What is DLT Registration? How important it is for SMS services in India?

Distributed Ledger Technology

DLT stands for “Distributed Ledger Technology.” It is a digital system that records and stores transactions or data across multiple locations in a decentralized and secure manner. DLT provides transparency, security, and immutability to data, making it suitable for various applications, including financial transactions, supply chain management, and more.

In the context of SMS services in India, DLT registration refers to the process of registering and authenticating entities (such as businesses, telemarketers, and senders) that wish to send commercial messages to mobile phone users. This registration is mandated by the Telecom Regulatory Authority of India (TRAI) to regulate and curb the problem of unsolicited and spam SMS messages, also known as Unsolicited Commercial Communication (UCC).

Here’s an overview of DLT registration for SMS:


DLT registration for SMS aims to curb spam, fraudulent, and unsolicited SMS messages. It requires businesses and organizations that send commercial and promotional messages to register on the DLT platform before sending SMS to recipients.

Steps for DLT Registration:

The exact process may vary depending on the country and the specific DLT platform being used. However, the general steps for DLT registration typically include:

Account Creation: Register on the DLT platform using your organization’s details. This might involve providing company information, contact details, and other necessary documentation.

Entity Verification: Verify your organization’s identity through documentation such as PAN (Permanent Account Number) or GST (Goods and Services Tax) certificates.

Header and Template Registration: Register sender IDs (headers) and message templates that you intend to use for your SMS campaigns. These need to be pre-approved by the regulatory authorities to ensure they comply with guidelines.

Consent Management: Manage recipient consent and preferences through the DLT platform. You’ll need explicit consent from recipients to send them commercial messages.

Scrubbing and Cleaning Data: Scrub your existing SMS database against the DLT platform’s database to ensure that you’re not sending messages to recipients who have opted out or registered on DLT themselves.

Reconciliation: Regularly reconcile your SMS traffic with the DLT platform’s reports to ensure accuracy and compliance.

Benefits of DLT Registration:

DLT registration offers several benefits, including:

  1. Enhanced transparency and accountability in SMS communications.
  2. Reduction of spam and unsolicited messages, leading to improved customer experiences.
  3. Strengthened regulatory compliance and avoidance of penalties.
  4. Improved data quality through consent management and scrubbing processes.

Impact on SMS Marketing:

DLT registration can impact how businesses conduct SMS marketing. It ensures that SMS recipients are only receiving messages they’ve consented to, thereby increasing the effectiveness of SMS campaigns and maintaining customer trust.

Here's why DLT registration is required for SMS services in India:

Combating Spam and Unwanted Messages:

The prevalence of spam and unwanted promotional messages has been a significant issue in India, leading to inconvenience for mobile phone users. DLT registration aims to curb this problem by ensuring that only authorized and registered entities can send commercial messages.

Enhanced User Experience:

DLT registration ensures that users receive only relevant and legitimate commercial messages. This enhances the overall user experience and reduces the annoyance caused by unsolicited messages.

Regulatory Compliance:

TRAI introduced DLT registration as part of its efforts to regulate and streamline commercial communications. It establishes a framework for compliance with rules and guidelines related to messaging.

Transparency and Accountability:

DLT provides a transparent and accountable system where the sender’s identity is verified, and their messaging activities are monitored. This helps in tracking and penalizing entities that engage in spamming or violation of regulations.

Opt-In and Opt-Out Mechanisms:

DLT registration includes mechanisms for users to opt in or opt out of receiving commercial messages. Users have the control to choose the types of messages they want to receive.

Real-Time Reporting and Monitoring:

DLT platforms offer real-time reporting and monitoring of message delivery, ensuring greater transparency and accountability for both senders and telecom operators.

Reduction of Network Congestion:

By curbing the volume of spam messages, DLT registration contributes to a reduction in network congestion, leading to improved network performance.

It’s important for businesses and organizations to complete the DLT registration process with authorized DLT providers and ensure compliance with the regulations set by TRAI. Failure to do so could result in penalties and restrictions on sending commercial messages. Overall, DLT registration is a significant step toward creating a more organized and legitimate environment for commercial messaging in India.
