DLT Registration, or Distributed Ledger Technology registration, is a mandatory compliance process introduced by telecom regulatory authorities in India to regulate bulk SMS services and prevent spam or fraudulent messaging. All businesses or enterprises sending promotional, transactional, or service SMS to their customers are required to register on a DLT platform approved by TRAI (Telecom Regulatory Authority of India).
DLT acts as a blockchain-based system that keeps a transparent record of all SMS communications. This process ensures that only authentic, registered senders can use telecom routes to reach customers, safeguarding the end-user from unwanted or harmful messages.
DLT registration is not optional—it’s a legal requirement. But beyond compliance, it also brings a host of benefits that enhance the credibility and deliverability of your business communication.
1. Ensures Compliance with TRAI Regulations
Since the TRAI directive came into force, DLT registration has become mandatory for all SMS and voice communication services. Without DLT approval, telecom operators block messages sent via unregistered entities. Registering ensures you are legally eligible to run bulk SMS campaigns or notifications.
2. Builds Trust and Transparency
Customers today are cautious about unsolicited messages. With DLT, every sender and template is verified and recorded, which reduces spam and increases trust in the messages received. A registered business appears more credible to the end recipient.
3. Improves SMS Delivery Rate
Once you’re DLT registered, your messages are less likely to get flagged or blocked. Telecom operators prioritize verified senders, ensuring faster and more reliable message delivery, especially for critical transactional alerts.
4. Protects Customer Privacy
DLT platforms are designed to protect consumer data by restricting access to only verified businesses. This ensures that customer contact details are not misused and helps maintain data privacy and integrity.
DLT registration may sound technical, but it’s a straightforward process with the right guidance. Here’s a step-by-step overview:
Step 1: Choose a DLT Portal
Several telecom providers in India are authorized by TRAI to facilitate DLT registration. You can choose any of the following platforms:
Jio DLT
Vodafone Idea DLT
Airtel DLT
Tata Tele DLT
You only need to register with one DLT portal—your details are shared across all platforms after verification.
Step 2: Register as a Principal Entity
Fill out your business details, including:
PAN Card
GST Certificate
Company Letterhead
Proof of Identity (Aadhar/Passport)
Email and mobile number for verification
Once verified, you will receive a unique Entity ID that identifies your business on the DLT network.
Step 3: Add Headers (Sender IDs)
Next, register your SMS headers or sender IDs (e.g., “AM-ADMBLY”). These alphanumeric headers must be unique to your business and relevant to the type of SMS (promotional or transactional).
Headers are also subject to approval and must not resemble personal mobile numbers or misleading terms.
Step 4: Register SMS Templates
Every SMS you plan to send must be pre-approved on the DLT platform. Templates are categorized into:
Transactional Messages – For OTPs, alerts, etc.
Promotional Messages – For marketing campaigns
Service Messages – For account updates, reminders, etc.
Templates must include variables (like [NAME], [AMOUNT]) and follow a standard structure. Each approved template will be linked to your header and associated with a unique Template ID.
Step 5: Link with Telemarketer/Service Provider
After your headers and templates are approved, link your DLT Entity ID to a registered telemarketer or SMS service provider (like AdMobily). This allows you to start sending messages through telecom operator routes.
