It strengthens how telecom providers identify suspected spam, adds rules for automated business calls and updates complaint and consent processes.<\/p>\n\n\n\n<p>If your business calls or messages customers, review how you register as a sender, manage consent and customer preferences, and document the reason for each communication. Businesses using automated calls also need to declare them to their telecom provider in advance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>TRAI\u2019s 2026 Rules: What Has Changed for Businesses?<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Change<\/strong><\/td><td><strong>What it means for businesses<\/strong><\/td><\/tr><tr><td>AI-based spam detection<\/td><td>Telecom providers share information about numbers suspected of sending unsolicited commercial communication (UCC).<\/td><\/tr><tr><td>Five or more flagged numbers<\/td><td>If five or more numbers linked to one sender are flagged within 10 days, providers can investigate and take graded action.<\/td><\/tr><tr><td>Complaint threshold<\/td><td>Three or more unique complaints in 10 days can trigger action if the sender\u2019s number is also flagged by the provider\u2019s AI\/ML system.<\/td><\/tr><tr><td>Automated A2P calls<\/td><td>Declare automated calls and the numbers you will use to your telecom provider in advance.<\/td><\/tr><tr><td>A2P call charge<\/td><td>A termination charge of up to \u20b90.05 per minute may apply between telecom providers.<\/td><\/tr><tr><td>Customer inquiries<\/td><td>You may contact a customer about their inquiry for up to seven days, if it was made in writing or digitally and kept in a verifiable form.<\/td><\/tr><tr><td>Older consent records<\/td><td>Legacy consent may be recognised if it was collected through verifiable means and registered on the provider\u2019s digital platform.<\/td><\/tr><tr><td>Customer appeals<\/td><td>Customers can appeal the resolution of a UCC complaint within 15 days.<\/td><\/tr><tr><td>Misused SMS headers or templates<\/td><td>Providers must suspend a misused header or template within six hours of becoming aware of the misuse.<\/td><\/tr><tr><td>Call management apps<\/td><td>Apps cannot blanket-block, filter or spam-tag calls from designated commercial number series.<\/td><\/tr><tr><td>Other changes<\/td><td>TRAI can classify senders, prescribe terms for sender-provider agreements and require real-time digital access for VNOs.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What Do the New TRAI Rules Mean for Business Calls?<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. How Does AI-Based Spam Detection Work?<\/strong><\/h3>\n\n\n\n<p>Telecom providers use AI\/ML systems to identify numbers that may be sending UCC. The amendment requires them to share information about calling line identities (CLIs) that are likely to be used for this purpose.<\/p>\n\n\n\n<p>If five or more numbers linked to one sender are flagged within 10 days, providers can investigate. Possible steps include KYC re-verification, physical verification, barring outgoing services and disconnecting telecom resources in cases of repeated violations.<\/p>\n\n\n\n<p><a href=\"https:\/\/callerdesk.io\/blog\/why-business-number-marked-as-spam\/\">A flag can start an investigation<\/a>. The appropriate action depends on the investigation and the applicable regulations.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. When Can Three UCC Complaints Trigger Action?<\/strong><\/h3>\n\n\n\n<p>Under the earlier complaint threshold, five or more unique complaints within 10 days could trigger action against a sender. The 2026 amendment allows action to be triggered by three or more unique complaints within 10 days if the sender\u2019s number is also flagged by the provider\u2019s AI\/ML system.<\/p>\n\n\n\n<p>Businesses should keep records that show the purpose of each campaign and the basis for contacting each customer. A clear record can help explain a calling pattern if the telecom provider asks questions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. What Rules Apply to Automated A2P Calls?<\/strong><\/h3>\n\n\n\n<p>TRAI defines an<a href=\"https:\/\/callerdesk.io\/blog\/what-are-a2p-calls-trai-2026-rules-explained\/\"> Application-to-Person (A2P) call<\/a> as a voice call started by an application, software system or automated platform without a person dialling directly. This includes autodiallers, robocalls and calls using prerecorded or artificial voices.<\/p>\n\n\n\n<p>If your business uses A2P calls, declare this use to your telecom provider in advance and provide the numbers that will be used. Calls made without the required declaration may be treated as UCC.<\/p>\n\n\n\n<p>The amendment also allows a termination charge of up to \u20b90.05 per minute between the terminating and originating telecom providers. Calls made through number series designated by TRAI for regulated commercial calls, and TRAI-authorised calls, are exempt from this charge. TRAI describes this as an inter-provider charge; it does not say that every business will be billed for it directly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. How Long Can You Follow Up on a Customer Inquiry?<\/strong><\/h3>\n\n\n\n<p>You may send commercial communication based on a customer\u2019s inquiry for up to<a href=\"https:\/\/callerdesk.io\/blog\/7-day-customer-inquiry-rule\/\"> seven days from the date of that inquiry<\/a>. The inquiry must be made in writing or through digital means, and your business must keep it in a verifiable form.