This article will provide you with expert advice to help you navigate the DLT registration process and share some tips to do the same successfully.  

Understanding DLT

DLT, or Distributed Ledger Technology, is an innovative technology that allows data to be stored across multiple computers, ensuring transparency and security. In the context of sending bulk SMS in India, businesses must register with a DLT platform to ensure secure and efficient communication.

Why DLT Registration is Crucial?

DLT registration is a critical step for businesses that wish to send bulk SMS messages to their customers. This is because the DLT system validates the business's identity, ensuring that only legitimate businesses can send SMS messages using SMS API providers. This helps to protect consumers from fraudulent messages and enhances the credibility of the business.

There are use cases like authentication using SMS where businesses can leverage SMS providers like Message Central and get started with sending OTP SMS without any DLT registration.  

Essential Tips for Successful DLT Registration

The DLT registration process involves a series of steps, including verifying the business's identity, selecting the appropriate sender ID, and creating compliant content templates. It's important to note that the DLT system can reject the registration if any step is not completed correctly. Therefore, it's crucial to understand each step thoroughly and to follow the best practices.

Below, we share some essential tips that can help you register your business on the DLT platform successfully.  

1. Verifying Documents Before Registration

Before starting your DLT registration, make sure to verify and validate all required documents. This will ensure that you only upload valid documents, thus preventing rejection of your registration. The documents needed for DLT registration typically include the company's PAN card, GST certificate, letter of authorization, and proof of address.

2. Understanding the Importance of Unique IDs

A unique ID is essential for ensuring the security of your business. The DLT system checks the business name during registration, and only approves unique, registered business names. This is to prevent any potential misuse of the business name during SMS campaigns.  

3. Matching Sender ID and Company Name

Your sender ID (also known as the header or mask) must match your company name. If they do not match, the DLT system may reject your registration. Therefore, if the sender ID and the company name are not related, you should attach a relationship document as proof of identity.

4. Using Compliant Content Templates

When creating your content templates, ensure they adhere to DLT template rules and best practices. Using the right brand name and variables in your content template will increase the chances of successful registration. Templates that do not comply with these requirements may be rejected by the DLT system. You can also refer to our guide on various DLT content templates.

5. Selecting the Right Template for Your Business

Choosing the right template for your business is crucial as it sets the tone for all your future SMS campaigns. You should choose an appropriate name for your template that denotes the purpose of the message you will be sending. Also, make sure to include your brand name in the template to help your customers identify and relate to your brand.

6. Avoiding Common DLT Registration Pitfalls

While registering for DLT, you must avoid common pitfalls such as including extra spaces or lines in the template or not following the rules for variables. These mistakes can lead to your registration being rejected. Instead, ensure you use variables only for values that will change due to personalization, and avoid adding unnecessary spaces or lines in your template.

7. Getting Expert Help for DLT Registration

If you're finding the DLT registration process challenging, consider seeking expert help. Many service providers offer support for DLT registration, guiding you through each step and helping you avoid common pitfalls. This can save you time and ensure a smooth registration process.

Frequently Asked Questions

How do I choose the right OTP service provider?

When selecting an OTP SMS service provider, focus on:

  • Delivery reliability and speed
  • Global coverage and local compliance
  • Multi-channel support and fallback
  • Ease of integration
  • Pricing transparency

The right provider should not just send OTPs but ensure they are delivered consistently across regions and networks.

Not all OTP SMS service providers are built the same.

Some optimize for cost, others for flexibility but very few balance delivery reliability, global coverage and ease of use. And that balance is what actually impacts whether your users receive OTPs on time.

If OTP is critical to your product, focus on:

  • reliable delivery (not just sending)
  • multi-channel fallback
  • scalability across regions

Try It for Yourself

Why is multi-channel OTP important?

Relying only on SMS can lead to failed verifications due to:

  • network issues
  • telecom filtering
  • device limitations

Multi-channel OTP systems (SMS + WhatsApp + voice) improve success rates by automatically retrying through alternative channels if one fails.

What is the best OTP SMS service provider in India?

Some of the commonly used OTP SMS service providers in India include MSG91, Exotel and 2Factor.

That said, India has additional challenges like DLT compliance and operator filtering. Platforms that handle these internally while also offering fallback options tend to provide more consistent OTP delivery.

Which is the cheapest OTP service provider?

Providers like Fast2SMS and 2Factor are often considered among the cheapest OTP service providers, especially in India.

However, lower pricing can come with trade-offs such as:

  • lower route quality
  • higher delivery delays
  • limited fallback options

For mission-critical OTP flows, reliability often matters more than just cost.

Which is the best OTP service provider in 2026?

The best OTP service provider depends on your use case.

  • For global scale and flexibility: Twilio, Infobip
  • For cost-effective APIs: Plivo
  • For India-focused SMS OTP: MSG91, Exotel

However, platforms like Message Central stand out by balancing global coverage, multi-channel fallback and ease of deployment, making them suitable for businesses that prioritize delivery reliability.

What is an OTP service provider?

An OTP service provider enables businesses to send temporary verification codes to users via channels like SMS, WhatsApp or voice to authenticate logins, transactions or sign-ups.

Modern OTP SMS service providers go beyond just sending messages, they ensure reliable delivery using optimized routing, retries and sometimes multi-channel fallback.
