The primary authority responsible for controlling SMS spam in India is the <strong>Telecom Regulatory Authority of India (TRAI)<\/strong>.<\/p>\n<p>Over the years, TRAI has introduced several rules and technologies\u2014such as <strong>DLT registration, consent management, and message classification<\/strong>\u2014to protect mobile users from unsolicited commercial messages. Businesses that send SMS marketing campaigns must follow these laws to avoid penalties or service suspension.<\/p>\n<hr \/>\n<h2>Main Law Governing SMS Spam in India<\/h2>\n<p>The main regulation controlling spam messages is the <strong>Telecom Commercial Communication Customer Preference Regulations (TCCCPR)<\/strong> introduced by TRAI. It was created to reduce unwanted marketing calls and SMS and to give consumers control over what communications they receive. (<a title=\"The Telecom Commercial Communication Customer Preference Regulations, 2010\" href=\"https:\/\/en.wikipedia.org\/wiki\/The_Telecom_Commercial_Communication_Customer_Preference_Regulations%2C_2010?utm_source=chatgpt.com\">Wikipedia<\/a>)<\/p>\n<p>Under this regulation:<\/p>\n<ul>\n<li>Customers can <strong>block promotional messages<\/strong> completely.<\/li>\n<li>Businesses must follow strict rules when sending marketing SMS.<\/li>\n<li>Telecom operators must monitor and take action against spam senders.<\/li>\n<\/ul>\n<p>These rules apply to all organizations using <strong>bulk SMS, promotional SMS, or transactional messaging<\/strong>.<\/p>\n<hr \/>\n<h2>Key SMS Spam Rules Businesses Must Follow<\/h2>\n<h3>1. DLT Registration is Mandatory<\/h3>\n<p>Any company that wants to send bulk SMS in India must register on the <strong>DLT (Distributed Ledger Technology) platform<\/strong> provided by telecom operators.<\/p>\n<p>DLT registration requires:<\/p>\n<ul>\n<li>Business (Principal Entity) registration<\/li>\n<li>Sender ID (Header) approval<\/li>\n<li>Message template approval<\/li>\n<li>Consent registration<\/li>\n<\/ul>\n<p>Without DLT approval, telecom operators will <strong>block SMS campaigns automatically<\/strong>. (<a title=\"SMS Regulations\" href=\"https:\/\/docs.clevertap.com\/docs\/sms-regulations?utm_source=chatgpt.com\">CleverTap User Docs<\/a>)<\/p>\n<hr \/>\n<h3>2. Customer Consent is Required<\/h3>\n<p>Businesses cannot send promotional SMS without <strong>explicit customer consent<\/strong>.<\/p>\n<p>This means:<\/p>\n<ul>\n<li>Customers must opt-in to receive messages.<\/li>\n<li>Consent must be recorded and registered on the DLT system.<\/li>\n<\/ul>\n<p>TRAI requires organizations to <strong>collect and store customer consent before sending commercial communication<\/strong>. (<a title=\"Advice to Senders | Telecom Regulatory Authority of India\" href=\"https:\/\/trai.gov.in\/advice-to-senders?utm_source=chatgpt.com\">Telecom Regulatory Authority of India<\/a>)<\/p>\n<hr \/>\n<h3>3. Do Not Disturb (DND) Registry<\/h3>\n<p>India has a <strong>Do Not Disturb (DND) registry<\/strong> that allows customers to block promotional messages.<\/p>\n<p>Key points:<\/p>\n<ul>\n<li>Users can activate DND by calling or messaging <strong>1909<\/strong>.<\/li>\n<li>Businesses must check DND lists before sending promotional SMS.<\/li>\n<li>Sending messages to DND numbers can lead to penalties.<\/li>\n<\/ul>\n<p>The registry is maintained through the <strong>National Customer Preference Register (NCPR)<\/strong>. (<a title=\"Do Not Disturb Registry\" href=\"https:\/\/en.wikipedia.org\/wiki\/Do_Not_Disturb_Registry?utm_source=chatgpt.com\">Wikipedia<\/a>)<\/p>\n<hr \/>\n<h3>4. Message Template Approval<\/h3>\n<p>Businesses must pre-register their SMS content templates on the DLT system.<\/p>\n<p>There are different categories:<\/p>\n<ul>\n<li>Promotional SMS<\/li>\n<li>Transactional SMS<\/li>\n<li>Service SMS<\/li>\n<li>Government messages<\/li>\n<\/ul>\n<p>Only <strong>approved templates can be sent<\/strong>, and unregistered messages may be blocked.<\/p>\n<hr \/>\n<h3>5. SMS Category Identification (New TRAI System)<\/h3>\n<p>Recent updates require SMS headers to include <strong>classification suffixes<\/strong> so users know the type of message they are receiving.<\/p>\n<p>Examples include:<\/p>\n<ul>\n<li><strong>P<\/strong> \u2013 Promotional messages<\/li>\n<li><strong>S<\/strong> \u2013 Service messages<\/li>\n<li><strong>T<\/strong> \u2013 Transactional alerts (banking, OTP)<\/li>\n<li><strong>G<\/strong> \u2013 Government messages<\/li>\n<\/ul>\n<p>This system helps users easily identify promotional or spam messages.
