Telecom Regulatory Authority of India (TRAI) in its continuous endeavour to create a cleaner and transparent system in the Indian telecom industry has released a new regulation to curb Unsolicited Commercial Communication (UCC) and enhance mobile subscriber privacy, TCCCPR 18 Telecom Commercial Communications Customer Preference Regulation 2018. The Regulation is intended to eliminate spam and fraud which has been a concern for many years. The regulation has mandated the use of Blockchain technology also known as Distributed Ledger Technology (DLT) to implement the solution.


In adherence to the upcoming implementation of these regulations, all businesses, enterprises (principal entities) and Telemarketers are mandated to register with operators on the DLT platform, along with their headers or sender IDs and content templates. TRAI has now directed all operators to restrict traffic for principal entities who have NOT registered themselves and their respective headers or sender IDs on DLT with effect from 31st May 2020.


Note: Only registered templates and headers will be allowed to send communications.


Who is Impacted?

Only LOCAL TRAFFIC (companies with a local business license in India) are mandated for this DLT registration. Local India traffic are A2P traffic using alpha sender IDs.


INTERNATIONAL TRAFFIC who are using ILDO connections are NOT affected by this new regulation. No further action is required.


What needs to be done?

  1. Customers must complete the registration immediately on the DLT platform if they have not completed this process.
  2. In case the customer is already registered on any of the operator portals of DLT, kindly ask them to register all the sender id (Header) and SMS content (Template) that is used by your customer. Only registered template and headers will be allowed to send communication.
  3. Contact your Account Manager to obtain your registration numbers, which will be required to register the templates and headers on the DLT portal.
