हे का महत्त्वाचे आहे
Demonstrates proactive regulatory interventions by TRAI to mitigate the prevalent issues of unsolicited commercial communication (UCC) and cyber frauds, thereby enhancing digital trust and consumer security.
सारांश
The Telecom Regulatory Authority of India (TRAI) has mandated the use of a new 1601-series for service and transactional calls by utility, courier, and logistics companies. This move, part of broader efforts to curb spam and prevent telecommunication fraud, aims to help consumers distinguish genuine service calls from promotional or fraudulent ones. The 1601-series expands upon the 1600-series already used by the government and BFSI sectors, while promotional calls remain restricted to the 140-series.
मुख्य मुद्दे
- TRAI directed the allocation of a dedicated 1601-series for transactional and service calls by entities outside the BFSI and government sectors.
- Phase 1 of the 1601-series rollout applies to utility services (water, electricity, gas) and the courier/logistics sector.
- The 1600-series is already in use for service calls by Banking, Financial Services, and Insurance (BFSI) entities and government agencies.
- The 140-series is designated exclusively for promotional calls.
- The initiative is designed to prevent fraud by helping consumers easily identify legitimate, non-promotional enterprise calls.

पूर्वपरीक्षा सापळा

What is the functional division between TRAI and TDSAT?
- TRAI mandate: Regulates telecom services, fixes tariffs, and ensures quality of service under the TRAI Act, 1997.
- TDSAT mandate: Created in 2000 to adjudicate disputes and hear appeals against TRAI directions, separating regulation from adjudication.
How is Distributed Ledger Technology (DLT) applied in Indian telecom regulation?
- Decentralized registry: DLT provides an immutable, shared database across telecom operators to register commercial senders and headers.
- Spam traceability: TRAI mandates DLT to track and verify commercial communications, preventing unauthorized telemarketers from spoofing legitimate businesses.

TRAI's mandate to use Distributed Ledger Technology (DLT) for spam control shows blockchain's utility shifting from cryptocurrencies toward mainstream regulatory compliance and preventing cyber fraud.
Digital India vs. Vishing attacks
Reserving specific number series (1600 for BFSI, 1601 for utilities) helps secure digital financial inclusion by mitigating Jamtara-style voice-phishing (vishing) attacks targeting vulnerable rural and elderly populations.
