TRAI ne 6 May 2025 se ek naya SMS Header Rule implement kiya hai jo transparency aur trust ko boost karta hai. Ab har SMS ke header ke end par ek single-character suffix hota hai jo batata hai ki message ka type kya hai.
Quick Look: P = Promotional | S = Service | T = Transactional | G = Government
The Formula – SMS Header Format
Har SMS ka header is format me aata hai:
[Network][State]-[Brand]-[Type]
Type Codes – Kya Matlab?
P – Promotional (sales, offers, marketing campaigns)
S – Service (app updates, appointment reminders, general engagement)
T – Transactional (bank OTPs, alerts, critical notifications)
G – Government (official messages from govt departments)
Examples
VM-BANK-T – Vodafone India Maharashtra, Bank header, Transactional
KA-ZOMATO-S – Karnataka network, Zomato, Service. Translation: Your food is almost here
VM-BLUDRT-S – Vodafone India Maharashtra, Blue Dart, Service
VD-ABCXYZ-S – Vodafone Delhi network, brand ABCXYZ, Service
Implementation – Kaise Kaam Karta Hai
DLT (Distributed Ledger Technology) platform message scrubbing ke time automatically ye suffix append karta hai. Aap business ya user ho, aapko koi manual change nahi karna.
Telecom Service Providers backend me system update karte hain
Principal Entities aur Telemarketers ko apne templates ya headers change karne ki need nahi
Brand headers jaise NYKAA, ICICIBANK, ZOMATO same rehte hain, end me sirf type suffix add hota hai
Kya Badla Hai
1. Suffixes Ab Mandatory
Har SMS header me ab type-specific suffix zaroor hoga. Isse user ko message open karne se pehle hi category clear ho jati hai.
2. Service Explicit Category Retired
Pehle jo Service Explicit category thi, wo ab hat chuki hai. Is category ke saare messages default taur par Promotional (-P) count honge.
3. Users Ke Liye Zero Effort
Users ko kuch nahi karna. Tagging aur template alignment telecom providers aur bulk SMS vendors handle karte hain.
4. Brand Headers Same
Existing sender names continue kar sakte ho. Bas category suffix end me aa jayega.
Bonus – Spam Se Aur Protection.
7-day complaint window spam ya UCC report karne ke liye. Pehle 3 din the, ab 7 din.
Rogue 10-digit numbers aur unregistered telemarketers par tighter controls. Ab complaint tab bhi file ho sakti hai jab number registry me na ho.
Why It Matters – Trust, Clarity, Control
India me 1.1B+ mobile users ko har din bahut SMS milte hain. Yeh update:
Spam aur fraud risk ko reduce karta hai
Genuine senders ke liye trust aur open rates better banta hai
User ko instant recognition deta hai ki message ka intent kya hai
Jab aap GJ-MEESHO-P ya TN-SBI-T dekhenge, aapko turant samajh aa jayega ki inbox me kya knock kar raha hai.
Who Is Affected
Affected – Telecom Service Providers. Unhe infra update karna hota hai
Not affected – Principal Entities aur Telemarketers. Process same rehta hai
DLT platform khud suffix append karta hai during scrubbing
Messaging Ka Future – Post Suffix World
Yeh sirf regulatory tweak nahi. Yeh ek cultural shift hai jahan SMS ab ek statement of intent ban raha hai.
Possible next steps: real-time opt-out controls
AI-based spam detection
Cross-platform message validation
Bottom line: Users ko pehle hi pata hoga ki woh kya padhne wale hain.
