How To Block Or Disown An Unauthorised SIM On Your CNIC

You send your CNIC to 668, and the reply comes back with a number you don't recognise sitting quietly next to your own. Maybe it's been there for a year. Maybe you have no idea when it appeared. Either way, the instinct is to panic and call your operator's helpline, sit on hold, and get told to "visit the franchise." That's actually correct advice, but it's usually delivered without any of the details that make the visit go smoothly — what to bring, what it costs, what to say, and, crucially, what to do if the person behind the counter tells you it "can't be done." This guide is that missing detail, written the way I'd walk a friend through it in person.

Before the walkthrough, here's the current shape of the rule, because it changed this year and a lot of people are still working from an older version of it.

Why An Unauthorised SIM Ends Up On Your CNIC

It's rarely one single dramatic event. In most cases it comes down to one of three quieter failures. Someone at a franchise processes a new connection using a photocopy of your CNIC instead of your live fingerprint, skipping the biometric match that's supposed to be mandatory under NADRA's verification system. Or a family member registers a SIM in your name "for convenience" years ago and never mentions it again. Or, less innocently, your CNIC copy ends up in the wrong hands after being submitted for something unrelated — a rental agreement, a loan application, a job form — and someone uses it to open a connection they then use however they like.

Whatever the route, the fix on your end is the same. You don't need to know how it happened to remove it; you just need to identify it and act. If you haven't already, run the check yourself by texting your CNIC number to 668, or use the cnic.sims.pk portal if you'd rather see it on a screen than in an SMS reply.

What Disowning Actually Costs

This is the part most people get wrong, usually because a franchise agent quotes a fee without asking why you're there. The cost depends entirely on the reason.

If a franchise tries to charge you for removing a SIM you're reporting as fraudulent, that's worth pushing back on. Ask for the fee waiver explicitly and mention that you're disowning it as an unauthorised registration, not a voluntary surrender — the distinction is what determines the charge.

The Franchise Walkthrough, Step By Step

This is the part nobody explains in enough detail. Here's exactly what the visit looks like from the moment you walk in.

1. Pick an authorised franchise, not a roadside SIM stall. It needs to be an official outlet of the operator whose network the fraudulent number is on — check the number's operator first if you're unsure by sending it to 76367, which replies with the current network.
2. Bring your original CNIC. Photocopies are not accepted for this process, since the whole point is a live biometric match against NADRA's records.
3. Ask specifically for "SIM Disowning," not just "I want to remove a number." Using the correct term gets you routed to the right desk faster.
4. State the reason clearly: "I never registered this SIM, and I want to disown it as an unauthorised connection." This phrasing matters for whether a fee applies.
5. Complete the biometric fingerprint scan against your CNIC. This confirms you are who your CNIC says you are, and lets the system match the disowning request to the right identity.
6. Sign the disowning form the staff prepare, and ask for a copy or a reference/receipt number before you leave. Don't skip this — it's your proof the request was filed if anything is disputed later.
7. Re-check via 668 within 48 hours. The franchise-level action is usually logged quickly, though full removal from PTA's national database can take longer to fully reflect.

The 365-Day Rule Nobody Explains Properly

Here's something that trips a lot of people up, and it's genuinely new. PTA is reported to have extended the minimum age before a SIM can be formally disowned or transferred from 60 days to a full 365 days, as part of its 2026 policy tightening. In plain terms: a SIM activated recently, even one you know is fraudulent, may not be immediately eligible for the standard disowning process at some operators until it's been active for a year.

This doesn't mean you're stuck waiting with no options. If the SIM is fraudulent and recent, you can still: report it to your operator to have it flagged and restricted, file a complaint through PTA's Complaint Management System at complaint.pta.gov.pk or the helpline 0800-55055, and, if it's actually been used against you, involve NCCIA in parallel rather than waiting out the year. The 365-day rule governs the formal, permanent disowning transaction — it isn't meant to leave a fraud victim with zero recourse in the meantime.

What To Bring, Checked Off

A wasted trip is the most common complaint about this process, almost always because something was missing. Tick what you've already got ready — nothing here is stored or sent.

If The Franchise Refuses Or Stalls

Occasionally a franchise will push back — claiming the process "isn't available today," or trying to charge a fee that shouldn't apply, or simply being unhelpful about a request that doesn't earn them anything. You have a real escalation path, and it's worth using rather than giving up and trying a different branch and hoping for better luck.

• Note everything on the spot: the franchise name, its location, the date, and the staff member's name if they gave one.
• File a formal complaint at complaint.pta.gov.pk or call 0800-55055, describing exactly what happened and what was refused.
• Mention PTA's recent enforcement activity if it comes up — the regulator has fined operators significant amounts over exactly this kind of franchise-level non-cooperation, so this isn't an empty complaint channel.
• Ask for a complaint reference number and use it to track the outcome through the same portal.

