❖ Performance of the individual Telecom Service Providers (TSPs) in controlling UCC/Spam as Originating Access Provider (OAP) is enclosed as Annexure A, and their performance as Terminating Access Provider (TAP) is enclosed as Annexure B.

Consumer participation through the TRAI DND App continued to play a critical role in strengthening enforcement against spam communications. The App is a tool for consumers to register and modify their preferences for blocking or receiving promotional communications with ease, and is a convenient option to report UCC. As UCC complaints provide the basis for identification of the spammers and taking action against them, TRAI has been taking up various consumer awareness campaigns to encourage customers to report UCC.

Key Insights:

❖ The TRAI DND App accounts for 92.9% of all UCC complaints received by the Access Providers.

❖ During the quarter Jul’26 to Sep’26, media campaigns to educate customers about TRAI DND app were undertaken through 132 FM Channels, 15 AIR FM Channels, 23 Private TV Channels, 2 DD Channels and 97 News Papers.

❖ TRAI organized the ‘TRAI DND Reel Challenge’ on the MyGov Portal from June 2026 to August 2026 to create awareness about reporting spam calls and unwanted commercial communications through the TRAI DND App.

❖ TRAI also conducted awareness campaigns across social media platforms about the TRAI DND App, and to encourage consumers to report spam. One of the digital campaigns garnered more than 24.8 million impressions.

❖ A total of 322 Consumer Awareness Programmes were conducted physically by TRAI, Consumer Advocacy Groups registered with TRAI, and the service providers across the country during this quarter, leading to direct physical interaction with around 31 thousand participants.

❖ SMS Campaigns were also undertaken and more than 3 billion SMS were sent to the customers from July to September,2026, for making them aware about the TRAI DND App.

Consumers can use the TRAI DND App, their telecom service provider’s App/ Website, or call/ send SMS to 1909 to register and modify their Do Not Disturb (DND) preferences for blocking or receiving promotional communications from the senders from any or all the sectors.

Key Insights:

❖ More than 1.12 billion subscribers have not registered any preference, and, hence, are accessible for all commercial communications from registered telemarketers and senders. The consumers desirous of controlling commercial communications can register their preferences on DND registry.

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 designated series enables the consumer to exercise the choice of accepting or declining the call.

The 1600 series was introduced for service and transactional calls by the entities in Banking, Financial services & Insurance sector, and for Government to citizen communication. This designated series provides trusted calling numbers for such important communications.

Further, for service and transactional calls by the Utilities, and the entities in logistics and delivery sectors, TRAI introduced 1601 series on 10^th August, 2026.

Together, these dedicated numbering series improve transparency, consumer trust, and the effectiveness of regulatory enforcement against spam and fraudulent communications.

Key Insights:

❖ Registered DND preferences enabled blocking of about 1.70 billion promotional calls and 11.09 billion promotional SMSs, demonstrating effective consumer preference enforcement.

❖ 15.27 billion promotional calls and 660.71 billion commercial SMS were routed through registered communication channels.

In order to alert the consumers from suspected spam calls and SMS from entities using normal 10-digit numbers that bypass the regulated system, AI-based systems have been deployed by the Telecom Service providers (TSPs) to flag such suspected spam on the basis of calling pattern analysis. Further, the telecom service providers have started sending warning notifications to entities suspected with high probability of sending such spam. An entity could be using multiple numbers for sending spam. These notifications warn the suspected senders of regulatory action so as to refrain from sending further spam.  

Key Insights:

❖ AI-based spam detection flagged 19.9 billion suspected spam calls/SMS, enabling consumers to exercise choice of either ignoring such communication or picking such communications with caution.

❖ Over 4.59 million warning notifications were issued to the suspected senders during the quarter.

❖ Performance of the individual Telecom Service Providers (TSPs) in controlling UCC/Spam by using AI-based preventive measures is enclosed as Annexure-C.
