PTA Blocks 176,000 WhatsApp Accounts in Pakistan Over Recycled SIM Fraud

By Fatima Raza | Updated: November 6, 2026

The Pakistan Telecommunication Authority (PTA), working with Meta, has blocked 176,000 WhatsApp accounts in Pakistan that were registered against recycled mobile numbers, the regulator said on Friday, November 6, 2026. The accounts were shut down after complaints that numbers reissued to new subscribers were being used for cyber fraud, and the PTA has now agreed a permanent monthly system with Meta to keep catching them. This is not a ban on WhatsApp, and it does not affect ordinary users whose accounts are registered to a number they still own. Below: how the fraud works, the numbers behind the crackdown, and what to check on your own phone today.

PTA WhatsApp Block: Key Facts

How Recycled SIM Fraud Works

When a mobile number goes unused for a long time, or a SIM is cancelled, the operator eventually puts that number back into circulation and gives it to a new customer. In Pakistan this happens on a very large scale: operators hold around 16 million recycled mobile numbers, according to PTA officials.

The trouble is that WhatsApp does not know the number has changed hands. The old owner’s account can stay registered to that number even after the original SIM has been deactivated. That creates an opening: a new subscriber who receives the recycled number can, in some cases, receive verification codes for it and take control of the account, exposing chats and contacts and enabling impersonation and fraud. PTA officials said complaints about exactly this kind of misuse prompted the regulator to take the matter up with Meta.

16 Million Recycled Numbers, 10 Million Shared With Meta

That scale explains why the PTA went to Meta rather than fixing it alone. Of the roughly 16 million recycled numbers operators hold, the PTA has shared details of around 10 million with Meta for verification and blocking of the WhatsApp accounts linked to them. The 176,000 accounts blocked so far are the first result of that exercise, and the blocking is being done in phases.

What happens next matters more. The PTA and Meta have agreed a permanent mechanism under which the regulator will share details of another 5,000 recycled numbers with Meta every month, and the accounts associated with those numbers will be identified and deactivated. That turns a one-off cleanup into a standing process. PTA officials also noted Meta resolved 82% of complaints forwarded to it last year — evidence, the PTA said, of improved coordination.

What This Means for You

For most WhatsApp users in Pakistan, nothing changes — if your account is registered to a number you currently own, this action does not touch you. Still, check three things, because the same risk applies to any account you have not updated.

First, make sure your WhatsApp is registered to a number you actually control. If you changed your number and never updated WhatsApp, your old account is still sitting on a number that may now belong to a stranger. WhatsApp has a built-in Change Number feature that moves your account, chats and groups to your new number. Keeping the registered number current matters for everything else you do on WhatsApp too — our guide to WhatsApp message scheduling and how to set it up starts from the same point, an account tied to the number you actually use.

Second, turn on two-step verification inside WhatsApp: a six-digit PIN that anyone trying to register your number on another phone would also need, closing the exact gap this fraud exploits. Third, never share a WhatsApp verification code with anyone. No bank, no government office and no WhatsApp support agent will ever ask for it. The same caution applies to messages claiming to come from the regulator itself: the PTA has previously had to warn the public about fake notifications, including a fake TikTok ban notification that the PTA publicly rejected. If a message claims your account will be blocked unless you share a code or click a link, treat it as a scam.

New subscribers deserve a special note. If you recently bought a SIM and started receiving WhatsApp messages or verification codes meant for someone else, your number was recycled — report it rather than ignoring it. The same logic applies to your bank accounts, since a phone number is now the recovery key for almost everything. And if fraud that started with a phone number has ever cost you money, you can get it back: the Banking Mohtasib ordered Rs 1.2 billion in refunds to customers over complaints.

PTA’s Busy Week: Field Checks in Islamabad and Rawalpindi

The crackdown came in the same week the PTA was checking mobile service quality on the streets of Islamabad and Rawalpindi. On Thursday, November 5, the regulator launched a special field inspection campaign, led personally by PTA Chairman Hafeez Ur Rehman, with three teams testing voice quality, call connection rates and mobile data speeds along the airport road, Srinagar Highway, the Islamabad Expressway, Murree Road and Rawal Road. The two reports of that inspection differ: Dawn reported that the PTA found mobile call quality not up to the mark in certain areas, although services were generally satisfactory in most areas inspected, while the Express Tribune said the PTA described internet services in the twin cities as excellent. The operators said ongoing 3G-to-4G and 4G-to-5G upgrades can temporarily affect quality.

What This Is Not

WhatsApp has not been banned in Pakistan, and ordinary users face no restriction. Nobody needs to stop using WhatsApp or re-register. The action targets only accounts registered against numbers that are no longer active or no longer belong to the person who registered them. A targeted cleanup, run in phases and repeated every month, removes the accounts that can be misused while leaving everyone else untouched.
