Every commercial SMS in India is blocked without a TRAI-approved Entity, Header, and Template on the DLT platform. PING4SMS guides you through registration end-to-end — completely free — so you're sending compliant SMS in days, not weeks.
DLT (Distributed Ledger Technology) is TRAI's blockchain-based system that verifies every business sending commercial SMS in India. Since 2018, any SMS sent without a registered Entity, Header, and Template is blocked at the telecom operator level — no warning, no partial delivery, just silence. Registering on just one operator portal (Jio, Airtel, Vi, or BSNL) is enough — the data syncs across all networks automatically.
Register your Entity once on any single DLT portal — Jio, Airtel, Vi, or BSNL — and your PE ID, Header, and Templates work across every telecom network in India.
Whether you send 100 or 1 crore SMS, TRAI's TCCCPR 2018 mandate applies to every business sending commercial messages — promotional, transactional, OTP, or service alerts.
Document mismatches and template formatting errors cause most rejections. PING4SMS reviews everything before submission, so you avoid the 3-7 day rejection cycle.
Many businesses register their Entity and assume they're done. All three layers must be approved before a single SMS can be delivered.
Register your business to get a unique Principal Entity (PE) ID — your identity across the entire DLT ecosystem. Required documents: PAN, GST certificate, incorporation proof.
Within 2 HoursRegister your 6-character brand Header — the name customers see instead of a random number, e.g. HDFCBK or PING4S. Mapped to a specific message category.
Within 2 HoursSubmit the exact text of every message you'll send, with dynamic fields marked as {#var#}. Each approved template gets a unique Template ID required in every API call.
Within 2 HoursYour Header is locked to one category — sending the wrong content type gets it suspended. Choose carefully at registration.
Document name mismatches across PAN, GST, and incorporation certificates cause the most rejections — keep these consistent and ready.
Business or individual PAN card — mandatory for every entity type, including sole proprietors.
Valid GST registration certificate matching your business name exactly as on the PAN card.
Certificate of Incorporation, Partnership Deed, or Udyam Registration depending on business type.
Government-issued photo ID (Aadhaar/Passport/Voter ID) of the person authorized to sign on behalf of the entity.
An active business email and mobile number for OTP verification during registration.
