TRAI Initiates Rollout of 1601-Series Numbering System to Verify Business Calls
This dedicated series, allocated by the Department of Telecommunications (DoT), helps citizens easily distinguish legitimate operational calls from fraudulent attempts.
The 1601-series is strictly meant for non-BFSI commercial entities and government bodies, while explicitly prohibiting any promotional or marketing communications.
Exam Significance: Standardized series numbering is a key regulatory step to strengthen consumer cyber-safety and curb unwanted telemarketing spam.
