The Telecom Communications Customer Preference Regulations, 2018, mandate all senders of commercial bulk SMSes (like OTPs, bank account update), to register their unique SMS headers ID, content and user consent on a blockchain-based platform developed by telecom operators. Any SMS traffic which fails to pass these filters will not be delivered thus helping block fraudulent messages sent by hackers and other cyber criminals. As these checks and balances like headers and templates would allow the verification of identity and purpose of SMSes sent by both companies and banks on the blockchain platform by a process called SMS scrubbing.
Toughening its stance on the implementation of SMS scrubbing, TRAI has now warned defaulting entities to comply with the stipulated requirements by March 31, 2021 “to avoid any disruption in the communication with customers” from April 1, 2021.
TRAI says that “sufficient opportunity” has already been given to these companies to comply with the regulatory requirements and therefore from April 1, 2021, any message that fails in the scrubbing process due to non-compliance will be rejected” by the system. Here’s the list of these 39 defaulters named by TRAI.
