Dot Fri System Blacklist 4 Lakh Sim Cards Fraud Numbers in Scam Activities All Details

If you also rely on the investment or job offer from an unknown number, then this news is important for you. A recent report states that the telecom department (DOT) has blacklisted SIM cards from 3 to 4 lakhs so far from a special AI-based system. All these numbers were allegedly associated with fraud and scams. For this, Dot has prepared a special financial fraud risk indicator (FRI) system, which was launched a few months ago.

Latest of ET Report According to, this FRI system of DOT has blocked 3 to 4 lakh SIM cards so far. The tool is reportedly detecting around 2,000 mobile numbers every day, which are mostly associated with jobs and investment.

A senior DOT official told Publication that as soon as a mobile number is marked as a “high risk” through FRI, the system also discovers other SIM cards associated with that number on the network. This work is done by AI-powered pattern matching. That is, not only one number, the entire network attached to it is tracked.

Due to this system, last month, UPI platforms, such as Google Pay, PhonePe and Paytm, have been able to stop a potential fraud transactions worth several crores.

In July 2025, the Reserve Bank of India (RBI) advised all banks, whether they are commercial, payment banks or cooperative banks, to integrate the FRI system in their platform. After this, the processing speed and action time have also been reduced by making some improvement in the FRI system.
