Step-by-Step DLT Registration Guide for SMS Services in India
With the introduction of DLT registration in India, there is an established procedure that must be followed prior to the launch of any SMS campaign. Regardless of whether you are utilizing bulk SMS services for promotional purposes or transactional communications, it is important to complete the DLT registration process according to TRAI guidelines.
Selecting a DLT Platform
As the first step, the platform needs to be selected. There are telecom operators such as Airtel, Vodafone Idea, Jio, and BSNL that have their DLT platform on which you can create your account. It is suggested to opt for a single platform initially, but your data will be synchronized among various operators as per your requirement.

- Name of your business entity
- PAN number
- GST number

Your information will be verified by the telecom operator. The entire process takes some time, depending upon the volume of data submitted. After verification, your entity ID will be generated.