<\/p>\n\n\n\n<p>For example, keep the date and record of a website form, email, app request or chat. A name and phone number in a spreadsheet, by itself, does not show that the person made an inquiry.<\/p>\n\n\n\n<p>This is a limited follow-up period. It is not permission to use an old lead list for general promotions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5. Can Businesses Use Older Consent Records?<\/strong><\/h3>\n\n\n\n<p>The amendment allows certain legacy consent records to be recognised. To qualify, consent must have been collected through verifiable means and later registered on the telecom provider\u2019s digital platform.<\/p>\n\n\n\n<p>An old customer database, by itself, does not prove consent. Keep the record showing how and when consent was collected, and ask your provider about the registration process.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>6. How Can Customers Appeal a UCC Complaint?<\/strong><\/h3>\n\n\n\n<p>Customers who are unhappy with the resolution of a UCC complaint can appeal to the Appellate Authority within 15 days. TRAI says an appeal can be made through available complaint channels, including the TRAI DND app, a provider\u2019s app or portal, or by calling or texting 1909.<\/p>\n\n\n\n<p>For businesses, this is another reason to keep clear records of the communication and its purpose.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>7. What Should You Do If an SMS Header or Template Is Misused?<\/strong><\/h3>\n\n\n\n<p>If a telecom provider becomes aware that an SMS header or content template has been misused, it must suspend it within six hours and notify the concerned sender.<\/p>\n\n\n\n<p>The sender must take the required corrective steps and file a complaint with the appropriate law enforcement agency. If the misuse is attributed to a telemarketer, the amendment provides for disconnection of its telecom resources across providers for one year, along with blacklisting.<\/p>\n\n\n\n<p>Review who can access your headers and templates, including agencies and messaging partners.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>8. Can Caller ID Apps Flag 140, 1600 or 1601 Series Calls?<\/strong><\/h3>\n\n\n\n<p>Call Management Applications cannot blanket-block, filter or spam-tag calls from number series designated for commercial communication. TRAI refers to the 140xx series for regulated promotional calls and the<a href=\"https:\/\/callerdesk.io\/blog\/what-is-1600-phone-number\/\"> 1600xx<\/a> and 1601xx series for service and transactional calls.<\/p>\n\n\n\n<p>People can still block or filter calls individually on their own devices. Apps that allow users to report UCC must send those reports to the platform maintained by telecom providers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>9. What Other Changes Affect Senders, Telemarketers and VNOs?<\/strong><\/h3>\n\n\n\n<p>The amendment gives TRAI the power to classify senders based on factors such as their sector, scale of operations and the impact of suspending their telecom resources. TRAI can also prescribe essential terms for agreements between telecom providers, senders and telemarketers.<\/p>\n\n\n\n<p>Network Service Operators must provide Virtual Network Operators (VNOs) with a real-time digital interface to the DLT platform and other systems they need to meet their regulatory duties.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Is the 15-Day Outgoing Call Ban a New TRAI Rule?<\/strong><\/h2>\n\n\n\n<p>No. TRAI\u2019s 2025 Second Amendment set out the 15-day bar for a first violation. Where an investigation finds a sender responsible for a first violation,<a href=\"https:\/\/callerdesk.io\/blog\/trai-15-day-outgoing-ban-business-numbers\/\"> outgoing services across the sender\u2019s telecom resources can be barred for 15 days<\/a>. Subsequent violations can lead to disconnection across providers for one year and blacklisting.<\/p>\n\n\n\n<p>The 2026 amendment changes how suspected senders are identified and when complaint-based action can be triggered. The 15-day bar should be described as part of the earlier framework, not as a penalty newly introduced in 2026.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What Does BLOCK PROMO Mean for Businesses?<\/strong><\/h2>\n\n\n\n<p>TRAI\u2019s existing customer preference framework lists BLOCK PROMO as an option for blocking promotional communication across categories.<a href=\"https:\/\/callerdesk.io\/blog\/what-is-dnd-how-to-activate-do-not-disturb\/\"> Customers can send the text to 1909<\/a>. The preference does not block service, transactional or government communication as defined by the regulations.<\/p>\n\n\n\n<p>This is part of the existing preference framework, not one of the headline changes in TRAI\u2019s 2026 press release. Businesses should check and follow customers\u2019 registered preferences before sending promotional calls or messages.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>TRAI New Rules 2026: Key Dates and Effective Date<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Date<\/strong><\/td><td><strong>What happened<\/strong><\/td><\/tr><tr><td>27 February 2026<\/td><td>TRAI directed telecom providers to share AI\/ML intelligence about suspected UCC.<\/td><\/tr><tr><td>13 March 2026<\/td><td>TRAI released the draft amendment for consultation.<\/td><\/tr><tr><td>3 June 2026<\/td><td>TRAI held an open house discussion with stakeholders.<\/td><\/tr><tr><td>18 September 2026<\/td><td>TRAI introduced the final Third Amendment Regulations, 2026.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>TRAI lists the final amendment with a release date of 18 September 2026.
