TRAI Regulations & DLT Compliance for Bulk SMS
In India, Bulk SMS services are regulated by the Telecom Regulatory Authority of India (TRAI) to prevent spam, fraud, and unauthorized messaging. BulkSMS.ca adheres to TRAI’s Distributed Ledger Technology (DLT) compliance, ensuring legitimate, fast, and secure SMS deliveries for businesses, startups, and enterprises.
What is DLT in Bulk SMS?
Distributed Ledger Technology (DLT) is a blockchain-based system that ensures:
Verification & Registration of Bulk SMS senders (Principal Entities & Telemarketers)
Pre-approval of Sender IDs (Headers) and Message Templates
Prevention of spam & unauthorized promotional messaging
Full traceability of SMS campaigns with government oversight
Under TRAI’s mandate, every Bulk SMS provider must register on a DLT platform to continue sending messages.
