Complete DLT Registration Process: Step-by-Step Guide by AdMobily

What Is the DLT Registration Process?

The DLT (Distributed Ledger Technology) registration process is a mandatory framework introduced by TRAI to regulate and authenticate bulk SMS and voice communications. It helps businesses send messages through a secure, verified pipeline, protecting users from spam and fraud.

To deliver promotional SMS or transactional alerts, every business must complete DLT registration, register headers, and get SMS templates approved on operator platforms like Airtel, Jio, Vodafone, or BSNL.

Learn the complete DLT registration process with AdMobily. Step-by-step guide for headers, templates & compliance. Fast onboarding for bulk SMS delivery.

Why DLT Registration Matters for Your Business

    • TRAI Compliance
      No registration = No SMS delivery. TRAI blocks unregistered communications, so compliance is non-negotiable.

    • Improved Delivery Rates
      DLT-approved headers and templates ensure faster routing and higher SMS deliverability.

    • Spam-Free Customer Experience
      Messaging from verified businesses builds trust and lowers opt-out rates.

    • Audit-Ready Messaging
      Keep all communication documented and traceable through registered templates and entity IDs.

Step-by-Step Guide to the DLT Registration Process

1. Select Your Telecom Operator’s DLT Portal

Choose from approved telecom DLT platforms like:

  • Airtel DLT

  • Jio DLT

  • Vodafone-Idea DLT

  • BSNL or MTNL DLT

Tip: Select the platform used by your bulk SMS service provider for smoother integration.


2. Register Your Business as a Principal Entity

Submit:

  • PAN card

  • GST certificate

  • Business license or incorporation proof

  • Letter of Authorization

After KYC, you’ll receive a unique DLT Entity ID — your official business identity across all platforms.


3. Apply for SMS Headers (Sender ID)

Create your 6-character header (e.g., ADMBLY, ADMSMS) and submit:

  • Category: Promotional, Transactional, or Service

  • Purpose: OTPs, updates, offers, alerts

  • Proof of brand ownership

➡️ Learn how to select the right Promotional SMS Service strategy for your campaigns.


4. Register Message Templates

Submit template text like:

“Dear [NAME], your OTP is [OTP]. Valid for 5 mins. – AdMobily”

Mark it as Transactional or Promotional, include variables, and submit for approval.
Each approved template gets a Template ID, which must be used for every message sent.

Once templates are approved:

  • Integrate them with your SMPP service or other SMS API platform

  • Share your Entity ID, Header ID, and Template IDs with your provider

  • Start sending DLT-compliant messages
