The Reserve Bank of India (RBI) has stepped up efforts to tackle cyber fraud and protect banking customers by mandating the adoption of TRAI’s Mobile Number Revocation List (MNRL) technology. Banks and other regulated entities must integrate this advanced system into their operations by March 31, 2025, to enhance fraud prevention measures.

Strengthening Digital Security: Why MNRL Technology is Crucial

The proliferation of digital transactions has improved convenience but also increased the risk of cyber fraud. According to RBI’s recent notification, mobile numbers, widely used for authentication, verification, and receiving sensitive payment communication like OTPs and transaction alerts, have become prime targets for cybercriminals.

TRAI’s MNRL, maintained on the Digital Intelligence Platform (DIP), is a comprehensive list of revoked or deactivated mobile numbers. These numbers may have been:

• Registered with fake or forged documents.
• Linked to cybercrimes or financial fraud.
• Disconnected due to inactivity or fraud detection by telecom providers.
• Reported for misuse or failed re-verification checks.

By utilizing MNRL, banks can ensure their customer databases remain updated and secure, mitigating the risks associated with fraud and unauthorized transactions.

RBI’s Directives for Fraud Prevention

To address potential risks, RBI has outlined several steps for banks and regulated entities:

1. Utilize MNRL Technology: Banks must integrate TRAI’s MNRL into their systems to monitor and cleanse their databases, ensuring that revoked mobile numbers are no longer linked to active bank accounts.
2. Verify Customer Care Details: Provide verified customer care numbers to the Department of Telecommunications (DoT) for publication on the “Sanchar Saathi” portal.
3. Special Numbering for Communication:
   • Use the ‘1600xx’ series for transactional or service calls once operational.
   • Utilize the ‘140xx’ series for promotional calls.
   • Follow TRAI’s guidelines on commercial communication via voice calls and SMS.
4. Awareness Campaigns: Conduct awareness initiatives through SMS, emails, and regional languages to educate customers about these security measures.

These measures aim to prevent the misuse of mobile numbers in cyber frauds such as money mule schemes, where fraudulent transactions are conducted using accounts linked to inactive or deactivated numbers.

How MNRL Protects Consumers

MNRL technology acts as a safeguard against cyber fraud by ensuring that banks verify the status of mobile numbers linked to customer accounts. This prevents the exploitation of revoked or inactive numbers for illicit financial activities.

Anis Ahmed, Chair of the MENA Chapter of the Association of Certified Financial Crime Specialists, highlights that cybercriminals often rely on money mules to transfer stolen funds. These mules use fraudulent or deactivated mobile numbers to avoid detection. Integrating MNRL technology will enable banks to identify and prevent such fraudulent transactions, enhancing consumer safety.

What This Means for Customers

For Indian banking customers, this initiative promises stronger digital security and reduced chances of falling victim to cyber fraud. With MNRL in place, banks can ensure that their systems are resilient against fraudulent activities, safeguarding customer trust in the digital banking ecosystem.
