Govt Acts Against 183,000 Telecom Resources, Blacklists 263 Senders

The Indian government has taken action against 183,000 telecom resources and blacklisted 263 senders in the first quarter of the current fiscal year (Q1 FY27) as part of its efforts to curb Unsolicited Commercial Communications (UCC).

This enforcement action targeted multiple layers, including outgoing barring, long-term disconnection, sender blacklisting across all operators, and SMS header blocking, to prevent repeat violations. According to the Ministry of Communications, the total number of UCC complaints stood at 1.085 million, which is approximately 1.5 complaints per million calls out of the 730.82 billion total calls originated in the telecom network in the country during Q1 FY27.

The TRAI DND App accounted for 89% of all UCC complaints received by the Access Providers. Notably, AI-based spam detection flagged 24.43 billion suspected spam calls and SMSs, enabling consumers to exercise caution when receiving such communications.

Over 243,000 warning notifications were issued to suspected senders within one week of the commencement of sending warning notifications. Consumers can use the TRAI DND App, their telecom service provider's app or website, or call/send SMS to 1909 to register and modify their Do Not Disturb (DND) preferences for blocking or receiving promotional communications from senders.

More than 1.12 billion subscribers have not registered any preference and are therefore accessible for all commercial communications from registered telemarketers and senders. Consumers who wish to control commercial communications can register their preferences on the DND registry.

Registered DND preferences enabled the blocking of about 1.48 billion promotional calls and 7.30 billion promotional SMSs, demonstrating effective consumer preference enforcement. About 13.16 billion promotional calls and 248.06 billion commercial SMS were routed through registered communication channels.

The Telecom Regulatory Authority of India (TRAI) introduced the designated 140 series for promotional calls to ensure that such calls originate from a dedicated numbering series, enabling consumers to easily identify and manage such calls. The calls originating from 140 series numbers are pre-verified against the preferences of the customers before delivery.

The 1600 series was introduced for service and transactional calls by entities in the Banking, Financial services, and Insurance sector, and for Government-to-citizen communication.

The government's efforts to curb UCC are significant, and the enforcement actions taken in Q1 FY27 demonstrate the commitment to protecting consumers from unwanted commercial communications. The use of AI-based spam detection and the introduction of dedicated numbering series for promotional calls are notable steps in this direction.

In conclusion, the government's actions against UCC are crucial for protecting consumers and promoting a safe and secure telecom environment. The enforcement actions taken in Q1 FY27 are a positive step towards achieving this goal, and it is essential to continue monitoring and addressing UCC complaints to ensure that consumers' preferences are respected.