A Quick Real-World Walkthrough

Bilal checks his CNIC through 668 out of habit one evening and sees three numbers instead of the two he actually owns. The third has been active for around eight months, on a network he doesn't use. He writes the number down, confirms the operator by texting it to 76367, and goes to that operator's franchise the next morning with his original CNIC.

At the counter, he says exactly what he needs: an unauthorised SIM disowning request, not a general complaint. The agent runs his fingerprint, matches it against his CNIC, and processes the disowning. Bilal asks for the reference slip before leaving. Two days later, he checks 668 again — the number is gone. The whole visit takes under twenty minutes once he's at the counter, mostly because he already knew exactly what to ask for instead of describing the problem vaguely and hoping the staff would figure it out.

Bilal is an illustrative example, not a documented case, but the sequence — check, identify the operator, visit with the original CNIC, ask by name for disowning, get a reference, re-check — is the actual mechanism behind every successful removal.

Confirming It Actually Worked

Don't assume the visit alone finished the job. Text your CNIC to 668 again roughly 48 hours later, or check the cnic.sims.pk portal. If the number is still showing after a few days, follow up with the same franchise using your reference number before assuming something went wrong — some updates take a little longer to fully reflect across PTA's national database than at the franchise's own local system.

If it's genuinely stuck after a reasonable wait, that's exactly the situation the PTA complaint escalation path above is for. Don't repeat the same franchise visit expecting a different result; escalate instead.

When Disowning Alone Isn't Enough

Disowning removes the SIM from your identity. It does not undo anything that was already done with it. If that unauthorised number was used to receive an OTP that authorised a transaction, take out a loan, or harass someone, the disowning process closes one door while leaving the actual incident completely unaddressed on the criminal side.

If money moved, an account was opened, or you're dealing with anything beyond the SIM itself sitting unused, read through our PTA vs NCCIA reporting guide for the criminal-side process, and our OTP fraud guide if a one-time code was involved in how the fraud actually happened. Anyone dealing with an active SIM swap in progress right now should go straight to our SIM swap fraud guide, which has a first-hour response plan rather than a general overview. And if you want the legal grounding for why any of this counts as an offence in the first place, our PECA 2016 explained guide breaks down the relevant sections.

Claims I Couldn't Verify

Where a specific fee, timeline, or age threshold wasn't confirmed directly on PTA's own published materials, I've marked it "reported" rather than official. These figures are the kind that get updated without much fanfare, so confirm the current fee and timeline directly with your operator's franchise, or through pta.gov.pk, before your visit.

Disowning An Unauthorised SIM: FAQs

Can I disown a SIM online without visiting a franchise?

No. Disowning requires a live biometric fingerprint match against your CNIC, which can only be done in person at the operator's franchise. There's no self-service online tool that removes a SIM from your CNIC directly.

Does disowning a fraudulent SIM cost anything?

No. If the SIM was never authorised by you, disowning it as fraudulent is reported to be free at any franchise, regardless of how long it's been active.

What if the franchise says the SIM can't be disowned yet because it's too new?

PTA's reported 365-day rule sets a minimum age before formal disowning or transfer. If the SIM is fraudulent and younger than that, you can still have it flagged and restricted through the franchise or a PTA complaint while the formal disowning window is pending.

Will disowning a fraudulent SIM affect my own numbers?

No. The process targets only the specific SIM you identify as unauthorised. Your legitimate numbers stay untouched, and you confirm exactly which SIM to remove with the franchise staff.

How do I know which operator an unfamiliar number belongs to?

SMS the 11-digit number to 76367, and the reply names its current network. This matters especially after porting, when a number's original prefix no longer reflects its actual operator.

What if a franchise refuses to process my disowning request?

Note the franchise name, location, date, and staff details, then file a complaint at complaint.pta.gov.pk or call 0800-55055. PTA has previously taken enforcement action against operators for franchise-level non-cooperation.

How long does it take for the SIM to actually disappear from my record?

Franchise-level action is usually logged quickly, but sources differ on exactly how fast PTA's national database fully reflects it — anywhere from about 48 hours to a few weeks depending on the case. Re-check via 668 after a couple of days, and follow up with your reference number if it's still showing.

Is disowning the same as reporting fraud to the police or NCCIA?

No. Disowning only removes the SIM from your identity. If the SIM was actually used to commit fraud, identity theft, or financial loss, you separately need to report that to NCCIA, and possibly file a police FIR, since disowning alone doesn't investigate the crime.

How many SIMs am I allowed to have on one CNIC?

Up to 8 total, made up of 5 voice connections and 3 data-only connections, combined across all operators. Going over triggers restrictions until the excess is disowned.

What should I bring to the franchise?

Your original CNIC (not a copy), the unauthorised number written down, and knowledge of which operator it belongs to. If it's part of a wider fraud case, bring any FIR or complaint reference too.
