMs
Since the nationwide re-verification drive of 2015, no SIM in Pakistan is meant to activate without a fingerprint matched live against NADRA’s database. The retailer scans your thumb. NADRA confirms the print belongs to the CNIC presented, and only then does the operator switch the SIM on. That match is what the Biometric Verification System, BVS, actually is.
The result lives on as the biometric-status field in your registry record, described alongside the other fields in our SIM card owner details guide. It is also what gives a 668 SIM check its weight: the counts are anchored to fingerprints, not paperwork. The registry storing it all is mapped in the SIM information hub.
Check your status: codes by network
| Network | What to do |
|---|---|
| Jazz | SMS your CNIC number to 6001 |
| Telenor | Send any SMS, even a blank one, to 7751 |
| Zong | SMS the letter V to 7911 |
| Ufone | Dial *336*1# from the SIM |
| SCO / others | Ask at the operator’s franchise or helpline |
Each check answers for the SIM you run it from, which keeps the whole family privacy-safe. Standard SMS charges can apply. The reply states whether the SIM’s registration is biometrically verified, and each network’s wider checks sit in the by-network hub.
The Ufone correction: *336*1#, not *336#
Here is the detail that separates checked guides from copied ones. Much of the internet, quoting older material, lists Ufone’s biometric check as *336#. PTA’s own official Facebook page carries the working version, and it is *336*1#. The difference is two characters. Dial the short version and the code simply shrugs.
We verified this against PTA’s post, not against other blogs. Small codes stay accurate no other way. If a guide you are reading still says *336#, treat everything else on that page with matching suspicion. Our editorial standards exist for exactly this class of error.
If your SIM shows unverified
- Do not wait. An unverified SIM risks suspension, and it is a loose thread in your identity either way.
- Take your original CNIC to the operator’s own franchise. Photocopies do not scan thumbs.
- Re-verify by fingerprint at the counter; the process is the same live NADRA match a new SIM gets.
- Confirm afterwards: run the network’s status code again, then a 668 SIM check to see the record whole.
While you are at the counter, settle anything else the audit surfaced. A SIM you never bought gets disowned in the same visit, with the six-step version in our CNIC SIM check guide, and the totals decoded in the count decoder.
Fake fingerprints: why BVS matters
The system earns its keep against a real adversary. In early January 2026, coverage of a nationwide FIA crackdown reported raids across two dozen cities that recovered 99 biometric devices and roughly 250,000 fake fingerprints. That tooling existed to activate SIMs on identities that never consented. That is the industrial version of the threat BVS was designed to stop.
Two lessons follow for ordinary users. First, the fingerprint layer is why a forged “registration” is hard and rare rather than easy and common. It also means checking your record actually settles the question. Second, the layer is not magic. Where fraud slips through, it shows up as an extra SIM in your count. That is why the monthly 668 habit and these status codes belong together. The legal consequences for the fraudsters run through Section 16 and its neighbours, covered in our PECA 2016 guide.
Biometric verification Roman-Urdu mein
Biometric verification wo fingerprint match hai jo har SIM ko NADRA ke record se jorta hai; 2015 se koi SIM iske baghair activate nahi hoti. Apni SIM ka status check karne ke liye: Jazz par CNIC likh kar 6001 par SMS, Telenor par koi bhi SMS (khali bhi chalega) 7751 par, Zong par V likh kar 7911 par, aur Ufone par *336*1# dial karein — *336# purana aur ghalat hai, sahi code PTA ke apne Facebook page par hai. SIM unverified nikle to asli CNIC le kar franchise jayein, angootha lagwayein, aur baad mein 668 se poora record dekh lein.
Biometric verification FAQs
How do I check my SIM’s biometric verification status?
From the SIM itself: Jazz, SMS your CNIC to 6001; Telenor, any SMS to 7751; Zong, SMS V to 7911; Ufone, dial *336*1#. The reply states whether the SIM is biometrically verified.
Is the Ufone biometric code *336# or *336*1#?
*336*1#. Older articles circulate *336#, but PTA’s own official Facebook page carries *336*1# as the working code, and that is the version we verified.
Does a blank SMS to 7751 really work for Telenor?
Yes. Telenor’s 7751 status check accepts any message, including an empty one, a detail confirmed on PTA’s official information page for the service.
What happens if my SIM is not biometrically verified?
It risks suspension and it weakens your identity record. Take your original CNIC to the operator’s franchise, re-verify by thumb impression, then re-run the status code and a 668 check to confirm.
Do eSIMs go through biometric verification too?
Yes. An eSIM activates against your CNIC with the same live NADRA fingerprint match as a physical SIM, carries the same status field, and appears in your 668 count identically.
