With the onset of the digitalized market in India, things have become easily accessible, and Telephonic communication with people far and wide has become easy and convenient. Apart from the benefits, many challenges are faced by the end users in their day-to-day life. It has further led to a rise in fraudulent and spam messages. To stop such practices, TRAI has mandated DLT registration in India.

The government has initiated DLT in the public interest to ensure control over SMS spam. TRAI DLT regulations bring transparency to the system, get a hold off the futile SMS spam, and protect consumers from fraudulent practices.

DLT records all the transactions between the enterprise and the end users and records and stores details at multiple locations. In the telecom sector record of all the transactions is maintained by a ledger which is made by various networking platforms. DLT provides an unmatchable DLT platform for business networking through SMS.

Introduction (What is DLT) 

The full form of DLT has distributed ledger technology. DLT is a blockchain-based registration system. DLT technology is designed to keep records of all the network participants’ transactions.

In simpler words, DLT platforms are operator-run portals where entities must register by giving their business details. 

Telecom Regulatory Authority of India made it obligatory for all businesses that want to send SMS to a large number of people. They must register their business entity, headers (sender IDs), and templates on any DLT platform. If your business is not registered on these platforms, operators will block your SMS, and you’ll not be able to send any messages to your customers.

DLT registration has been implemented to restrict Unsolicited Commercial Communication (UCC) and improve mobile subscriber privacy within the country.

Why is DLT Registration Important? 

What is DLT Registration? 

DLT registration is an integral part of the SMS marketing strategy. All telemarketers and enterprises who send customer messages must register on TRAI DLT. DLT registration is essential to restrict unsolicited commercial communication and prevent fraudulent customers. 

Studies suggest that people get four or more unwanted messages daily on their mobile phones. Furthermore, the messages don’t stop even after opting for DND. TRAI has stated that it receives more than 40 thousand complaints per month.

Strict regulations have been imposed to eradicate this social evil by introducing DLT registrations by TRAI (Telecom Regulatory Authority of India). Under DLT registrations, companies running unregistered/unapproved SMS business templates will be blocked instantly. To continue sending promotional or transactional messages to customers, the company must register on the DLT platform. 

It makes the system secure and trustworthy as DLT makes an exact copy of data for enhanced security, and all the documents show modifications instantly. A ledger with encrypted files is maintained using key combinations and signatures to keep the data secure. To be more precise, DLT is a systematic digital system that stores, manages, and secures records of all sender IDs and templates.
