The Pakistan Telecommunication Authority (PTA) has blocked 176,000 WhatsApp accounts that were registered on recycled mobile numbers. The action was taken together with Meta, the company that owns WhatsApp, after complaints that these numbers were being used to commit fraud.
Recycled numbers are mobile numbers that were once used by one person, then cancelled or left unused, and later given to a new subscriber. The problem is that WhatsApp accounts linked to the old number often stay active even after the SIM is cancelled. Fraudsters can then misuse those accounts, and the new owner of the number can also face trouble. PTA moved to shut down these accounts in phases to protect subscribers.
Why Recycled Numbers Are a Fraud Risk
When a mobile number is cancelled or abandoned, it does not disappear. After a waiting period, the telecom operator puts it back into circulation and gives it to a new customer. But the WhatsApp account that was registered on that number may still be working.
That creates two risks. First, someone who still controls the old WhatsApp account can keep using a number that now belongs to another person. Second, the new owner may receive messages, calls, or one-time passwords meant for the previous owner. In the worst cases, fraudsters use these accounts to run scams, impersonate people, and trick victims into sending money.
PTA officials said complaints about this exact problem reached the regulator, and that is what led to the action against the 176,000 accounts.
What PTA and Meta Agreed to Do
PTA has shared around 10 million recycled mobile numbers with Meta so the company can check which WhatsApp accounts are still registered on them and block those accounts. This is not a one-time exercise. Under a new permanent arrangement, PTA will share details of 5,000 recycled numbers with Meta every month, and the accounts linked to those numbers will be identified and blocked in phases.
Blocking in phases matters because the numbers involved are large. Telecom operators in Pakistan currently hold around 16 million recycled mobile numbers in their pools. Checking and clearing them all at once is not practical, so the monthly flow of 5,000 numbers keeps the process going without interruption.
PTA officials also said that Meta resolved 82 percent of the complaints the regulator forwarded during the previous year. That figure points to a working relationship between the regulator and the platform, and it is the reason PTA is using the same channel for the recycled-number problem.
The Scale of the Problem
The numbers behind this story show why the regulator is treating recycled SIMs as a serious issue:
- 176,000 WhatsApp accounts blocked so far
- Around 10 million recycled numbers already shared with Meta
- Around 16 million recycled numbers held by telecom operators
- 5,000 numbers to be shared with Meta every month from now on
- 82% of PTA complaints resolved by Meta last year
The 10 million numbers already shared cover most of the recycled pool, but the monthly updates are what will keep the system clean as more numbers are cancelled and reissued over time.
What This Means for WhatsApp Users
This action targets accounts linked to cancelled and recycled numbers. It is not a general ban on WhatsApp users, and ordinary users who own their number and SIM should not be affected.
Still, there are a few practical things users should keep in mind:
- If you get a new SIM, check WhatsApp. When you receive a new number, open WhatsApp and make sure the account on that number is yours. If an old account is still linked to the number, re-register it with your own details.
- Do not ignore strange messages. If you start receiving messages or verification codes meant for someone else, do not share them with anyone. A code sent to your number can be used to take over an account.
- Report fraud to PTA. If a WhatsApp account linked to your number is misused, you can complain through PTA’s complaint system. The 82 percent resolution figure shows that complaints forwarded by PTA do get action from Meta.
- Keep your SIM active. Numbers that stay unused for a long time are the ones that get recycled. If a number matters to you, keep the SIM active and topped up.
A Step Towards Safer Numbers
The PTA and Meta arrangement is a small but useful piece of Pakistan’s fight against online fraud. It does not solve every scam on WhatsApp, but it closes one clear gap: accounts that should have died with a cancelled SIM will now be shut down in an organised way.
The monthly sharing of 5,000 numbers means the work will continue quietly in the background. For users, the message is simple: your phone number is tied to your digital identity, so treat a recycled number with care, and check your WhatsApp account whenever you change your SIM.
FAQs
Why did PTA block 176,000 WhatsApp accounts?
Because those accounts were registered on recycled mobile numbers — numbers that were cancelled by their original owners and later reissued. Fraudsters were misusing such accounts, so PTA asked Meta to block them.
Is WhatsApp banned in Pakistan?
No. This action only affects specific accounts linked to recycled or cancelled numbers. Ordinary WhatsApp users are not affected.
What is a recycled mobile number?
It is a number that was once used by one subscriber, then cancelled or left unused, and later given to a new subscriber by the telecom operator.
How will PTA and Meta continue this work?
PTA will share 5,000 recycled numbers with Meta every month, and Meta will identify and block the WhatsApp accounts linked to them in phases.
How many recycled numbers are there in Pakistan?
Telecom operators hold around 16 million recycled numbers. PTA has already shared details of about 10 million of them with Meta.
What should I do if I get a new SIM?
Open WhatsApp and confirm the account on your number is yours. If you receive verification codes or messages meant for someone else, do not share them, and report misuse to PTA.
Conclusion
PTA and Meta have blocked 176,000 WhatsApp accounts linked to recycled mobile numbers, and a permanent monthly system will keep clearing more. With around 16 million recycled numbers in circulation, the risk is real, but the phased blocking should reduce fraud linked to old numbers. Users should stay alert when they get a new SIM, check that their WhatsApp account is truly theirs, and report any misuse to PTA.
