Summary

TRAI introduced the '1600' number series to build consumer trust.
This series is for banks, financial, and insurance sector entities.
It helps citizens identify legitimate calls from regulated institutions.

The Telecom Regulatory Authority of India (TRAI) has initiated a significant measure by assigning the '1600' numbering series. This strategic move is designed to bolster consumer confidence and actively combat the growing menace of spam and fraudulent voice calls. The '1600' series is specifically designated for entities operating within the crucial banking, financial services, and insurance (BFSI) sectors, along with government organizations.

The Department of Telecommunications (DoT) has allocated this special numbering series to clearly differentiate official service and transactional communications. This distinction is vital for public safety and trust in telecommunications.

By enabling citizens to reliably identify legitimate calls originating from regulated financial institutions and government bodies, TRAI aims to create a more secure communication environment. This proactive step is expected to significantly curb fraudulent activities and enhance the overall integrity of voice-based interactions.
