DLT Registration Guide for Businesses (India)

In India, businesses that want to send Bulk SMS, OTP alerts, promotional campaigns, or transactional messages must complete DLT (Distributed Ledger Technology) registration. This system was introduced by the Telecom Regulatory Authority of India (TRAI) to prevent spam SMS and protect users from unsolicited communications.

If your business plans to run SMS marketing campaigns or send service notifications, DLT registration is mandatory. Without DLT approval, telecom operators will block your SMS traffic.

Businesses that want reliable messaging solutions can integrate SMS and messaging services through:

What is DLT Registration?

DLT stands for Distributed Ledger Technology, a blockchain-based system introduced by telecom operators to record and monitor SMS communications.

The DLT platform ensures:

• Transparency in business messaging
• Prevention of spam and fraud SMS
• Authentication of senders
• Protection of customer data

Businesses must register their company and messaging templates on approved DLT platforms operated by telecom providers.

Why DLT Registration is Important

DLT registration ensures that only verified businesses can send SMS campaigns. This helps create a secure communication ecosystem.

Key benefits include:

• Legal compliance with TRAI regulations
• Higher SMS delivery rates
• Protection from spam complaints
• Secure communication with customers
• Improved brand credibility

Companies that complete DLT registration can run promotional campaigns, OTP services, and transactional alerts without interruption.

Documents Required for DLT Registration

Businesses must submit certain documents during the registration process.

Common requirements include:

• Business PAN Card
• GST Certificate
• Business Registration Proof
• Authorized Signatory ID
• Company Address Proof
• Website or business details

After submitting these documents, the telecom operator verifies the business identity before granting approval.

Step-by-Step DLT Registration Process

Step 1: Choose a DLT Operator

Businesses must register on a telecom operator’s DLT portal such as:

Airtel DLT
Vodafone Idea DLT
Jio DLT
BSNL DLT

You only need to register once, and the registration will be recognized across operators.

Step 2: Create a Business Account

• Business name
• Company address
• Authorized signatory details
• Contact information

Once submitted, you will receive login credentials.

Step 3: Upload Business Documents

Upload required verification documents such as:

• PAN card
• GST certificate
• Company registration proof

The telecom operator will verify your business identity.

Step 4: Register Sender ID (Header)

A Sender ID (also called SMS Header) represents your brand name in SMS messages.

Example:

BUDINF
ADINFT
SHOPNG

There are two types of headers:

Promotional Header – Used for marketing campaigns
Transactional Header – Used for OTP and alerts

Once approved, this header will appear as the sender name in your SMS.

Step 5: Submit SMS Templates

Businesses must register all SMS templates before sending messages.

Examples include:

• OTP messages
• Order confirmation alerts
• Promotional campaigns
• Appointment reminders

Each template must be approved by the DLT system.

Step 6: Start Sending SMS Campaigns

After approval of:

• Business registration
• Sender ID
• SMS templates

You can start sending SMS using a messaging platform.

Transactional SMS

Important alerts related to customer transactions.

Example:

Common Mistakes to Avoid During DLT Registration

Many businesses face SMS delivery issues due to incorrect DLT setup.

Avoid these mistakes:

• Using unregistered sender IDs
• Sending messages without approved templates
• Mismatch between SMS content and template
• Ignoring customer consent rules
• Not updating templates when campaigns change

Proper DLT compliance ensures smooth SMS delivery and avoids regulatory penalties.
