The quarterly report detailing actions taken against Unsolicited Commercial Communications (UCC) for Q1 FY27 indicated that commercial SMS traffic from registered senders and telemarketers totaled approximately 248.06 billion. Of these, 7.30 billion promotional SMS were blocked after checking against registered DND preferences.
The TRAI report further revealed that 1.15 billion calls came from 1600 dedicated series numbers during Q1 FY 2026-27.
TRAI established the 140 series specifically for promotional calls, allowing such calls to come from a distinct numbering series, which aids consumers in easily identifying and managing them.
This designated series gives consumers the option to accept or reject calls, as stated by TRAI.
Additionally, the 1600 series was specifically introduced for service and transactional calls within the Banking, Financial Services, and Insurance sectors, as well as for communications from Government to citizens.
”Registered DND preferences contributed to the blocking of approximately 1.48 billion promotional calls and 7.30 billion promotional SMS, showcasing the effectiveness of enforcing consumer choices,” stated the Telecom Regulatory Authority of India (TRAI) report.
In total, nearly 13.16 billion promotional calls and 248.06 billion commercial SMS were sent through registered communication channels. TRAI reported that AI-driven spam detection flagged 24.43 billion suspected spam calls/SMSs, allowing consumers to choose whether to ignore these communications or proceed with caution. During the first week of implementing these notifications, over 243,000 warning notices were sent to suspected senders.
In total, measures were taken against 183,000 telecom resources and 263 senders were blacklisted in Q1 FY 2026-27.
”Enforcement efforts targeted multiple layers, including outgoing barring, long-term disconnection, sender blacklisting across all operators, and SMS header blocking, to address repeat violations,” stated TRAI.
Out of the 730.82 billion total calls made in the telecom network during the April to June period this year, UCC complaints reached 1.085 million, equivalent to nearly 1.5 complaints per million calls, according to TRAI.
