1. What is TRAI DLT (TCCCPR 2018)?
Under the Telecom Commercial Communications Customer Preference Regulations (TCCCPR 2018) enforced by the Telecom Regulatory Authority of India (TRAI), all Application-to-Person (A2P) commercial SMS traffic terminated across Indian telecom operators (Jio, Airtel, Vodafone Idea, BSNL) must be validated on an enterprise Distributed Ledger Technology (DLT) blockchain platform.
2. Core Steps for DLT Onboarding in India
- Principal Entity (PE) Registration: Register your legal corporate entity with official business credentials (PAN, GSTIN, Company Certificate of Incorporation, Authorized Signatory ID) on any major Indian telecom operator DLT portal (such as Jio DLT, Vilpower, PingConnect, or Airtel DLT). Once approved, you receive a unique 19-digit Entity ID (PE ID) recognized across all operators.
- Sender Header (Sender ID) Registration: Register 6-character sender headers. For transactional and service-implicit alerts, numeric or alphanumeric headers are permitted (e.g.
NAMXBK). Promotional marketing headers must be 6 numeric digits mapped to carrier industry prefixes. - Content Template Registration: Every message pattern must be pre-approved on the DLT ledger. Dynamic variables must use standard syntax
{#var#}. Static characters must match exact brand messaging. - PE-TM Binding (Telemarketer Chain Validation): To transmit SMS through an aggregator like NAMX Telecom, the enterprise binds the aggregator registered Telemarketer ID (TM ID) within their operator DLT dashboard.
3. Scrubbing & Filtering Architecture
When an SMS packet hits the Indian carrier gateway, the telecom network performs four instant blockchain checks:
- Is the Header ID active and registered to the sender PE ID?
- Does the template match the approved DLT content pattern with dynamic variable boundaries?
- Is the destination mobile number registered on the National Customer Preference Register (NCPR / NDNC DND list) for promotional categories?
- Is the PE-TM chain cryptographically verified?
Messages passing validation are terminated over direct local SS7 routes in under 1.5 seconds. For dedicated Indian routing and full DLT onboarding assistance, consult our India Bulk SMS corridor or contact the NAMX enterprise sales desk.
