The Pakistan Telecommunication Authority (PTA) has blocked 176,000 WhatsApp accounts linked to recycled mobile phone numbers in collaboration with Meta, as part of efforts to prevent online fraud and protect mobile subscribers across the country.
According to PTA officials, the accounts were deactivated following complaints that recycled mobile numbers were being misused to carry out fraudulent activities through WhatsApp.
The action was taken at the regulator’s request, with Meta assisting in blocking the accounts associated with the affected numbers. The move aims to reduce the risks faced by people whose mobile numbers have been reassigned to new users after being disconnected from previous subscribers.
Recycled mobile numbers have become a growing concern in digital security because mobile operators may reissue inactive numbers to different customers after a certain period. However, previous owners may still have accounts linked to those numbers on messaging platforms and other online services.
This situation can create opportunities for misuse, particularly when old WhatsApp accounts remain associated with numbers that have been assigned to new subscribers.
In some cases, the new owner of a recycled number may receive messages intended for the previous subscriber or encounter account-related issues. Fraudsters can also exploit confusion surrounding ownership and account access to deceive individuals.
WhatsApp accounts are commonly used for personal communication, business transactions, customer services and financial interactions. As a result, unauthorized access or misuse can expose users to scams, identity-related problems and potential financial losses.
The PTA’s latest action highlights the importance of cooperation between telecommunications regulators and technology companies in addressing digital security threats.
By requesting the deactivation of affected accounts, the authority aims to prevent recycled mobile numbers from being used to continue fraudulent activities on the messaging platform.
The collaboration with Meta also demonstrates the role of digital platforms in responding to security concerns raised by national regulatory authorities. Managing accounts linked to recycled numbers requires coordination between mobile operators, regulators and online service providers.
Mobile subscribers can also take precautions to protect their digital accounts. Users should regularly review their account security settings, enable two-step verification on WhatsApp and avoid sharing verification codes with unknown individuals.
People who receive suspicious messages or unexpected requests for money should verify the sender’s identity before responding. They should also avoid clicking on unfamiliar links or sharing personal information through unverified accounts.
The development is particularly relevant in Pakistan, where WhatsApp is widely used for communication and commercial activities. Protecting accounts associated with mobile numbers is therefore an important part of improving online safety.
The blocking of 176,000 accounts represents a major step in addressing concerns surrounding recycled mobile numbers and digital fraud. The effectiveness of such measures will depend on continued coordination between the PTA, Meta and telecommunications companies.
